CMT 550-083X Multi-Purpose TCT Hole Saw 3-1/4" (83mm) is a professional-grade, carbide-tipped hole saw engineered for contractors and tradespeople who need fast, reliable hole cutting across a wide range of building materials. Constructed with hardmetal (HW) carbide teeth and designed for right-hand rotation, this 83mm hole saw delivers consistent performance in wood, sheet goods, and light masonry applications - making it a versatile single-tool solution for multi-trade job sites.

Key Features

• 3-1/4" (83mm) cutting diameter - sized for standard rough-in and trade applications including pipe openings, cable routes, and HVAC penetrations through a variety of substrates.
• 60mm cutting depth - provides sufficient reach to cut through standard wall framing, stacked panels, and thick composite materials in a single pass without repositioning.
• Hardmetal (HW) carbide-tipped teeth - purpose-built carbide construction maintains edge sharpness far longer than bi-metal alternatives, reducing the need for frequent replacement when cutting abrasive or demanding materials.
• 4-tooth tooth count - an aggressive tooth geometry that promotes rapid material removal, allowing faster hole completion and less heat buildup during extended cutting sessions.
• Hexagonal shank design - the hex shank interface locks securely in the arbor, preventing slippage during high-torque cutting and ensuring consistent concentricity for clean, accurate holes.
• Right-hand rotation - compatible with standard corded drills, cordless drills, and drill presses, meaning no specialized equipment is required for everyday jobsite use.
• Multi-purpose material capability - cuts wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles, eliminating the need to swap between dedicated hole saws for different substrates.

Why This Product

• The HW carbide tooth construction holds up to abrasive materials like bricks and aerated concrete that would rapidly dull standard bi-metal hole saws - a practical advantage when working across mixed-material walls or renovation sites.
• At 60mm cutting depth, this saw reaches through thick framing members and multi-layer board assemblies that shallower hole saws cannot complete in a single pass, saving setup time on site.
• The 4-tooth carbide configuration handles everything from soft plasterboard to hard masonry substrates, meaning one hole saw covers multiple trade tasks rather than requiring a separate tool for each material type.
• The hexagonal shank provides a positive, no-slip connection that keeps the saw centered and stable during drilling, resulting in cleaner hole edges and reduced risk of workpiece damage.
