CMT 550-038X Multi-Purpose TCT Hole Saw - 1-1/2" (38mm) is a tungsten carbide-tipped hole saw engineered for versatile cutting across a wide range of building materials. With a right-hand rotation, hexagonal shank, and 2-tooth carbide configuration, this 38mm hole cutter is built for contractors, tradespeople, and serious DIYers who need reliable performance when drilling through wood, plasterboard, plastics, masonry, and more. The 60mm cutting depth gives you reach through thick substrates, making this saw a practical choice for rough-in work, electrical installations, and general construction tasks.

Key Features

• Tungsten Carbide (HW) Tooth Material - hard-metal carbide tips stay sharp through abrasive and mixed-material cuts where high-speed steel would wear quickly, reducing the need for frequent blade changes on the job.
• 2-Tooth Carbide Configuration - a lower tooth count with large carbide tips promotes aggressive chip clearance and faster cutting, making each stroke through the material more efficient with less binding.
• 1-1/2" (38mm) Cutting Diameter - a highly common size for electrical conduit, pipe pass-throughs, and general construction holes, giving you a precise, clean opening sized right for standard fittings and knockouts.
• 60mm Cutting Depth - the generous depth capacity allows the saw to cut through thick lumber, stacked boards, double drywall, and other deep substrates in a single pass without repositioning.
• Hexagonal Shank Design - the hex shank seats securely in chuck-driven drills and arbor systems, preventing slippage under load and ensuring positive torque transfer during demanding cuts.
• Right-Hand Rotation (RH) - standard clockwise cutting direction is compatible with virtually all corded drills, cordless drills, and drill presses, so no special tooling or adapters are needed.
• HW (Hard Metal / Carbide) Construction - the carbide material grade is suited to cutting not just wood products but also harder, more abrasive materials like plasterboard, plastics, and soft masonry, reducing the need to swap tools between material types.

Why This Product

• The 60mm cutting depth paired with the 38mm diameter covers the most common rough-in hole size for electrical and plumbing pass-throughs, letting you complete typical trade tasks without switching to a larger or specialty saw.
• Carbide-tipped (TCT) construction means this hole saw handles a wider range of job-site materials - from softwood framing and MDF to plasterboard and plastics - compared to standard bi-metal hole saws that degrade rapidly on abrasive substrates.
• The hexagonal shank and right-hand rotation mean this saw works directly with the corded drills, cordless drills, and drill presses already on your job site - no proprietary machinery or special adapters required.
• With only 2 large carbide teeth, chip evacuation is maximized, which reduces heat buildup and clogging, helping maintain consistent cut quality across repeated holes through varied materials.
