## Questions & Answers

**Q: Necesito una broca de marmol 3/4**
A: Thanks for your question.
There are only 18mm and 20mm diamond core drill bits in this kind diamond hole saws.
But we have 3/4" vacuum brazed diamond hole saw for drilling marble.
It is not laser welded diamond core drill bit, it vacuum brazed diamond hole saw.
But drilling marble is enough, you could purchase it.

**Q: Is there an adapter to use this bit on an sds max drill? if i find an adapter, would it be ok to use this bit with an sds max drill?**
A: It is not a hammer bit. It is a core drill. Any hammer function WILL destroy it. I used my Dewalt 5/8" arbor grinder. Just remove the 4 1/2" wheel and screw the bit on to it. I drilled 25 holes in A granite boulder. Keep the bit cool or wet.

**Q: can this go through metal?**
A: possibly. It took awhile to get through a 1-hour rated pan deck. I would suggest switching to a metal hole saw bit when you get to the pan deck, especially if it is a 2 hour rated thickness metal.

**Q: Can I use this with a drill press cutting high fire mosaic tiles for a large art installment?**
A: Thanks for your questions.
Yes, our diamond core drill bits could be used.
But our 4 inch diamond hole saws have 5/8"-11 threads which could be operated on angle grinder easily.
If you want to fit our diamond bits on drill machine, you need to prepare an adapter which could change the connection from 5/8-11 to SDS,hex, round shanks.
By the way, if the materials of large art installment is a little soft, we recommend you choose our vaccum brazed diamond hole saw, the laser welded diamond core drill bits are too sharp or aggressive, they are best to cutting granite marble rock or other hard stone materials.
