Five Tips for Using Diamond Tip Drill Bits
Speed
It’s best to use diamond tip drill bits on very slow speeds. Although faster speeds will reduce cutting time, it will also increase friction and heat. Too much friction and heat will significantly reduce the lifespan of your diamond tip drill bits. It’s best to use drills that have variable speeds because those that have a fixed speed are usually too fast to use with diamond bits.
Lubrication
You should always use use water or coolant to lubricate diamond tip drill bits. This will reduce heat buildup and also prevent the material from getting heat fractures. You should avoid using oil-based lubricants with diamond tip drill bits because they are not effective. Lubricating diamond bits will significantly increase their durability.
Pressure
You should reduce the amount of pressure you use when you’re using diamond tip drill bits to drill hard materials such as hardwood, glass, or ceramic tile. If you exert too much pressure on your diamond tip drill bits when drilling hard materials, friction will quickly cause the bit to overheat. Therefore, make sure you only apply light to medium pressure when working with these extremely hard material.
Depth
If you’re using bonded diamond tip drill bits, you will probably only be able to make a hole 1/2 of an inch deep. It’s best to use sintered drill bits when you need to make deeper holes. Unlike the bonded variety, sintered diamond tip drill bits have diamonds that are embedded in the tip. Therefore, they will be more effective for creating deeper holes.
Lifespan
The lifespan of your diamond tip drill bits will be directly affected by the abrasiveness of the material being drilled. It will also be affected by the speed, pressure, and lubrication that you use. You can increase the lifespan of your diamond tip drill bits by using lower speeds and pressure, while using as much lubrication as possible.
These are a few tips for using diamond tip drill bits. You should make sure that you use them on low speeds. You should also reduce pressure when using diamond tip drill bits on extremely hard materials. This will prevent excessive heat buildup
