CMT 550-019X Multi-Purpose TCT Hole Saw is a 3/4 in. (19mm) diameter carbide-tipped hole saw engineered for fast, clean cutting across a wide range of construction and renovation materials. Featuring a hexagonal shank for secure tool chuck engagement and a right-hand rotation cutting action, this tungsten carbide-tipped (TCT) hole cutter handles demanding applications where a single versatile tool needs to perform across wood, sheet goods, masonry, and more. The 60mm cutting depth gives tradespeople and DIYers alike the reach needed for thick stock and layered assemblies without swapping tools mid-job.

Key Features

• 3/4 in. (19mm) cutting diameter - sized for standard conduit knock-outs, plumbing rough-ins, and hardware installations, making it a practical everyday hole saw for light construction work.
• Tungsten carbide-tipped (TCT) construction - carbide teeth maintain their cutting edge far longer than bi-metal alternatives, reducing the frequency of blade changes and keeping productivity high on multi-material job sites.
• 60mm cutting depth - reaches through thick lumber, stacked sheet goods, and multi-layer wall assemblies in a single pass, eliminating the need to flip workpieces or re-index the hole saw.
• Hexagonal shank design - locks securely into standard hex chucks on cordless drills, corded drills, and drill presses, preventing slippage under torque and improving operator control during the cut.
• Right-hand rotation - matches the standard forward cutting direction of all common drills and drill presses, so setup is straightforward with no special configuration required.
• Multi-purpose TCT formulation - one hole saw cuts wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles, reducing the number of specialized tools a crew needs to carry.

Why This Product

• A single 3/4 in. carbide-tipped hole saw that works across wood products, masonry materials, and board goods means fewer tool changes and a leaner kit for contractors moving between different substrates on the same job.
• The 60mm cutting depth handles thick assemblies - such as framed walls with sheathing or doubled-up lumber - in one pass, saving time compared to shallow hole saws that require repositioning.
• The hexagonal shank provides a positive mechanical lock in hex chucks, so the saw stays on-axis even when cutting abrasive materials like aerated concrete or brick that generate significant side load.
• TCT construction-grade teeth are purpose-built for the punishing variability of multi-material cutting, making this hole saw a reliable choice when the material type changes frequently throughout the workday.
