Product Description
The CMT 550-133X Multi-Purpose TCT Hole Saw delivers a 5-1/4 in. (133mm) cutting diameter with carbide-tipped (TCT) teeth engineered for demanding multi-material hole cutting tasks. Designed for professionals who need reliable, consistent performance across wood, sheet goods, masonry, and more, this hole saw brings together a hardmetal (HW) tooth construction and a hexagonal shank for secure, no-slip power transfer. Whether you are cutting through plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, or soft tiles, the 550-133X is built to handle the range of materials encountered on busy job sites.
Key Features
- 5-1/4 in. (133mm) Diameter - provides a large, clean bore suited for conduit runs, pipe penetrations, recessed lighting, and other wide-diameter hole cutting applications without requiring multiple passes.
- 60mm Cutting Depth - accommodates standard wall thicknesses, stacked sheet goods, and deeper substrate cuts in a single plunge, reducing repositioning time on the job.
- Hardmetal (HW) Carbide-Tipped Teeth - TCT construction delivers extended tool life compared to bi-metal alternatives when cutting abrasive materials such as fiber-cement board, aerated concrete, and hard laminates.
- 6-Tooth Configuration - the tooth count balances cut speed with surface quality, producing smooth hole edges across wood products, plastics, and masonry-type materials while keeping the saw running efficiently.
- Hexagonal Shank - the hex shank design locks positively into compatible arbors, preventing cam-out and slippage under the high torque loads generated during large-diameter hole cutting.
- Right-Hand Rotation - matches the standard clockwise rotation of corded drills, cordless drills, and drill presses, ensuring straightforward compatibility with common power tools without any special setup.
- Multi-Purpose Material Compatibility - one hole saw handles wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles, reducing the number of specialized tools needed on site.
Why This Product
- Professionals working across mixed-material job sites benefit from a single 5-1/4 in. hole saw that transitions between wood products, masonry substrates, and sheet goods without requiring a tool change for each material type.
- The hardmetal (HW) carbide-tipped tooth construction maintains cutting edge integrity through abrasive materials like aerated concrete and hard laminates - materials that rapidly wear down standard bi-metal teeth.
- With a 60mm cutting depth, this saw reaches through standard-depth assemblies in one pass, eliminating the need for step drilling or repeated repositioning that slows down production work.
- The hexagonal shank provides a positive, slip-resistant connection at the arbor interface, which is especially important at the large 133mm diameter where torque loads are significantly higher than with smaller hole saws.

Frequently Asked Questions
What shank type does the CMT 550-133X use, and which power tools are compatible?
The 550-133X uses a hexagonal shank, which pairs with corded drills, cordless drills, and drill presses equipped with a compatible hex arbor. The hex geometry prevents rotation slippage under the high torque demands of a 5-1/4 in. diameter hole saw.
Can this hole saw cut through masonry materials as well as wood?
Yes. The hardmetal (HW) carbide-tipped teeth are formulated for multi-purpose cutting across a wide range of materials including bricks, aerated concrete, and soft tiles in addition to wood, plywood, MDF, laminates, plasterboard, and plastics.
What is the maximum cutting depth of the CMT 550-133X?
The cutting depth is 60mm, which is sufficient for most standard wall assemblies, door frames, and stacked sheet material applications without requiring multiple passes or step drilling.
What direction does this hole saw rotate, and does it matter for my drill?
The 550-133X is designed for right-hand (RH) rotation, which is the standard clockwise direction used by virtually all corded and cordless drills as well as drill presses. No special settings or reverse-rotation tools are required.
