The Ultimate FAQ —Drill Bits

Choosing a drill bit manufacturer is a task that is often left to experienced recruiters.

Because of the market’s saturation, it’s hard – almost impossible to land on a high quality drill bit supplier.

Luckily for you, we’ve assembled a comprehensive guide on how you can locate and successfully work with the best drill bit manufacturers for both wholesale and retail!

What is a Drill Bit?

A Drill Bit is a cutting tool that is used to create cylindrical holes in solids like metals and wooden planks. Drill bits are held in drill machines and used with torque which creates holes in them.

drill bits manufacturers wholesalers supplier

Why are Drill Bits used?

Drill Bits are cutting tools, it can be used in conjunction with drilling machines to create holes in the solid materials for applications in construction or production of different mechanical parts. Drill Bits are now widely used in manufacturing as well as the construction industry for different applications.

What are the two main types of drill bits?

Drill bits that are currently available in the market are categorized into two types. Rolling cutter bits and fixed cutter bits are two of them. The sizes for these drill bits can be anywhere between 3-⅞ inch to 36 inches.

Rolling Cutter Bits

Rolling cutter bits may also be called roller cone bits or tri-cone bits. Tricone bits in general have three cones. Each cone in this drill bit is individually rotatable with the use of roller bearings which are fitted at the time of their first assembly. These drill bits can be used to drill multiple formations, provided a proper cutter, bearing, and nozzle combination is available.

Rolling cutter bits can further be classified into the following types:

  • Milled-Tooth Bits
  • Tungsten Carbide Insert Bits

Milled Tooth Bits

Milled Tooth Bits have steel tooth cutters. These cutters are fabricated as parts of the bit cone. The bits cut and make formations out when a torque is applied. Teeth on this drill bit may vary in size and shape. The formation of teeth can be soft or hard.

● Soft Formation

Teeth in these drill bits are long, slender, and widely spaced. These teeth with soft formations will produce freshly broken cuttings or chips from soft formations.

● Hard Formation

The teeth in these drill bits are short and closely spaced. Drill bits with these types of formation can be used to produce smaller, ground, round, and crushed cuttings.

Tungsten Carbide Insert Bits

As the name suggests, these types of drill bits have tungsten carbide inserts that are pressed into the bit cones. These inserts can have several shapes including long-extended shapes, round-shaped inserts, and more. The teeth on this bit are also different, based on their formations.

● Soft Formation

These types of insert bits have long-extension and chisel shape inserts.

● Hard Formation

Drill bits with short extensions and rounded inserts have hard formations.

Fixed Cutter Bits

The fixed cutter bits have integrated bit bodies and cutting elements. These bits are employed to excavate holes on the surface using shearing forces instead of using chipping off or gouging out formations. The functioning of these cutter bits is like rolling cutter bits.

With no moving parts such as cones and bearings, these bits are made out of bit bodies fabricated using a steel and tungsten carbide matrix. These bits also have abrasion-resistant cutters integrated which the surface which aid in the cutting operation. A majority of bits available in the market are composed of Polycrystalline Diamond or Natural/ Synthetic Diamond Cutters.

With improvements being carried out in the cutter bit technology, PDC bits are capable of drilling both soft and hard formations. However, care has to be taken when selecting drill bits on very hard formations. You might need to use diamond bits if required.

How to choose the best wholesale Drill Bits?

Though finding the best wholesale drill bits is trickier to find, you can trust the team at our end for your choice of the drill bits. If you are looking to select the one that will suit you the best, there is a need for you to get acquainted with the same.

We’ll first discuss the kinds of drill bits that we have in the market.

Wood Drill Bits

If you are looking to purchase the best wooden drill bits, make sure to check for the small pointed tip at the very end of the drill bit. If you observe closely, you can see spurs on each side. These spurs are responsible to hold the wood in place and carve the same away.

To select the best, make sure you have all these things checked closely by your quality or inspection team.

