Blunt Nose Non Coring Drill Bit - 3/8 Inch with 5/8-11 Thread is a wet cutting bit designed for small diameter holes in granite, engineered stone, marble and porcelain. Use wet at low RPM. Also available in 5/8”-11 thread.
Non-Coring / Disintegrating Diamond Drill: Inside diameter of this diamond drill is offset. It is still considered a diamond core drill because it has a slot on side for coolant to pass through center of the diamond drill. This type of diamond drill leaves no core behind (destroys core when drilling), because its ID (inside diameter) is offset
For use on Wet Coring only. Do not use for Dry Coring
