Product Description
The CMT 550-168X Multi-Purpose TCT Hole Saw delivers a 6-5/8 in. (168mm) cutting diameter engineered for professionals who need to bore clean, accurate holes through a wide range of building materials. Built with 7 carbide-tipped (TCT) teeth and designed for right-hand rotation, this heavy-duty hole saw tackles wood, sheet goods, plasterboard, and masonry materials with the durability and precision that demanding job site conditions require. Its hexagonal shank provides a secure, torque-resistant connection to your drill or drill press, making it a reliable choice for electricians, plumbers, contractors, and woodworkers who cut large-diameter openings day in and day out.
Key Features
- 6-5/8 in. (168mm) cutting diameter - sized to produce large-diameter openings for conduit, piping, recessed fixtures, and structural penetrations in a single pass
- 7 carbide-tipped (TCT) teeth with HW-grade hard metal construction - hard metal carbide retains a sharp cutting edge far longer than standard bi-metal teeth, reducing replacement frequency and downtime on busy job sites
- 60mm cutting depth - cuts through thick lumber, doubled-up sheet goods, and masonry materials in materials up to 60mm deep without a second setup
- Right-hand (RH) rotation - matched to the standard forward rotation of corded drills, cordless drills, and drill presses so the saw seats and drives correctly without slippage
- Hexagonal shank - the hex profile locks into compatible arbors without slipping under high torque loads, maintaining consistent cutting speed and improving safety during large-diameter boring
- Multi-purpose design - a single saw handles wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles, reducing the number of specialty tools needed on site
- TCT (Tungsten Carbide Tipped) tooth construction - hard metal carbide tips withstand the abrasive demands of masonry and composite materials that quickly dull conventional hole saw teeth
Why This Product
- A 6-5/8 in. diameter combined with a 60mm cutting depth means this saw handles thick structural members and masonry walls in a single plunge - eliminating the need to flip the workpiece or make multiple passes
- Hard metal carbide (HW) teeth make this hole saw genuinely multi-purpose: the same tool that bores through plywood and laminates also cuts bricks, aerated concrete, and soft tiles, reducing tool changeovers across different phases of a project
- The hexagonal shank and right-hand rotation are matched to standard drill and drill press tooling, so the saw integrates directly into an existing drill setup without adapters or modifications
- With 7 carbide-tipped teeth distributed around a 168mm circumference, the saw maintains consistent chip load per tooth, producing cleaner hole edges in wood products and plasterboard compared to fewer-tooth configurations at this diameter

Frequently Asked Questions
What is the cutting depth of this hole saw?
The CMT 550-168X has a cutting depth of 60mm, allowing it to bore through thick lumber, stacked sheet goods, and masonry materials up to that depth in a single pass.
What types of materials can this hole saw cut?
The 550-168X is a multi-purpose TCT hole saw designed to cut wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles. The hard metal carbide (HW) teeth handle both soft and abrasive materials.
What shank type does this hole saw use?
This hole saw uses a hexagonal shank, which locks securely into compatible arbors under high torque loads and is compatible with standard corded drills, cordless drills, and drill presses that accept a hex-drive connection.
How many teeth does this hole saw have, and why does it matter for a 168mm diameter?
The 550-168X has 7 carbide-tipped teeth. At a 6-5/8 in. (168mm) diameter, distributing 7 teeth around the cutting circumference balances chip clearance and cutting speed, helping produce cleaner hole edges in wood products, plasterboard, and masonry materials while reducing heat buildup in the carbide tips.
