Basic's of How to core drill
Though a Core drill bit is suppose to be self sharpening.If you are a core drill operator then you have been here. You push, and push as hard as you can but the core drill bit just does not seem to be cutting.
Here is what we sometimes do with older core drill bits (in a pinch) to get them sharpened and cutting like new.
A) Take a good roofing hammer and use the claw side of the hammer to gently tap the top edges of the core drill bit.
B) Another way is to use good silcate sand and throw it in your concrete hole every once in while to deglaze the diamonds in the bit.
C) Turn the water supply all the way off and run the core drill bit dry for just a bit, then slowly add water. Repeat until the core drill bit starts cutting the concrete.