Masonry Drill Bits

Selecting the best Masonry drill bit requires you to check the gentle sloping tip at the end of the drill bit. Sometimes, the tip of masonry bits can come coated with carbide. This helps retain their sharpness. Masonry Drill Bits work the best with stone and cinder blocks. Also, they work well with tiles as well.

While purchasing the same, look out for these properties so as to select the best for yourself.

drill bits manufacturers wholesalers supplier


Metal Drill Bits

Metal Drill BIts are required to be sharp so as to withstand greater amounts of abrasion forces. These drill bits come with a wide-angled point on one end and are painted in black most of the time. If you are planning to buy new ones, make sure you check the label with the name high-speed steel or HSS printed on it. Metal Drill Bits can be highly versatile and offer more toughness with titanium and cobalt coating. Steel metal Drill Bits can easily drill through soft aluminum whereas to drill through harder metal types, high-speed steel will be required.

What are the possible reasons for a drill bit to break?



There can be more than one reason for the drill bit to break. Possible reasons for a drill bit to break can be too much stress. If the drill bit is not correctly aligned on the spindle, it may cause it to tumble and wobble. Adding to that, if you are applying torque to it in such a situation, it may produce combined stresses. If chips are caused due to the cutting of the metal clog with the drill bit, the additional stress on the bit may cause breakage.

In the second case, if you are using a hand drill, there is a good chance that bending stress combined with unmanaged and uncontrolled torsional force may introduce shearing in the drill bit.

Finally, the compressive stresses built up in the shank may also cause the drill bit to twist and eventually break.

All these different stresses combine to generate a peak principle stress. This peak principle stress when in combination with the rotational force may transform from the compressive load to a tensile force. These stress reversals are the most common reasons why drill bits break apart.

One more reason for the drill bit to break can be that the drill bit material is worn out and fatigued.

Twist Drill Bits

These types of bits consist of angles that are suitable for steel-drilling purposes. These bits can drill through a wide range of material types, however, not at ideal performance.

drill bits manufacturers wholesalers supplier

Masonry Drill Bits

These types of drill bits have a piece of Tungsten Carbide welded or brazed onto the tip. They are also known as TCT Drill bits, TCT expands to Tungsten Carbide-Tipped. They can be identified easily as the tip is comparatively wider than the shank dia. This tip remains blunt in most cases.

drill bits manufacturers wholesalers supplier

SDS Drill Bits

These types of drill bits are employed to cut concrete and engineering bricks. The bits have a shank which fits into the chuck of the drilling machine. They also have a quick-change locking mechanism instead of the twist grip from the conventional drills.

Universal Drill Bits

Like MAsonry drill bits, these drill bits also have a Tungsten Carbide tip, however, this tip is sharpened or edged. This is done so that the drill bit can easily drill across timber and mild steel.

Lip and Spur Drill Bits

These types of Drill Bits are also known as Dowel Drills. With a central point and two cutting edges angled in an opposite direction, these drill bits can stay centered in wood while cutting it faster and using less energy.

Countersink Drill Bits



A countersink drill bit is capable of drilling a shallow recess for a screw head to fit in. Despite its size, the countersink drill bit can outlast carbon steel many times.

drill bits manufacturers wholesalers supplier


Titanium or TiN Drill Bits

These drill bits come coated with superhard titanium nitride coating. This actually makes them stay sharper for longer. This coating helps reduce frictional wear and tear. Some other titanium compounds can also be used to coat the bits. These can be TiAIN and TiCN. TiAIN lasts 5 times longer than HSS.

Flat Drill Bits

These types of drill bits are low cost and low-performance drill bits and form rough holes during wood drilling. The low cost makes them an ideal accessory for drilling large holes.

drill bits manufacturers wholesalers supplier

Augers Drill Bits

These kinds of drill bits are low-speed high-torque drill bits used to drill wood. These bits are known to produce cleaner holes than most other drills.

All other types of drill bits shared above are only different according to the type of use and the building material. To learn more about the kind of drill bit you are selecting you can always check with your drill bits manufacturers.


