Product Description
CMT 550-114X Multi-Purpose TCT Hole Saw - 4-1/2" (114mm) is a heavy-duty, carbide-tipped hole saw engineered for contractors and tradespeople who need reliable, clean cuts across a wide range of materials. Built with tungsten carbide (HW) teeth and a right-hand rotation design, this 4-1/2 inch hole saw delivers consistent performance when cutting through wood, composites, plastics, masonry, and more. The hexagonal shank ensures secure, wobble-free engagement in standard drill chucks, making it a go-to tool for demanding job site applications where precision and durability matter.
Key Features
- 4-1/2" (114mm) Cutting Diameter - sized to handle a broad range of hole-cutting tasks including electrical boxes, pipe penetrations, and recessed fixtures without requiring multiple tool setups.
- 60mm Cutting Depth - accommodates thick stock, double-layer panels, and masonry materials in a single pass, reducing the need for repositioning or multiple cuts.
- Tungsten Carbide (HW) Tooth Construction - hard-metal tipped teeth maintain a sharp cutting edge significantly longer than standard bi-metal hole saws, especially in abrasive or hard materials like bricks and aerated concrete.
- 5-Tooth Geometry - optimized tooth count balances fast material removal with smooth cut edges, reducing tear-out in wood, MDF, laminates, and plasterboard.
- Hexagonal Shank - locks securely into drill chucks without slipping under torque, providing positive drive engagement and improved safety during high-load cuts.
- Right-Hand Rotation (RH) - compatible with all standard corded and cordless drills for straightforward, no-fuss operation on any typical job site.
- Multi-Purpose Material Capability - one tool handles wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles, reducing the number of specialty bits you need to carry.
Why This Product
- Versatility across hard and soft materials - the carbide-tipped (TCT) construction means a single hole saw can move from cutting softwood framing to plasterboard to aerated concrete blocks without switching tools, saving time on multi-trade projects.
- Long-lasting edge retention in abrasive conditions - tungsten carbide teeth resist the dulling effect of gritty or hard materials like bricks and soft tiles, giving tradespeople more cuts per tool before replacement is needed.
- Secure chuck engagement every time - the hexagonal shank design prevents the rotation slippage that round-shank hole saws can experience under heavy load, reducing risk and improving cut accuracy.
- Practical 60mm cutting depth - deep enough for real-world installations involving layered wall assemblies, thick timber, or block-work without needing an extended arbor or secondary tool.

Frequently Asked Questions
What materials can the CMT 550-114X cut through?
This TCT hole saw is designed as a multi-purpose cutting tool capable of cutting wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles - making it suitable for a wide variety of construction and renovation applications.
What type of drill chuck does the hexagonal shank fit?
The hexagonal shank is designed for use with standard drill chucks found on cordless drills, corded drills, and drill presses. The hex geometry prevents slipping under torque, which is especially important during demanding cuts in harder materials like brick or aerated concrete.
What is the maximum cutting depth of this hole saw?
The CMT 550-114X has a cutting depth of 60mm, which is deep enough for most wall assemblies, thick timber panels, and masonry block applications encountered in typical construction and installation work.
Why are carbide-tipped (TCT) teeth an advantage over standard bi-metal hole saw teeth?
Tungsten carbide (HW) teeth are significantly harder than standard high-speed steel or bi-metal teeth, which means they hold a sharp cutting edge longer - particularly in abrasive materials such as bricks, soft tiles, and aerated concrete. This results in more cuts per tool life and consistent hole quality over time.
