Undoubtedly, these core bits promote faster and cooler drilling in non-reinforced concrete block and masonry materials. They are meant to be used Dry with no water needed which makes for an easy clean-up.

How to use Core Bits
- Make sure you have the correct adaptors for the bits to fit your machine.
- Before drilling, mark out the holes you plan on drilling and make sure that the area is clear. This reduces hazards when drilling through electrical and mechanical conduits.
- Make sure your drilling equipment is functional. Ensure that the motor carriage will move smoothly on the mast. A loose carriage will prevent the bit from drilling deeper than 6”.
Tips & Tricks
If bit production does not resume after encountering concrete again. Stop drilling, lift the bit out of the cut, place a handful of sand in the middle of the core area and resume drilling. The sand will make its way to the face of the bit and will start re-exposing new diamond crystals, increasing the cutting speeds.
