CMT 550-092X Multi-Purpose TCT Hole Saw is a 3-5/8" (92mm) carbide-tipped hole cutter built for professionals who need reliable, repeatable performance across a wide range of materials. Featuring tungsten carbide (HW) cutting teeth on a right-hand rotation body, this hole saw handles demanding applications in wood, composite sheet goods, plasterboard, plastics, masonry, and more - all with a 60mm cutting depth that gives users ample reach through thick substrates. The hexagonal shank provides a secure, positive fit in cordless and corded drills, making it a practical choice for electricians, plumbers, contractors, and general tradespeople working on-site or in a shop environment.

Key Features

• Tungsten Carbide (HW) Tooth Material - hard-wearing carbide tips maintain a sharp cutting edge far longer than bi-metal alternatives, reducing the frequency of tool changes and lowering cost per hole over time.
• 3-5/8" (92mm) Cutting Diameter - sized for common electrical, plumbing, and HVAC rough-in openings, giving tradespeople an exact fit without the need for additional enlarging or finishing.
• 60mm Cutting Depth - penetrates through thick framing members, double-layer drywall assemblies, and dense masonry blocks in a single pass, eliminating the need to re-position or flip the workpiece.
• 4-Tooth Configuration - an aggressive, open gullet design with 4 TCT teeth promotes fast chip evacuation and reduces heat build-up, keeping the saw cutting cleanly through abrasive materials like aerated concrete and soft tile.
• Right-Hand (RH) Rotation - compatible with the standard forward drive direction of all common drills and drill presses, so setup is straightforward with no reverse-mode adjustments required.
• Hexagonal Shank - the hex shank geometry locks firmly in the chuck, preventing slippage under the high torque loads generated when cutting through bricks, laminates, and dense plastics.
• Multi-Purpose Design - a single hole saw replaces several material-specific cutters in a tool kit, cutting through wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles without switching tools.

Why This Product

• When a job requires cutting clean, accurate 3-5/8" (92mm) openings through mixed materials on the same worksite, the carbide-tipped construction handles the transition from soft wood panels to abrasive masonry substrates without compromising cut quality.
• The 60mm cutting depth addresses thick-wall installations - whether passing through stacked drywall, structural lumber, or dense block - without requiring a second pass or a longer specialty saw.
• With only 4 large carbide teeth and an open gullet, the saw sheds debris aggressively, which translates directly to less downtime clearing chips and less risk of the saw binding in gummy or dusty materials.
• The hexagonal shank and right-hand rotation mean the saw drops straight into a standard drill or drill press without adapters or special setup - a practical advantage on busy job sites where speed and simplicity matter.
