Diamond Core Drill Bits for Hard Materials
Drill into tile and other hard building materials with diamond core drill bits. By spinning in a circular motion, the bits create uniform holes that pipes, cables, ducts or other tubes can go through. Take a look at our Drill Bits Buying Guide to learn about other possible hole-drilling options.
As with other drill bits, you can attach drilling core bits to any power drill you own. Coring hard materials will strain your drill, so be sure to give the drill a rest occasionally and clean the bit often. If you’re looking for a more powerful drill, refer to our Power Drill Buying Guide for information that’ll help you determine your project needs.
Frequently Asked Questions
Q: What’s a diamond core drill bit?
A: A diamond core drill bit is a bit that makes a large hole. Using small particles of fine diamond, these core drill bits can cut through concrete, marble, stone, porcelain and other hard materials.
Q: How long does a diamond core bit last?
A: A core drill bit can cut from 80 to 250 holes before you’ll need another bit. The factors that determine the longevity of the bit include the thickness and hardness of the materials you’re drilling into and the quality of the bit itself.
Q: Will a diamond core drill bit go through rebar?
A: You should be able to cut a hole through rebar using a diamond core drill bit. In many cases, rebar inside concrete can damage typical masonry bits. Using a core bit with a diamond tip will core concrete smoothly, regardless of whether anything is inside.
