Product Description
The CMT 550-065X Multi-Purpose TCT Hole Saw delivers a 2-9/16 in. (65mm) cutting diameter with tungsten carbide-tipped teeth engineered for demanding multi-material cutting tasks. Designed for professional tradespeople and serious DIYers alike, this hole saw handles a wide range of substrates - from wood and wood composites to plasterboard, plastics, bricks, aerated concrete, and soft tiles - all with a single tool. With a right-hand rotation and a hexagonal shank, this carbide hole saw integrates cleanly into drill setups where speed, versatility, and reliability are non-negotiable.
Key Features
- Tungsten Carbide-Tipped (TCT) Teeth - HW Grade: Hard metal carbide construction resists wear on abrasive materials like brick and aerated concrete, extending the working life of the saw well beyond that of standard bi-metal hole saws.
- 2-9/16 in. (65mm) Cutting Diameter: A precise, consistent bore size that meets common trade requirements for conduit, pipe, and fixture rough-ins across multiple trades.
- 60mm Cutting Depth: Generous cutting depth allows the saw to pass through thick framing members, double-layer drywall assemblies, and composite panels in a single plunge.
- 3-Tooth Configuration: A low tooth count optimized for fast, aggressive stock removal through mixed materials - reducing heat buildup and minimizing clogging during cuts.
- Hexagonal Shank: The hex shank design seats securely in drill chucks and quick-change arbor systems, preventing slippage under torque and ensuring accurate, centered holes.
- Right-Hand Rotation: Standard RH rotation is compatible with virtually all corded drills, cordless drills, and drill presses without any special setup or adapters.
- Multi-Purpose Design: One saw cuts wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles - reducing the number of specialty tools needed on a job site.
Why This Product
- The hard metal (HW) carbide-tipped teeth tackle abrasive materials - like brick and aerated concrete - that quickly destroy standard bi-metal hole saws, making this a more durable choice for mixed-material job sites.
- At 60mm of cutting depth with a 65mm diameter, this hole saw covers a broad range of real-world rough-in scenarios without requiring multiple tool changes or extensions.
- The 3-tooth carbide geometry is specifically configured for multi-material use, balancing cutting speed with tooth durability across soft and hard substrates in a single session.
- The hexagonal shank provides a positive, slip-resistant connection to the arbor, which matters when cutting through harder materials like brick or aerated concrete where torque loads spike unexpectedly.

Frequently Asked Questions
What materials can the CMT 550-065X cut?
This multi-purpose TCT hole saw is designed to cut wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles - making it suitable for a wide variety of trade and renovation applications with a single tool.
What shank type does the 550-065X use, and what drills is it compatible with?
The 550-065X uses a hexagonal shank, which is compatible with standard corded drills, cordless drills, and drill presses. The hex shank seats securely in the arbor to prevent slippage under load.
How deep can this hole saw cut in a single pass?
The 550-065X provides a cutting depth of 60mm, allowing it to bore through thick panels, double-layer assemblies, and structural members without needing to reposition or use an extension.
Why does this hole saw have only 3 teeth?
The 3-tooth carbide configuration is intentional for multi-purpose use. Fewer, larger carbide teeth produce faster, more aggressive cuts while reducing heat and clogging - particularly important when cutting through abrasive materials like brick or aerated concrete where tooth wear is a primary concern.
