◢FAQ

What materials can I use these drill bits on?

The drill bits are designed for dry or wet drilling on hard materials including porcelain tile, granite, marble, and ceramic.

I need to make a hole larger or smoother after drilling. Which tool should I use?

For enlarging, shaping, or rounding the edges of an existing hole, you should use the Finger Bit. It works on porcelain, hard ceramic, marble, and granite.

How can I create a smooth, beveled edge on a hole?

Use the Chamfer Bit. It is specifically designed for chamfering, widening, grinding, and polishing the exit holes of your drillings for a clean, finished look.

I have a standard SDS drill. Can I use these bits with it?

Yes, you can. By using the included SDS Adapter, you can fit all the 5/8-11 threaded bits (Drill Bits, Finger Bit, Chamfer Bit) onto your standard SDS drill.

What is the key feature that makes these bits effective and long-lasting?

They are manufactured using vacuum brazed technology. This ensures high efficiency, fast drilling, a long lifetime, less chipping, and minimizes breakage and material loss.

What is the actual drilling depth of the Drill Bits?

The total length of the Drill Bits is 60mm, with a diamond segment height of 10mm. The effective drilling depth will be less than the total length, depending on the tool holder, but the workable diamond-cutting portion is 10mm tall. For precise depth requirements, please check the specific bit and your setup.
