Product Description
CMT Mortising Router Bit - 1-1/4" Diameter x 1/2" Cutting Height, 1/2" Shank is a professional-grade hinge mortising bit engineered for routers and CNC machines where clean, flat-bottom mortise slots are essential. Built with thick carbide tips and a negative shear angle design, this CMT bit delivers splinter-free edges and smooth mortise bottoms across solid hardwood, softwood, and wood composites alike. Whether you are cutting hinge pockets, lock mortises, or working from a template for sign-making applications, this bit brings precision and reliability to every pass.
Key Features
- Thick Carbide Tips (HW grade) with negative shear angle design - produce flawless, flat-bottom mortises with no splintered edges, eliminating the need for additional cleanup work on natural wood or wood composites.
- Top bearing guide included - allows the bit to follow a template precisely, making it the right tool for sign making, hinge template routing, and repeatable pattern work where consistent results are critical.
- 2-flute (2-tooth) configuration - balances chip evacuation speed with surface finish quality, keeping cuts smooth and reducing heat buildup during mortise routing operations.
- Right-hand (RH) rotation - compatible with standard handheld routers, router tables, and CNC routing machines without requiring any special tooling setup.
- 1/2" shank diameter - provides a secure, vibration-resistant connection in 1/2" collet routers, improving accuracy and reducing chatter during deeper cuts.
- 1-1/4" cutting diameter with 1/2" cutting height - sized specifically for common hinge mortise dimensions, allowing a precise fit for standard hardware installation in one clean pass.
Why This Product
- Engineered for clean hinge mortising - the negative shear angle combined with thick carbide tips produces flat, smooth-bottomed mortises on both natural wood and wood composites, so hinges and hardware seat flush the first time without extra chiseling or sanding.
- Template work made repeatable - the top bearing guide lets you follow a hinge template or sign-making pattern with accuracy on every piece, making this bit a practical choice for high-volume or production-style routing setups.
- Broad material compatibility - suited for solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic, so the same bit handles a wide range of shop projects without switching tools.
- Versatile machine compatibility - works in handheld routers, router tables, and CNC routing machines with a standard 1/2" collet, making it easy to integrate into an existing workflow without special adapters or setup changes.

Frequently Asked Questions
What types of materials can this mortising bit cut?
This bit is suited for solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic - making it a versatile choice for furniture making, cabinet installation, and general woodworking applications involving both natural wood and wood composites.
Does this bit include a bearing guide for template work?
Yes. This CMT mortising bit comes complete with a top bearing guide, allowing it to follow hinge templates and jigs accurately. This makes it especially useful for production hinge mortising, sign making, and any application where consistent, repeatable cuts are required.
What router shank size is required to use this bit?
This bit uses a 1/2" shank diameter, which fits 1/2" collet routers. It is compatible with handheld routers, router table setups, and CNC routing machines equipped with a standard 1/2" collet.
What is the cutting capacity of this mortising bit?
The bit has a cutting diameter of 1-1/4" and a cutting height of 1/2", with a total length of 2-1/8". This sizing is well suited for standard hinge mortises and lock pocket routing where a precise, flat-bottom slot is needed for flush hardware installation.
