The CMT 550-160X Multi-Purpose TCT Hole Saw delivers a 6-5/16 in. (160mm) cutting diameter with 7 hardmetal carbide-tipped teeth engineered to bore clean, fast holes through a wide variety of building materials. Designed for professionals who work across multiple substrates - from structural wood and plywood to plasterboard, plastics, and masonry products - this TCT hole saw handles demanding cutting tasks that would wear out standard bi-metal saws far sooner. The right-hand rotation and hexagonal shank design make it compatible with standard drill configurations, and the 60mm cutting depth gives tradespeople the clearance needed for most wall and floor penetration work.

Key Features

• 6-5/16 in. (160mm) cutting diameter - sized to handle large-bore penetrations for conduit, pipe, HVAC, and fixture cutouts in a single pass, eliminating the need to step up through multiple hole sizes.
• 7 hardmetal carbide-tipped (TCT) teeth - tungsten carbide cutting edges stay sharp far longer than standard steel teeth, reducing downtime from frequent blade changes when cutting abrasive materials like laminates, aerated concrete, or soft tiles.
• 60mm cutting depth - provides enough reach to cut through typical wall assemblies, framing members, and thick panel materials without bottoming out mid-cut.
• Multi-purpose construction grade design - cuts wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles, meaning one hole saw replaces multiple application-specific tools on the job site.
• Right-hand (RH) rotation - matches the standard forward drive direction of corded drills, cordless drills, and drill presses, so setup is straightforward with no special configuration required.
• Hexagonal shank - locks securely into drill chucks and arbors without slipping under load, maintaining consistent torque transfer even during heavy cuts through dense or abrasive substrates.

Why This Product

• A single 6-5/16 in. TCT hole saw that cuts wood, masonry, laminates, plastics, and plasterboard eliminates the need to carry multiple application-specific blades - a practical advantage for multi-trade professionals or contractors moving between material types on a single job.
• The 7-tooth carbide-tipped construction maintains cutting performance through abrasive materials like aerated concrete and soft tiles that quickly degrade standard bi-metal hole saws, reducing the cost and frequency of blade replacement over time.
• With a 60mm cutting depth and a hexagonal shank, this hole saw is ready to work immediately with compatible drill equipment - the geometry prevents chuck slippage under the torque loads required for large-diameter cuts.
• At 160mm in diameter, this tool targets the large-bore hole cutting range commonly required for electrical, plumbing, and HVAC rough-in work, making it a purpose-matched choice for these high-frequency professional applications.
