CMT 550-029X Multi-Purpose TCT Hole Saw - 1-1/8" (29mm) is a tungsten carbide-tipped hole cutter engineered for professionals who need a single, versatile tool that moves efficiently through a wide range of building materials. With a right-hand rotation, hexagonal shank, and a generous 60mm cutting depth, this 29mm hole saw handles everything from wood-based panels and plasterboard to plastics, bricks, aerated concrete, and soft tiles - making it an ideal go-to cutter for general construction, renovation, and finishing work.

Key Features

• 1-1/8" (29mm) cutting diameter - precision-sized for common rough-in and finish holes in electrical, plumbing, and carpentry applications, reducing the need for additional trimming or enlarging.
• 60mm cutting depth - reaches through thicker substrates including double-stud walls, thick timber members, and layered panels in a single pass, saving time on repositioning or re-cutting.
• Tungsten carbide-tipped (TCT) tooth construction - the hardened carbide edge maintains a sharp cutting geometry through abrasive materials such as brick, aerated concrete, and laminates where high-speed steel would dull rapidly.
• Multi-purpose material compatibility - one hole saw cuts wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles, eliminating the need to swap between dedicated cutters for different substrates.
• Right-hand rotation - matches the standard rotation direction of corded drills, cordless drills, and drill presses for straightforward, no-configuration use.
• Hexagonal shank interface - locks positively into hex-drive chucks and compatible arbors, resisting slippage under load and ensuring accurate, concentric cuts.

Why This Product

• The TCT construction grade carbide tooth is formulated to cut through abrasive materials - brick, aerated concrete, and laminates - that quickly degrade standard bi-metal hole saws, making this a durable choice for mixed-material construction sites.
• A 60mm cutting depth means this 29mm hole saw handles thick assemblies without requiring multiple setups, keeping work moving on demanding renovation and new construction projects.
• The hexagonal shank design provides a slip-resistant drive connection, which is especially valuable when boring through hard or inconsistent materials where torque spikes can cause round-shank tools to spin in the chuck.
• Multi-purpose compatibility across wood products, plastics, masonry-adjacent materials, and tiles means a single 1-1/8" cutter covers the majority of hole-cutting tasks encountered in general building trades, reducing tool inventory and cost.
