This is our professional grade laser welded core bit for those who use core bits everyday. Use it to drill holes from 1" to 6" in diameter in masonry (brick and block) walls, lightweight concrete, and stucco walls.
Slots that cut into the side of the barrel provide cooling of the bit. The large segments are packed with diamonds. Expect more holes than any other one you have previously used. Drilling depth is 9". You will experience no "blowout" of the holes as with hammer bits. Therefore, go ahead and grab our professional core bit today for precise holes and avoid the costly and rather time consuming patchwork. Again, this is simply the best core bit you will ever use.
