Cut clean, round holes in hard materials with this diamond core drill bit set. The diamond-coated hole saw bits are built for ceramic tile, porcelain, granite, marble, glass and other tough surfaces that ordinary bits crack or dull on.
The hex shank fits standard hex-drive drills and impact drivers, so changing bits is quick and the bit stays seated while you work. It is a practical choice for installing fixtures, running pipes or cables through tile, and general home renovation.
For best results, use the bit with light, steady pressure at low to medium speed, and keep the cutting area cool with a little water or a pause between holes. This helps the diamond coating last longer and gives a smoother edge.
Each order includes the 4-piece core drill bit set in a compact format that is easy to store in a toolbox. A handy addition for DIY users, tilers and handymen who want accurate holes without chipping the surface.
