Diablo Diamond Grit Hole Saw DHS2500DG 2-1/2 Inch (Snap Lock Plus 1/4 Inch Shank Continuous Rim Chip Free Porcelain Tile Granite Glass Drilling)

Diablo DHS2500DG 2-1/2 Inch Continuous Rim Diamond Grit Hole Saw

The Diablo DHS2500DG is a 2-1/2-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 1-5/8-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 large shower valves, drain pipes, and stone countertop pass-throughs using handheld drills without requiring a central pilot bit.

Best Used For:

• Porcelain & Ceramic Tile Shower Valve Penetrations: Drilling smooth 2-1/2-inch clearance holes through dense wall tiles for mixing valves, shower heads, and large drain lines without edge chipping.
• Granite & Marble Countertop Plumbing Installation: Coring clean mounting holes through hard natural stone slabs, slate, and quartz vanity tops for sink fixtures and commercial piping.
• 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.
• Optimized 1-5/8-Inch Depth Capacity: Deep cup barrel easily bores through standard 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.
