The Diablo DHS1500DG 1-1/2 in. Diamond Grit Hole Saw is a specialty hole saw built for drilling clean openings in tile, stone, and glass. This is a diamond grit hole saw designed for boring holes in hard, brittle finish materials. Model Number: DHS1500DG. If you are cutting around shower valves, supply lines, drains, or other penetrations where cracked tile means wasted time and wasted material, this is the right style of cutter.

What makes this hole saw different from a standard bi-metal cup is the abrasive diamond grit edge and continuous rim. Instead of relying on teeth that can grab and chip delicate surfaces, it grinds through the material in a more controlled way. Diablo states this design is built for longer life, faster material removal, smooth drilling, and reduced chipping in masonry-type applications. In practical terms, that means a cleaner finished hole in porcelain tile, ceramic tile, granite, marble, slate, and glass.

The no-pilot-bit design matters more than it sounds. On hard tile and glass, a traditional pilot can wander, crack the surface, or make starting awkward. With the Diablo DHS1500DG 1-1/2 in. Diamond Grit Hole Saw, you start at roughly a 45-degree angle or use a jig, then bring the cup upright as the groove establishes itself. Once you get that technique down, it is a better approach for finish surfaces where control matters more than brute force.

Diablo also built in an open slot design for plug removal. That helps when you are moving from one hole to the next and do not want to waste time fighting the slug out of the cup. Small details like that matter on real jobs, especially when you are laying out multiple penetrations in tile surrounds, backsplashes, countertops, or stone tops.

From a system standpoint, this cutter is made to work with Diablo's Snap-Lock Plus mandrel system. That is a real advantage if you already use Diablo hole saw accessories and want quick cup changes without extra fiddling. It also means this is not the right buy if you expect a generic threaded fit. The compatibility is clear: this hole saw is designed around Diablo's mandrel platform and is intended for use with a hand-held drill.

For the user, this is a strong fit for tile setters, plumbers, remodelers, kitchen and bath installers, and serious DIYers working with finished surfaces. The 1-1/2 inch diameter is a common size for plumbing and fixture-related penetrations, and the diamond grit format is the smarter choice when the material is expensive and easy to damage. If you need one hole saw for rough carpentry, this is not it. If you need controlled, clean cutting in porcelain, stone, or glass, this is exactly the kind of accessory you want in the bag.
