Diablo DHS1750DG 1-3/4 Inch Continuous Rim Diamond Grit Hole Saw

The Diablo DHS1750DG is a 1-3/4-inch diameter continuous rim diamond grit hole saw engineered to bore precise, chip-free clearance openings through dense porcelain tile, granite, marble, slate, glass, and ceramic.

Technical Specifications

Pro-Tip: When drilling hard porcelain or granite with this diamond grit hole saw, begin the cut at a 45-degree angle to score a starter crescent groove before leveling the bit upright, and apply continuous water spray to prevent thermal glazing of the diamond rim.
