Drill

Whether you buy or rent your drill, there are some factors to consider. Normally, you will use a handheld core drill for certain holes with 3 inches in diameter.

Stand Attachment

Select A Diamond Bit

When choosing the correct diamond core bit, consider aggregate hardness and concrete psi. The diamond core bit should correspond to your drilling material. For harder materials, opt for a softer diamond bond, and a tougher diamond bond for concrete that is softer.

Depth