The Best Drill Bit Suppliers in the Market?

You will find a ton of drill bit manufacturing companies; but how do you weight which the best one is?

Today, the following drill bit manufacturers are considered as the most recommended:

  • DeWALT
  • Irwin
  • Makita
  • Drill America
  • Milwaukee
  • Bosch
  • And many more!

You’ll know these names if you’ve been following the world of drill bits and power tools.

Moreover, you must also know the main downside of choosing to work with these drill bit suppliers – they’re expensive and more often than not, it’s going to be a challenge to strike a deal with them.

Nevertheless, they’re the top manufacturing companies of drill bits and other tools and accessories.

Qualities of Drill Bit Manufacturers to Look For

Choosing a manufacturing partner – especially if it’s wholesale drill bits – is crucial.

Qualities of Drill Bit Manufacturers to Look For
An excellent bulk drill bit wholesaler will never leave out even the smallest details

Saying yes to a manufacturer means that you’re accepting all of their capabilities.

With that in mind, what qualities of drill bit manufacturing companies should you always have an eye on?

Expertise and Capabilities

Their ability to supply you with what you need should be your priority. Imagine being given low-quality drill bits – and you orders 10,000 pieces – would you be pleased?

Try and find out these drill bit suppliers’ capabilities – do they provide OEM or ODM products? Are they capable of manufacturing custom drill bits based on your needs? Would they be able to deliver in time?

The answer to these questions can serve as the foundation of whether or not a drill bit supplier is worth spending time with.

History and Track Record

So a manufacturer answered yes to the question above – what’s the next step?

The next step, simply is, figuring out whether or not they’re true to their word.

Have a glance at their track record and history – are they telling the truth about their skill and expertise? Do clients work and come back to them again?

Client retention is one of the fewest, but most effective ways of determining if a manufacturer will cross rivers for you.

Their record will dictate and give you insight as to how effective and efficient their products and services are.

Rates and Prices

A lot of businesses never consider pricing, especially if they’re looking for quality.

However, prices and rates can tell you a lot about how efficient and how effective a certain manufacturer is.

Find out about the median or the general rates of the products you are about to purchase. Prices that are too good to be true, almost always end up being too much of a fantasy.

Prices that are over-the-roof, on the other hand, might have alternatives that have cheaper and more affordable costs.

Try to find the balance between them, but never compromise quality.

Factory and Manufacturing Plant

A lot of these manufacturers would be open to their drill bits factory.

Their thinking is that being transparent with their manufacturing plant can help them gain more clients – and that is true!

Whenever you are to choose between one drill bit supplier from another, it is rather imperative to take a look at their drill bits factory first.

How they work will tell you a lot about the quality of their products.

Communication Skills

In any aspect of life, communication is key. It’s key to a good relationship, growth, and overall – success.

You may work with the best, the cheapest, and the most skilled manufacturer, but if they fail at communication, you lose a lot, too.

Finding a manufacturer that consistently checks upon you; a manufacturer that always considers you as their first-time client is usually the best.

Would you want to have a business partner that neglects cooperation?

Those are just some of the things you’d want to always have your eyes on, especially if you need bulk drill bits from wholesalers.

Why Choose Chinese Wholesale Drill Bits?

There’s a reason why companies and businesses from the west choose Chinese wholesale drill bit suppliers.


Why Choose Chinese Wholesale Drill Bits
Wholesale Chinese drill bit manufacturers carefully study and assess products one-by-one

Other than the price, they know that drill bit manufacturing competition in China is no joke.

In fact, we can look at it this way – if a region in the U.S. has about 15 drill bit manufacturing companies, China would have about 30 to 50 of those drill bit suppliers – that is how tough competition is.

So what would these drill bit manufacturing companies do for them to get the “golden” sale? They will:

  • Improve their procedures and manufacturing processes
  • Try to lower the costs for clients – they give high discounts
  • Improve and enhance their drill bit factories to showcase to their clients
  • Become lenient when it comes to MOQs
  • Expand and develop their offers, such as wholesale drill bit discounts, etc.
  • Add more to what they’re already offering

Choosing China bulk drill bits from wholesalers would be the best decision you’ll ever make.

