How Do You Use Diamond Products Core Drill Bit?

Diamond core drilling is an art and science.

To achieve your goal,  it is important to use the correct size for your projects.

 

  • Small diamond products core drill bits are perfect for making tiny precision holes.

It is the best choice for jewelry making or handcrafting purposes.

 

Look for diamond products core drill bit with a solid, flat tip to get the job done.

 

You can choose from 0.75mm to 3mm sizes.

 

  • Large diamond-tipped core drill bits make accurate pipe holes, manholes, and so on.

Diamond products core drill bits are available in 3.5mm to 60mm and larger sizes.

 

Large diameter core drilling usually makes the standard 10mm to 700mm diameter holes.

 

Regular core drilling can use 1-foot long diamond products core drill bit.

 

For deeper drilling, you can use bit extensions.

For concrete core drilling, a diamond-tipped core drill bit offers great advantages.

It can easily break up concrete, accessing the ground beneath with less effort.

How Long Does a Diamond Products Core Drill Bit Last?

The lifespan of your diamond products core drill bit depends on various factors such as:

Speed

To maximize the use of the bits and minimize damage to the material, run your drill at the recommended speed.

 

The speed of the diamond products core drill bit should match the application and materials.

  • Abrasive and soft materials can handle higher speeds.
  • Dense and hard materials require slower speeds.

The diameter of your diamond products core drill also influences the drilling speeds.

  • Large diamond drills need around 3 RPMs while smaller drills need higher speeds up to 150,000 plus RPM.
  • The speed will vary with the drilling depth, the material being drilled, the hardness of the material, geometry, density, environment, and goal of the operator.

Density

A diamond products core drill bit that is used to drill tough materials is expected to last shorter.

Bits that are used for coring softer materials are expected to have a longer life.

Pressure

The pressure used to keep the diamond products core drill bit going is also a significant factor.

Applying the right amount of pressure will lengthen the life of your bits.

Starting slow prevents compromising your diamond products core drill bit.

 

  1. Begin with light to medium pressure or the lowest setting.

 

  1. As you feed the drill bit into the material, allow gradual speed and increase it

halfway.

 

  1. The drill will progress at its optimum speed.

Avoid increasing the pressure on your drill.

It will not reduce the completion time.

Instead, it will cause overheat and overload, leading to damage to the material.

It will also cause excessive wear on the diamond products core drill bit.

Never force the diamond drill to complete a hole.

  • When near completion, it is best to reduce the pressure to minimize the chipping of the material.
  • Apply even pressure to make the drill and material meet.

It helps the drill’s surface adjust to the material surface and becomes sharper.

Coolants

To ensure maximum use and keep the diamond bits from cracking, always keep them cool with water or coolant.

The most common reason for diamond products core drill damage is overheating.

It is vital to keep the diamond drill cool during the operation.

Excessive frictional heat can damage the diamond tip of the drill bit.

It also loosens up the metal matrix that keeps the diamond grits intact.

Never run a dry drill bit because it can turn the diamond grits into carbon.

This reverse osmosis process will damage your core drill bit.

You need to use water or coolant to lubricate the diamond product core drill bits.

Aside from keeping it cool, the coolant flushes out abrasive particles or debris during drilling.

The lubrication also keeps the drilling edge clean.

 

  • Water is the best coolant as it delivers an excellent cooling effect at a minimal cost.

It does not leave the diamond product core drill greasy, oily, or contaminated.

 

The best water quality for the coring or drilling process is 90 psi or running water.

 

Check the diamond core bit manufacturers’ recommended water pressure.

 

It will optimize the cooling effect.

 

If you are going to use an additive, the right ratio should be considered as it may require a circulating system.

 

  • Other types of coolants are mineral oils, synthetic water-soluble coolants, and lubricants

 

  • Cold/compressed air – Coolant reduces friction between the diamond product core drill bit and material.

 

It can penetrate the micro-cracks that are generated during the impact of touching.

The surface tension of the coolant plays a crucial role in the drilling operation.

A coolant with lower surface tension easily enters the micro-cracks and wets the diamonds.

It promotes efficient removal of the debris while sustaining overall cooling effects. 

