CMT Mortising Bit - 3/4" Diameter x 3/4" Cutting Height, 1/4" Shank is a precision-engineered router bit designed for clean, flat-bottom mortise cuts in solid wood, plywood, MDF, and a wide range of wood composites. Built by CMT with thick carbide tips and a negative shear angle, this 2-flute hinge mortising bit delivers splinter-free results and smooth mortise bottoms every time - whether you're routing hinge pockets, lock mortises, or template-guided sign work. The included top bearing guide makes it equally at home on a handheld router, a router table, or a CNC routing machine.

Key Features

• Thick Carbide Tips (HW - Hard Metal/Tungsten Carbide) - provide extended cutting life and consistent edge retention through dense hardwoods and abrasive composites, reducing the need for frequent bit replacement.
• Negative Shear Angle Design - pulls cut material downward during routing, eliminating splintered edges and producing a clean, flat mortise bottom that requires little to no cleanup.
• 2-Flute (2-Tooth) Configuration - balances cutting speed and surface finish, giving you efficient material removal while keeping the mortise walls smooth and dimensionally accurate.
• Top Bearing Guide Included - allows the bit to follow a template or pattern precisely, making it an ideal tool for sign making, hinge template routing, and repeatable production work.
• Right-Hand (RH) Rotation - compatible with the vast majority of handheld routers, router tables, and CNC machines, ensuring straightforward installation and predictable cutting direction.
• 1/4" Shank - fits a wide range of router collets, providing broad machine compatibility for both hobbyist and professional setups without requiring an adapter.
• 3/4" Cutting Diameter x 3/4" Cutting Height - produces a mortise slot that is perfectly proportioned for standard hinge mortising and loose-tenon joinery in a single pass, saving setup time.

Why This Product

• The negative shear angle design directly solves the most common mortising frustration - splintered edges and rough bottoms - delivering a finished mortise that fits cleanly without hand-paring or sanding.
• The top bearing guide makes this bit a dual-purpose tool: use it for hinge pocket routing with a hinge template and then switch to freehand sign making or pattern work without changing bits.
• Thick carbide tips mean this bit handles not just natural solid hardwood and softwood but also demanding wood composites like MDF, chipboard, melamine, and laminates - materials that dull standard bits quickly.
• With a 1/4" shank and right-hand rotation, this bit slots into virtually any router collet setup already in the shop, making it an accessible upgrade without the need for specialized equipment.
