CMT 550-073X Multi-Purpose TCT Hole Saw is a 2-7/8 in. (73mm) carbide-tipped hole saw engineered for demanding multi-material cutting applications. Built with tungsten carbide (HW) teeth and a 3-tooth configuration, this hole saw delivers clean, fast cuts through wood, sheet goods, plasterboard, plastics, and masonry-type materials. The hexagonal shank design ensures a secure, positive drive connection, making it a reliable choice for professionals who need consistent results across a wide range of substrates on the job site.

Key Features

• 73mm (2-7/8 in.) cutting diameter - sized for standard rough-in holes such as plumbing pass-throughs, electrical boxes, and HVAC openings, reducing the need to switch saws mid-task.
• 60mm cutting depth - deep enough to cut through thick framing lumber, double-layer drywall, or stacked sheet materials in a single pass, saving time and effort.
• Tungsten carbide (HW) tooth material - harder and more wear-resistant than standard bi-metal teeth, allowing the saw to maintain cutting edge sharpness across abrasive materials like aerated concrete and laminates.
• 3-tooth TCT configuration - aggressive tooth count optimized for fast material removal in multi-purpose applications, reducing cut time compared to finer-tooth designs on thick or dense substrates.
• Hexagonal shank - provides a no-slip connection with compatible arbors, eliminating shank slippage under high torque loads and improving drive efficiency.
• Right-hand (RH) rotation - matches the standard rotation direction of corded drills, cordless drills, and drill presses, ensuring immediate compatibility with common power tools.
• Multi-purpose design - a single saw handles wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles, reducing the number of specialized tools needed on site.

Why This Product

• Contractors and tradespeople who work across multiple materials - from wood framing to plasterboard to light masonry - can rely on a single 73mm hole saw rather than carrying separate tools for each substrate, streamlining the workflow.
• The 60mm cutting depth accommodates real-world construction assemblies such as thick studs, layered panels, and built-up materials that shallower hole saws cannot handle in one pass.
• The tungsten carbide tooth construction resists the dulling and chipping that typically shortens the life of bi-metal saws when cutting abrasive materials like aerated concrete or fiber-reinforced laminates, resulting in longer service life.
• The hexagonal shank locks firmly into compatible arbors under heavy drilling loads, making this hole saw a dependable choice for high-torque cordless drills and drill presses where round-shank saws can slip and lose concentric tracking.
