RockMaster Continuous Rim Diamond Hole Saw Bits are perfect for drilling holes though a wide variety of stone and tile when an exceptionally smooth, clean cut is required. They have a carbide tipped pilot bit with a high quality continuous diamond outer rim. For softer material leave the pilot bit in and for harder material remove the pilot bit for drilling though granite or other hard materials. Suitable for 3/8" drills (threaded versions have 5/8"-11 threads).
Please note that all diamond hole saws, including RockMaster™ brand products, will see increased wear and a decreased lifespan when cutting harder materials.
