CMT Diamond Dry Hole Saw - 2-1/8" x 1-9/16" x 2-3/8" is a premium dry-cutting hole saw engineered for drilling through hard tiles, natural stones, and artificial stone surfaces. Designed for use with an angle grinder via a 5/8"-11UNC threaded spindle, this diamond-coated tool delivers fast, precise circular cuts in ceramic tile, gres, granite, marble, and engineered stone materials without the need for water cooling - thanks to its built-in cooling wax technology. Whether you are tackling a stone countertop installation or a hard tile flooring project, this hole saw is built to perform cleanly and consistently.

Key Features

• Diamond Dry Cutting Design - uses diamond grit abrasive to cut hard tiles, stones, and artificial stones dry, eliminating the need for water hookups on the job site and making the tool highly portable and convenient.
• Filled with Cooling Wax - the wax melts during drilling to manage heat at the cutting interface, protecting both the blade and the workpiece material and helping extend the usable life of the saw.
• 5/8"-11UNC Threaded Shank - the standard angle grinder thread pattern means this hole saw connects directly to most angle grinders without adapters, saving setup time and keeping the tool secure during operation.
• 2-1/8" Cutting Diameter - sized to create clean round openings for fixtures, fasteners, pipes, or conduit in stone and tile applications where precision matters.
• 1-9/16" Cutting Depth - provides sufficient depth capacity for cutting through standard tile thicknesses and most natural or artificial stone slabs in a single pass.
• Right-Hand Rotation (RH) - engineered for the standard rotation direction of angle grinders, ensuring consistent engagement of the diamond cutting surface and predictable cutting performance.
• Up to 14,000 RPM Rated - high rotational speed capability means the saw can be run at angle grinder speeds without risk of overloading the tool, giving professionals flexibility in their cutting pace.

Why This Product

• Dry cutting with built-in cooling wax makes this hole saw a practical choice for stone and tile work where running water is unavailable or inconvenient - no wet saw setup required for circular penetrations.
• The 5/8"-11UNC spindle thread is the standard connection for angle grinders, so this saw integrates directly with tools already on the job site rather than requiring specialty adapters or equipment.
• With a 2-1/8" diameter and 1-9/16" cutting depth, this saw covers common hole sizes needed for plumbing, electrical, and fixture rough-in work in hard tile and stone countertop or floor applications.
• The diamond abrasive material (DP) is specifically suited for the hardest tile and stone surfaces - including granite, marble, and engineered stones - where standard carbide or bi-metal hole saws would fail or wear out prematurely.
