CMT 550-040X Multi-Purpose TCT Hole Saw is a 1-9/16 in. (40mm) carbide-tipped hole saw engineered for professionals who need to cut through a wide range of materials quickly and cleanly. Built with tungsten carbide (HW) teeth and a right-hand rotation design, this 40mm hole cutter handles demanding applications in wood, sheet goods, masonry, and more - making it a go-to tool for contractors, electricians, and remodelers who require a reliable, versatile hole-cutting solution.

Key Features

• Tungsten Carbide (HW) Tooth Construction - hard carbide material stays sharp longer than standard bi-metal teeth, reducing the need for frequent replacement and maintaining clean cut edges across diverse materials.
• 1-9/16 in. (40mm) Cutting Diameter - a precise, consistent bore size suited for conduit, pipe penetrations, recessed hardware, and fixture installations where accuracy matters.
• 60mm Cutting Depth - deep enough to punch through thick lumber, stacked sheet goods, masonry walls, and other substantial substrates in a single pass, saving time on site.
• 2-Tooth TCT Geometry - an aggressive two-tooth configuration moves material efficiently, reduces binding, and delivers fast chip evacuation so cuts stay clean and the saw runs cooler.
• Hexagonal Shank Interface - the hex shank locks securely in chuck-style arbors, preventing slippage under torque and ensuring positive drive transfer from the tool to the saw.
• Right-Hand Rotation - standard RH rotation is compatible with virtually all corded and cordless drills and drill presses, so this saw integrates seamlessly into existing setups without adapter modifications.
• Multi-Purpose Material Compatibility - one saw handles wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles, reducing the number of specialty tools a crew must carry.

Why This Product

• The 60mm cutting depth combined with a carbide-tipped (TCT) two-tooth design means this 40mm hole saw can clear thick walls, laminated panels, and masonry substrates that would stall or wear out ordinary bi-metal saws.
• Multi-material capability in a single 1-9/16 in. saw eliminates the need to switch tools when moving from wood framing to plasterboard to aerated concrete block on the same job site.
• The hexagonal shank provides a positive, slip-resistant connection under high-torque drilling conditions, so cuts stay on center and operator fatigue from tool chatter is minimized.
• Right-hand rotation compatibility means this CMT carbide hole saw works directly with standard cordless drills, corded drills, and drill presses already on the job - no special setup required.