How Many Holes Will a Diamond Products Core Drill Bit Make?

A single sintered diamond products core drill bit can give you about 1,200 holes.

An electroplated diamond core drill bit helps you make 80-120 holes.

The composition and density of the materials you drilled also contribute to the bits’ functionality.

One drill bit can drill up to 15 holes in china plates, or about 250 holes in sea glass.

How Deep Can You Drill Using a Diamond Products Core Drill Bit?

Most simple coring or drilling applications require not more than one-inch depth.

For deeper applications, it is vital to use running coolants from various directions.

A maximum amount of lubrication or water is necessary to keep the drill bit cool.

The spindle travel of the bit will limit its maximum drilling depth capability.

Make sure to check the spindle travel when buying your diamond products core drill bit.

The spindle travel refers to the distance your drill can move upward and downward before touching the surface.

To make deep holes that are beyond the drill bit depth, you can use tube extension.

Drill tube extensions lengthen the drilling depth and are available in different sizes.

Take note that longer drilling depths may require more than one diamond product core drill bit.

 

To ensure the safety of your diamond products core drill when drilling more than 1” depth, use multi-directional coolants

What to Do When Your Diamond Products Core Drill Bit is Having Issues?

While diamond products core drill bits are disposable, optimizing their functionality is in your hands.

The variables that affect their performance and lifespan can be contained to make them efficient.

A slight change in the speed, coolant direction, and feed rate can do the trick.

Matching the size and type of drill bits with the material’s density is also important.

When problems arise during the application, immediate action is necessary.

 

  • If you smell burnt material, stop the operation.

It is possible that the speed of your diamond products core drill is too high.

 

Too much pressure can also cause the burning of the material being drilled.

 

It will also cause the drill bit to become dull, necessitating a new purchase soon.

 

To prevent it from happening, observe the right speed and pressure.

 

Keep your drill bit in optimum condition by applying coolant.

 

  • If the diamond grits of the drill bits are falling away from the shank, reduce the pressure.

 

  • If the diamond products core drill bit snaps, you are applying too much pressure.

The hardened steel shank only breaks when under extreme pressure, so lighten up.

How to Dress a Diamond Products Core Drill Bit?

Diamond products core drill bits can be retrued or dressed several times.

When your drill is “glazed,” you need to use great pressure to help it perform.

 

Dressing clears the “glazed” effect at the bottom of the bit.

It exposes a new layer of sharp diamond that makes the bit more efficient.

However, dressing or retrueing is a highly-sensitive task.

You need to take great care to prevent pulling out the diamonds from the diamond tip.

The best way to dress a diamond core drill bit is drilling a 6mm to a dressing stick.

Do it 2-3 times or up to 20 times when there is too much “glazed” issue.

While dressing the bit, keep your coolant flowing over the stick.

How Do You Know That Your Diamond Products Core Drill Bit Need Dressing?

There are various conditions that can alert you when you need to dress your diamond core bits.

It includes drilling conditions, depth of the hole, and materials being drilled.

The telltale signs are:

 

  • Sound

 

When your diamond products core drill bit starts to generate a “shrill screech” sound, it needs dressing.

 

Immediately stop drilling and get the dressing stick.

 

The sound of a sharp diamond drill bit is “hissing.”

 

 

  • Time cycle

Excessive drilling cycle affects the drill with too much pressure.

 

When you feel it, stop drilling and dress your diamond products core drill bit.

 

  • Pressure

When you feel that your drill needs additional pressure to optimize the performance, stop.

 

Your drill bit needs dressing to regain its normal required pressure.

How to Maintain Your Diamond Products Core Drill Bit?

To get the value of your investment, proper care and maintenance are vital.

You need to sustain the shape and rigidity of the diamond section shape.

Regularly check the tip to guarantee that your diamond products core drill bit is optimized.

Make sure that the drill bit is not losing its roundness and sharpness.

Dressing to expose the cutting edge of the diamond in the bit should be regular.

It is also necessary to periodically check the inside of the diamond products core drill.

This is to ensure that there is no material clog.

When there is a clogged core, immediately wash the debris with water or other coolant sources.
