Product Description
The CMT 550-057X Multi-Purpose TCT Hole Saw delivers a 2-1/4 inch (57mm) cutting diameter through a wide range of building materials - from wood, plywood, MDF, and laminates to plasterboard, plastics, bricks, aerated concrete, and soft tiles. Built with tungsten carbide (HW) teeth and a right-hand rotation design, this carbide-tipped hole saw is engineered for demanding multi-material drilling tasks where precision and durability matter. The hexagonal shank provides secure chuck engagement, making it a reliable choice for contractors and tradespeople who need consistent results across varied substrates.
Key Features
- 57mm (2-1/4 inch) cutting diameter - sized for common trade applications including conduit knockouts, door hardware prep, and pipe penetrations in walls and panels
- Tungsten carbide (HW) tooth material - provides lasting cutting edge retention across abrasive materials such as bricks, aerated concrete, and soft tiles, reducing the need for frequent tool changes
- 3-tooth TCT configuration - aggressive chip clearance keeps cuts moving efficiently through dense or layered materials like MDF, laminates, and plasterboard
- 60mm cutting depth - accommodates full-thickness cuts through standard wall assemblies, thick lumber, and composite panel materials without repositioning
- Hexagonal shank - locks securely in standard hex-compatible chucks and arbors, preventing slippage during high-torque drilling operations
- Right-hand rotation - compatible with all standard corded and cordless drills as well as drill presses, ensuring broad machine compatibility without special setup
- Multi-purpose design - one hole saw handles wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles, reducing the number of tools needed on the job
Why This Product
- The carbide-tipped (TCT) tooth construction makes this hole saw capable of cutting through both soft materials like plasterboard and hard abrasive materials like bricks and aerated concrete - reducing the need to carry separate hole saws for different substrates on a multi-trade job site.
- At 60mm of cutting depth, this saw reaches through typical wall thicknesses and panel stacks in a single pass, saving time and avoiding the inefficiency of repositioning or using extension arbors for standard applications.
- The hexagonal shank design ensures positive engagement with compatible arbors and chucks, eliminating the round-shank slippage that can occur under the torque loads needed to cut brick, aerated concrete, or dense laminates.
- With a 3-tooth TCT geometry, the saw maintains efficient chip evacuation even in gummy or layered materials such as MDF and plastic sheet goods, helping maintain cut quality and reducing heat buildup at the cutting edge.
