Product Description
CMT 550-089X Multi-Purpose TCT Hole Saw - 3-1/2" (89mm) is a carbide-tipped hole saw engineered for professionals and tradespeople who need fast, clean holes across a wide range of construction and finish materials. Featuring a right-hand rotation, hexagonal shank, and 4-tooth tungsten carbide (HW) cutting geometry, this 89mm hole cutter delivers reliable performance in wood, panel products, masonry substrates, and more. Whether you are boring holes for electrical work, plumbing rough-in, or tile installation, this multi-purpose TCT saw is built to handle demanding jobsite conditions.
Key Features
- 3-1/2" (89mm) Cutting Diameter - sized for standard rough-in and utility hole applications, reducing the need for secondary sizing passes.
- 60mm Cutting Depth - reaches through thick substrates including doubled lumber, dense panels, and stacked board assemblies without requiring repositioning.
- 4-Tooth Tungsten Carbide (HW) Construction - hard metal carbide tips maintain a sharp cutting edge through abrasive materials like aerated concrete and brick, extending tool life well beyond standard bi-metal saws.
- Hexagonal Shank - locks securely into drill chucks and compatible arbors, preventing slippage under high torque and ensuring consistent rotational transfer.
- Right-Hand Rotation - matches the standard forward drive of all common corded drills, cordless drills, and drill presses for immediate, no-adjustment compatibility.
- Multi-Purpose TCT Design - one 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
- The 4-tooth tungsten carbide (HW) tip geometry is engineered for hard and abrasive materials - making this saw a practical choice for mixed-material jobsites where a single hole saw must perform across masonry, wood products, and sheet goods in the same workday.
- At 89mm in diameter with a 60mm cutting depth, this hole saw covers both diameter and reach requirements that many standard saws cannot combine - reducing tool changes and keeping work moving.
- The hexagonal shank design provides a positive mechanical lock in the drill chuck, which is especially valuable when cutting through resistance-heavy materials like brick or aerated concrete where torque loads are highest.
- Right-hand rotation compatibility with standard drilling equipment means no special setup or reverse-mode configuration - the saw goes to work immediately with the tools already on the job.

Frequently Asked Questions
What is the cutting depth of this hole saw?
The CMT 550-089X has a cutting depth of 60mm, allowing it to bore through thick substrates including doubled panels and dense lumber assemblies in a single pass.
What type of shank does this hole saw use?
This hole saw features a hexagonal shank, which locks positively into compatible drill chucks and arbors to prevent slippage during high-torque cutting operations.
Can this hole saw cut through masonry materials?
Yes. The 4-tooth tungsten carbide (HW) construction is specifically suited for abrasive and hard materials including bricks, aerated concrete, and soft tiles, in addition to wood-based panels and plastics.
What direction does this hole saw rotate?
The CMT 550-089X is designed for right-hand (RH) rotation, which is the standard forward-drive direction used by conventional corded drills, cordless drills, and drill presses - no special configuration required.
