The CMT 550-048X Multi-Purpose TCT Hole Saw is a 1-7/8 in. (48mm) carbide-tipped hole saw engineered for fast, clean hole cutting across a wide range of construction materials. Built with hardmetal (HW) carbide teeth and a right-hand rotation design, this tool delivers the cutting performance and durability that professionals demand when working with wood, composites, sheet materials, and masonry products. The 48mm cutting diameter makes it a go-to choice for electricians, plumbers, contractors, and woodworkers who need reliable, repeatable results in demanding jobsite conditions.

Key Features

• Hardmetal (HW) Carbide Tooth Construction - the HW-grade carbide material maintains a sharp cutting edge longer than standard bi-metal designs, reducing downtime from frequent blade changes and delivering consistent performance through tough materials.
• 1-7/8 in. (48mm) Cutting Diameter - a precise, commonly specified diameter for conduit knockouts, plumbing rough-ins, and cable pass-throughs, giving tradespeople a ready-fit result without secondary sizing work.
• 60mm Cutting Depth - the generous 60mm depth capacity lets users cut through thick lumber, doubled framing members, and insulated panels in a single pass rather than multiple operations.
• 2-Tooth TCT Geometry - the 2-tooth configuration optimizes chip evacuation and reduces heat buildup during the cut, extending tool life and improving cut quality in wood, laminates, and soft masonry.
• Hexagonal Shank - the hex shank design locks securely in compatible arbors without slipping under torque, maintaining accurate hole position and reducing operator fatigue during repetitive drilling tasks.
• Right-Hand Rotation - matches the standard forward rotation of corded drills, cordless drills, and drill presses, making this hole saw immediately compatible with the most common drive tools on the jobsite.
• Multi-Purpose TCT Design - one hole saw handles wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles, reducing the number of specialty tools a tradesperson needs to carry.

Why This Product

• The 60mm cutting depth combined with hardmetal carbide teeth means this hole saw can power through thick structural members and layered assemblies that would stall or damage a lesser tool - a direct productivity advantage on framing and rough-in work.
• At 1-7/8 in. (48mm), this diameter aligns with widely specified trade sizes for conduit and pipe openings, which means fewer custom adjustments and faster rough-in completion on commercial and residential projects.
• The multi-material TCT cutting capability means a single tool moves from cutting plasterboard partitions to soft masonry blocks without a blade swap, keeping work moving across mixed-substrate jobsites.
• The hexagonal shank and 2-tooth geometry work together to deliver secure drive engagement and efficient chip clearance - two factors that directly reduce the heat and vibration that wear out hole saws prematurely.
