The Diablo DHS1000DG 1 in. Diamond Grit Hole Saw is a diamond grit hole saw designed for drilling clean holes in tile, stone, and glass. Model Number DHS1000DG. This is a hole saw designed for boring through hard, brittle finish materials where standard toothed hole saws tend to chip the surface or wear out too quickly.

What matters here is the cutting edge. Diablo uses a diamond grit rim for longer life and faster material removal, which is exactly what you want when you're working in porcelain tile, ceramic tile, granite, marble, slate, or glass. These materials do not forgive a rough cutter. A diamond grit edge helps the hole saw grind through the surface instead of tearing at it, which supports cleaner results in tile drilling and other finish work.

This hole saw also skips the pilot bit. That matters more than it sounds. On slick tile and glass, a pilot bit can be one more thing to wander or crack the surface if your start is not controlled. Diablo's recommended approach is to start at a 45-degree angle or use a jig, giving you a more controlled entry when drilling finished surfaces. For installers working on bathroom tile, backsplashes, or stone countertops, that is a practical jobsite advantage.

The body design is built around real use, not just catalog specs. An open slot design makes plug removal easier, so you spend less time fighting the slug after the cut. Supplementary product data also points to a continuous rim diamond grit edge, which supports smoother drilling and reduced chipping in masonry-type applications. In plain terms, the cutter is meant to stay consistent and predictable in materials that usually punish cheap accessories.

On the setup side, the Diablo DHS1000DG 1 in. Diamond Grit Hole Saw is made for use with a hand-held drill. It is also compatible with Diablo's SnapLock PLUS mandrel system, which is useful if you already run Diablo hole saw accessories and want faster cup changes between sizes. That kind of compatibility matters for contractors who do repeated rough-ins for plumbing trim, shower hardware, anchors, or pass-through holes in finished tile and stone.

The 1 in. hole saw diameter makes it a practical choice when you need a compact finished opening in hard surfaces. Source data also lists a drilling depth of 2.375 in. and an overall bit length of 4 in., which helps when you're planning around tile, backer, and surface layers. Weight is listed at 0.17 lbs, so it is easy to keep in a drill kit without adding bulk.

Who should buy it? This is a smart pick for tile installers, remodelers, plumbers, electricians, and serious DIY users who need a dedicated diamond hole saw for tile and glass. If your job regularly involves porcelain, glass, or stone, using the right accessory is the difference between a clean install and a cracked finish piece you have to replace.
