## Questions & Answers

**Q: how deep can this bit drill into concrete**
A: You can drill to a depth of 6-inches.

**Q: What does the acronym SDS stand for?**
A: SDS stands for "Slotted Drive System".

**Q: Are these compatible? dewalt d25263k d-handle sds rotary hammer with shocks, 1-1/8"**
A: Yes, this is compatible with model D25263K

**Q: Will using running water to flush the hole add to the life of the drill and improving drilling speed, or will water be bad?**
A: In 30 years I've never heard of using water and I've put these bits to the test drilling 20+ holes in a hour or less.  You're chipping "rock", not cutting metal.

Imo water would just gum up the bit, the hole, and makes mess!
