Diablo Diamond Grit Hole Saw DHS0875DG 7/8 Inch (Snap Lock Plus 1/4 Inch Shank Continuous Rim Chip Free Porcelain Tile Granite Glass Drilling)

Diablo DHS0875DG 7/8 Inch Continuous Rim Diamond Grit Hole Saw

The Diablo DHS0875DG is a 7/8-inch diameter continuous rim diamond grit hole saw engineered to bore precise, chip-free clearance openings through fragile porcelain tile, ceramic, granite, marble, slate, and glass. Built with an industrial diamond grit cutting edge and a 2-inch cutting depth capacity, this masonry cup tool pairs with Diablo's Snap-Lock Plus™ mandrel system and standard 1/4-inch drill shanks to execute smooth material removal without cracking hard substrates. Featuring an integrated open-slot system for rapid core plug ejection, it allows tile installers and plumbers to drill mounting holes for small water lines, anchor bolts, and bathroom fixtures using handheld drills without requiring a central pilot bit.

Best Used For:

• Porcelain & Ceramic Tile Fixture Penetrations: Drilling smooth 7/8-inch clearance holes through dense wall and floor tiles for small water stub-outs and mounting hardware without edge chipping.
• Granite & Marble Countertop Anchor Installation: Coring clean holes through hard natural stone slabs, slate, and quartz vanity tops for undermount sink anchors and small plumbing lines.
• Glass & Delicate Masonry Drilling: Executing controlled, crack-free circular cuts in glass panels, mirror tiles, and dense masonry substrates using handheld drill drivers.

Key Performance & Safety Features

• Continuous Rim Diamond Edge: High-density industrial diamond particles bond to a continuous rim profile to deliver smooth, burn-free cuts in ultra-hard tiles.
• Snap-Lock Plus™ Mandrel Compatibility: Connects directly to tool-free mandrel systems to allow fast cup swaps and swift core plug clearing.
• Integrated Plug Ejection Open Slot: Large side slot access permits easy insertion of screwdrivers to pop out trapped stone and tile plugs quickly.
• No Pilot Bit Requirement: Engineered to start cuts smoothly at a 45-degree angle or with a guide template, eliminating central pilot bit cracking in delicate glass and stone.
• Universal 1/4-Inch Shank Fitment: Mounts securely into standard 1/4-inch power drill chucks and impact drivers for versatile jobsite use.
• Extended 2-Inch Depth Capacity: Deep cup barrel easily bores through thick floor tiles, backer boards, and natural stone slabs in a single pass.

Technical Specifications

Pro-Tip: When coring dense porcelain or granite with this diamond grit hole saw, start the cut at a 45-degree angle until a shallow crescent groove is established, then flatten the drill while applying water cooling to prevent heat buildup and edge glazing.
