Product Description
The CMT 550-020X Multi-Purpose TCT Hole Saw delivers a 25/32" (20mm) cutting diameter with a tungsten carbide-tipped (HW) construction designed to power through a wide range of building materials - from wood and engineered panels to plasterboard, plastics, bricks, aerated concrete, and soft tiles. Engineered for right-hand rotation and fitted with a hexagonal shank, this compact hole saw is sized for jobs where precision and versatility matter most. Whether you are running conduit openings in plasterboard, boring fixture holes in MDF, or cutting through soft masonry, this 20mm carbide hole saw handles the task with the durability that tungsten carbide tooling is known for.
Key Features
- Tungsten Carbide (HW) Tooth Construction - carbide-tipped teeth maintain a sharp cutting edge through abrasive materials like bricks, aerated concrete, and laminates, reducing the need for frequent tool changes or replacements.
- 25/32" (20mm) Cutting Diameter - a precise, consistent bore size suited to conduit pass-throughs, fixture mounting, and small-diameter penetrations in walls and panels.
- 60mm Cutting Depth - enough reach to penetrate standard wall assemblies, thick panels, and layered substrates in a single pass without repositioning.
- Hexagonal Shank - the hex shank interface locks securely into compatible arbors and quick-change systems, preventing slippage under load and ensuring accurate, repeatable cuts.
- Right-Hand Rotation (RH) - matches the standard forward drive of cordless drills, corded drills, and drill presses, making this hole saw immediately compatible with everyday drilling equipment.
- Multi-Material Versatility - one hole 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
- A single 20mm carbide hole saw that handles both wood-based panels and soft masonry means fewer tool swaps and less time spent hunting for the right bit across different phases of a project.
- The 60mm cutting depth gives this compact diameter enough reach for real-world wall and panel thicknesses, so installers are not limited to thin-stock applications.
- Tungsten carbide (HW) tipping is a harder, more wear-resistant material than bi-metal, making this hole saw a stronger choice for abrasive substrates like bricks, aerated concrete, and fiber-reinforced laminates.
- The hexagonal shank design is a practical fit for standard drill chucks and quick-release arbor systems, meaning this saw integrates directly into existing tool setups without adapters or special hardware.

Frequently Asked Questions
What materials can this 20mm hole saw cut?
This TCT hole saw is designed for multi-material use, including wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles. The tungsten carbide (HW) tipping provides the hardness needed to handle both fibrous and abrasive substrates.
What is the cutting depth of the CMT 550-020X?
The cutting depth is 60mm, which provides sufficient reach for penetrating standard wall panels, composite boards, and layered building assemblies in a single pass.
What type of shank does this hole saw use?
The CMT 550-020X uses a hexagonal shank. This shank style locks positively into compatible hex-drive arbors and quick-change systems, preventing rotation under torque and ensuring clean, accurate cuts.
Is this hole saw compatible with standard drills?
Yes. The right-hand (RH) rotation direction matches the standard forward drive of cordless drills, corded drills, and drill presses, making it straightforward to use with common jobsite drilling equipment equipped with a compatible hexagonal arbor.
