The CMT 550-080X Multi-Purpose TCT Hole Saw delivers a 3-5/32" (80mm) cutting diameter powered by tungsten carbide-tipped (TCT) teeth - a construction-grade material that powers through a wide range of substrates where standard bi-metal saws struggle. Engineered for contractors, electricians, and installers who need reliable, repeatable hole cutting in demanding job-site conditions, this 80mm hole saw handles wood, sheet goods, masonry, plastics, and more in a single versatile tool. With a right-hand rotation and hexagonal shank interface, it integrates cleanly into standard drill and drill press setups.

Key Features

• 3-5/32" (80mm) Cutting Diameter - sized for common trade applications including conduit pass-throughs, recessed fixtures, and pipe penetrations, reducing the need to stock multiple sizes.
• Tungsten Carbide-Tipped (TCT) Construction - harder and more heat-resistant than bi-metal, carbide teeth maintain their edge through abrasive materials like brick, aerated concrete, and laminates that would prematurely dull standard hole saws.
• 4-Tooth Configuration - four evenly spaced carbide teeth balance cutting speed with chip clearance, supporting clean entry and exit cuts across both hard and soft substrates.
• 60mm Cutting Depth - enough penetration for most wall panels, timber framing members, and masonry block thicknesses commonly encountered in construction and renovation work.
• Hexagonal Shank Interface - the hex shank locks positively into drill chucks and dedicated arbors, preventing slippage under the high torque loads generated during masonry and hardwood cutting.
• Right-Hand Rotation (RH) - matches the standard forward rotation of virtually all corded and cordless drills and drill presses, ensuring immediate compatibility without drive adjustments.
• Multi-Material Capability - one hole saw cuts wood, plywood, MDF, laminates, plasterboard, plastics, brick, aerated concrete, and soft tiles, reducing tool swaps and kit complexity on multi-trade jobs.

Why This Product

• Contractors working across multiple material types on a single project can rely on one 80mm hole saw rather than sourcing separate cutters for masonry, timber, and board materials - the TCT construction handles the full range.
• The 60mm cutting depth provides practical clearance for wall assemblies and framing members, so installers can complete penetrations in one pass rather than repositioning or finishing by hand.
• The hexagonal shank eliminates the round-shank slip common with high-torque applications, giving operators consistent, controllable cutting especially in abrasive materials like brick and aerated concrete.
• With 4 carbide teeth and right-hand rotation, this cutter aligns with standard drill and drill press operation - no adapters, no direction changes, and no specialized equipment required to put it to work immediately.
