The CMT 550-102X Multi-Purpose TCT Hole Saw is a 4" (102mm) tungsten carbide-tipped hole saw engineered for versatile cutting across a wide range of construction and renovation materials. Built with hardmetal (HW) carbide teeth and a right-hand rotation design, this hole saw tackles wood, sheet goods, plasterboard, plastics, masonry, and soft tiles with consistent precision. The hexagonal shank provides a secure, slip-resistant connection to your drill, making it a reliable choice for both jobsite professionals and serious DIYers who need clean, accurate holes in demanding materials.

Key Features

• 4" (102mm) Cutting Diameter - sized for electrical boxes, pipe penetrations, and recessed fixture openings commonly required in construction and remodeling work, reducing the need for multiple tool setups.
• 60mm Cutting Depth - penetrates thick substrates including doubled framing members, deep plasterboard assemblies, and stacked sheet materials in a single pass, saving time and repositioning effort.
• Hardmetal (HW) Tungsten Carbide-Tipped Teeth - carbide construction delivers durability and edge retention far beyond standard bi-metal saws when cutting abrasive materials like brick, aerated concrete, laminates, and soft tiles.
• 5-Tooth Configuration - the optimized 5-tooth geometry balances cutting speed and chip clearance, producing cleaner hole edges and reducing heat buildup in the cut zone.
• Hexagonal Shank Design - the hex shank seats firmly in drill chucks and quick-change arbors, preventing rotation slippage under load and ensuring consistent torque transfer during heavy-duty cuts.
• Right-Hand Rotation - matches the standard forward rotation of corded and cordless drills as well as drill presses, ensuring immediate compatibility with common drilling equipment without adapter adjustments.
• Multi-Purpose Material Compatibility - one hole saw replaces several specialty cutters by handling wood, plywood, MDF, laminates, plasterboard, plastics, brick, aerated concrete, and soft tiles across a single tool platform.

Why This Product

• For contractors and tradespeople who cut across mixed materials on the same job, the hardmetal TCT construction handles abrasive masonry and soft tiles in addition to wood and sheet goods - eliminating the need to switch between dedicated bi-metal and carbide saws.
• The 60mm cutting depth means this 4" hole saw reaches through thick assemblies without having to flip the workpiece or complete the cut from the opposite side, keeping workflows moving efficiently.
• The hexagonal shank provides a locked, non-slip connection that standard round-shank hole saws cannot match, giving users better control and reduced cam-out risk when driving through hard or layered materials.
• At 4" (102mm), this cutter covers one of the most requested hole sizes in electrical, plumbing, and HVAC rough-in work, making it a go-to choice for professionals who need a consistent, accurate opening in drywall, wood framing, and masonry alike.
