Product Description
CMT 550-035X Multi-Purpose TCT Hole Saw - 1-3/8" (35mm) is a carbide-tipped hole saw engineered for professionals who need fast, reliable hole cutting across a wide range of building materials. Featuring a tungsten carbide (TCT) cutting tip and a hexagonal shank for secure chuck engagement, this 35mm hole saw is designed to handle everything from wood and plywood to plasterboard, plastics, bricks, aerated concrete, and soft tiles - making it a single-tool solution for multi-trade applications on the job site.
Key Features
- 1-3/8" (35mm) cutting diameter - precisely sized for common trade applications such as cable and conduit pass-throughs in wood framing, plasterboard, and masonry substrates.
- 60mm cutting depth - accommodates thicker materials and stacked workpieces in a single pass, reducing the need for repositioning or multiple cuts.
- Tungsten carbide (HW) tooth material - delivers long-lasting edge retention and the ability to cut through abrasive materials including bricks, aerated concrete, and soft tiles that would quickly dull conventional bi-metal saws.
- Single-tooth (Z=1) TCT configuration - optimized for clean, efficient penetration through mixed materials, making this saw suitable across wood products, laminates, MDF, plastics, and masonry-type substrates.
- Hexagonal shank design - ensures a positive, slip-resistant grip in standard drill chucks on cordless drills, corded drills, and drill presses, preventing cam-out during high-load cuts.
- Right-hand (RH) rotation - compatible with all standard right-hand rotation power tools, so no special setup or reverse-mode operation is required.
Why This Product
- One hole saw for multiple material types - the hardened carbide tip cuts wood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles, eliminating the need to swap between specialized saws when working across different substrates on the same job.
- 60mm cutting depth handles real-world framing and masonry thicknesses - deeper than many standard hole saws, this capacity means the 35mm saw can reach through double-layer plasterboard, aerated block work, or thick timber members without requiring an extension.
- Hexagonal shank reduces slippage and rework - the hex shank locks securely in the drill chuck under load, maintaining concentricity and producing consistently clean, round holes even in harder materials.
- Carbide-tipped (TCT) construction extends tool life in abrasive applications - when cutting bricks, aerated concrete, or soft tiles, TCT tooling resists wear far better than bi-metal alternatives, lowering the cost-per-hole over the tool's working life.

Frequently Asked Questions
What materials can this 35mm TCT hole saw cut through?
This carbide-tipped hole saw is a multi-purpose tool rated for cutting wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles. The tungsten carbide (HW) tooth material makes it capable of handling both soft and abrasive substrates that would quickly wear out standard bi-metal hole saws.
What type of drill or machine is this hole saw compatible with?
The hexagonal shank is compatible with standard drill chucks on cordless drills, corded drills, and drill presses. The right-hand (RH) rotation matches all conventional right-hand-rotating power tools - no special settings or reverse mode is needed.
What is the maximum cutting depth this hole saw can achieve?
The cutting depth is 60mm. This allows the saw to cut through thick timber, double-layer plasterboard, aerated concrete block, and other substantial material thicknesses in a single operation without the need for an extension.
Why does this hole saw have only one tooth?
The single-tooth (Z=1) TCT configuration is intentional for a multi-purpose carbide hole saw of this type. A single, precisely ground carbide tooth provides efficient, controlled penetration through a wide variety of materials - including abrasive substrates like brick and aerated concrete - where a multi-tooth design would require significantly more cutting force and could result in faster tip wear.
