CMT 550-044X Multi-Purpose TCT Hole Saw - 1-3/4" (44mm) is a carbide-tipped hole cutting tool engineered for professionals and serious DIYers who need fast, clean holes across a wide range of building materials. Built with tungsten carbide (HW) teeth, this 44mm hole saw handles demanding applications in wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles - delivering the kind of cutting performance that standard bi-metal saws simply cannot match. The right-hand rotation design and hexagonal shank make it compatible with standard drill configurations, while the 60mm cutting depth gives users enough reach for thick substrates and deep installations.

Key Features

• Tungsten Carbide (HW) Tooth Material - hard carbide tips stay sharp through tough materials like bricks, aerated concrete, and fiber cement, reducing the frequency of blade changes and lowering cost per hole over time.
• 44mm (1-3/4") Cutting Diameter - precisely sized for common electrical, plumbing, and HVAC rough-in work, fitting standard conduit and pipe pass-through requirements without over-cutting.
• 60mm Cutting Depth - enough reach to cut through thick wall assemblies, doubled-up plywood, and masonry blocks in a single pass, eliminating the need for multiple setups.
• 2-Tooth TCT Configuration - a low tooth count optimized for aggressive chip clearance in soft masonry and composite materials, helping prevent clogging and heat buildup during deep cuts.
• Hexagonal Shank Design - the hex shank locks securely in standard drill chucks and prevents slipping under torque, giving the operator better control and consistent hole accuracy.
• Right-Hand Rotation - compatible with conventional corded drills, cordless drills, and drill presses running standard right-hand rotation, making it easy to integrate into existing tool setups without adapters.
• Multi-Material Capability - a single saw cuts wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles, reducing the number of specialized blades a crew needs to carry on the job site.

Why This Product

• For contractors working across mixed-material wall and floor assemblies, this TCT hole saw eliminates the need to swap between multiple blades - one tool handles plasterboard, wood framing, and soft masonry in sequence without stopping.
• The 60mm cutting depth makes this 44mm hole saw a practical choice for cutting through thick substrates such as doubled framing members or block walls, where shorter-depth saws would fail to complete the cut.
• Carbide-tipped (TCT) construction gives this hole saw a meaningful durability advantage over standard high-speed steel saws when cutting abrasive materials like bricks, aerated concrete, and fiber-reinforced laminates.
• The hexagonal shank and right-hand rotation mean this saw works directly with the corded drills, cordless drills, and drill presses already on most job sites - no special arbors or adapters required beyond what is already in use.