Where Can You Purchase Bulk Drill Bits?

There are a lot of drill suppliers in the market that offer wholesale drill bits.

If you want a fair price, going with a Chinese drill bit manufacturing company is key.

We say this not just because of pricing, but also because of the quality these drill bit suppliers can assure you.

Most, if not all Chinese bulk drill bits wholesalers would offer you free samples; and they’ll often deliver it as fast and as high quality as possible.

Why It’s Important to Background Check Drill Bits Manufacturing Companies First

Checking the track record, history, and background of Chinese drill bit manufacturing companies is a significant move before going with one.

Why It's Important to Background Check Drill bits manufacgturer

In essence, their history would reflect the current stature of their products and services.

One good example is to see and talk with some businesses that worked with them. Ask them about how effective and efficient their products and services are; ask them how the package or the orders were delivered; etc.

You can observe and check the quality of work by a manufacturing company by checking out reviews, feedback, talking to previous clients, etc.

How Do They Drill Bit Suppliers Perform in a Drill Bits Factory?

Do you have any idea how drill bit factories look like?

How They Manufacture Drill Bits in a Drill Bit Factory
Crucial step in the manufacturing of drill bits in a drill bit factory

For you to understand better, you need to know what’s happening behind the curtains.  

  1. Drill bits are from raw materials, the most common of which are coiled steel
  2. They’re cut off depending on the size of the drill bit; it’s also in this process where the coils are hardened and straightened
  3. The straightened and cut coil are treated in heat, hardening the steel even more
  4. They’re then cleaned to get rid of whatever debris has been left
  5. Next, they run through a flute machine where large portions of the steel are cut off and removed. This is the process that makes and creates the shape and the physicality of the bit
  6. Then, they run through a machine where the point is finished, as well as the angle of the drill
  7. Lastly, the split pointing procedure creates the secondary cutting edge, ensuring that the bit wouldn’t move or “walk” during usage
  8. Depending on the type of drill bit, the tails are either reduced or flattened
  9. From there, observations and final checking is done; this is important as they dictate whether or not the products would leave the drill bit factory for packaging and distribution

That’s the general procedure of how a drill bit is manufactured and made.

Different manufacturers might have different approaches, but is the general outline of how they are made.

Are There MoQs in Purchasing From Drill Bit Manufacturers?

Yes, most, if not all drill bit manufacturing companies have a minimum order quantity or MoQ.

Having an MoQ helps in controlling the amount of production in drill bit factories. Moreover, it’s also one way of ensuring the stocks for clients.

What’s the Usual Timeframe in Delivering Wholesale Drill Bits?

This will depend on the drill bit manufacturer and their connections when it comes to shipping and delivery.

There are some bulk drill bit wholesalers that manufacture and deliver drill bits in just a month, while there are those that take a month and a half to complete it.

Therefore, it would be wise to ask them about the shipping first so you don’t get in trouble if it doesn’t come at the time you’re expecting it to.

Is it Worth it to Buy Bulk Drill Bits From Wholesalers?

Yes, purchasing bulk drill bits from wholesale drill bit suppliers is something you always need to consider.

You should consider them not only because of their low price, but also because of the fact that you wouldn’t have any problems with stocks.

Many businesses today are biting offers, even if they’re expensive, because of the fact that the drill bit manufacturers they speak with have the exact tools they need.

Furthermore, drill bit manufacturers today are finding it challenging to find stocks for their business.

The reason for these dilemmas include:

  • Large competition;
  • ODM and OEM products from competitors
  • Raw material unavailability
  • And other reasons

That’s why it’s worth purchasing wholesale bulk drill bits from drill bit wholesalers and suppliers!

You’ll never feel the need to find a different drill bits factory for sourcing if you think one step ahead!
