The Diablo DHS0750DG 3/4 in. Diamond Grit Hole Saw is a diamond grit hole saw built for drilling clean holes in tile, stone, and glass. This is a diamond grit hole saw designed for boring small, clean openings in hard brittle materials. Model Number: DHS0750DG. If you are installing plumbing trim, running a small line through tile, or drilling finished stone without beating up the surface, this is the style of cutter you want.

The big story here is the cutting edge. Diablo uses diamond grit rather than conventional teeth, which gives this hole saw longer life and faster material removal in materials that would quickly dull or chip standard hole saws. The continuous rim design matters too. Instead of leaving a rough, chipped edge, it drills with a smoother action that helps protect porcelain tile, ceramic tile, granite, marble, slate, and glass.

On the job, that translates to less drama during the cut. Hard surfaces do not give you much room for error, and a rough-starting cutter can skate, grab, or damage the finish before you are even through the face. Diablo's design is meant to be started at a 45-degree angle or used with a jig, and it does not require a pilot bit. That makes it a practical choice when you need a clean opening in finished material and want to keep the setup simple.

The open slot design is another detail that earns its keep. Once the cut is complete, plug removal is easier, which saves time when you are drilling repeated holes. That sounds like a small thing until you are moving through multiple penetrations in a backsplash, shower surround, countertop, or glass panel and do not want to fight every slug on the way.

Compatibility is straightforward. This hole saw is designed to work with Diablo's Snap-Lock Plus mandrel system for quick cup changes, and it is intended for use with a handheld drill. The minimum chuck size required is 1/4 in., so it fits common drill setups used by tile installers, remodelers, plumbers, and general contractors. If you already run the Snap-Lock Plus system, this size drops right into that workflow.

At 3/4 in. diameter, this size is a good fit for precise penetrations where a larger opening would be overkill. It is especially useful when appearance matters and the finished surface will stay visible. The hole saw is made in Italy and weighs just 0.15 lb, so it is easy to keep in the kit without adding bulk.

This is not a general-purpose wood or metal cutter, and that is exactly the point. The Diablo DHS0750DG 3/4 in. Diamond Grit Hole Saw is for tradespeople and serious DIY users working specifically in tile, stone, and glass who need a cleaner cut, less chipping, and easier changeovers than a basic hole saw can deliver.
