Product Description
The CMT Contractor Mortising Bit with a 1/2 in. diameter and 1/4 in. shank is a professional-grade carbide router bit engineered for precise flat-bottom mortise cuts in a wide range of wood and composite materials. Designed for hinge mortising, lock pocket routing, and slot mortising applications, this 2-tooth right-hand rotation bit delivers clean results with minimal tearout - making it a reliable choice for cabinetmakers, carpenters, and woodworkers who demand accuracy in every pass.
Key Features
- Hi-Density carbide cutting edges - provide good performance in mortising applications, eliminating splintered edges and rough bottoms so you spend less time sanding and cleaning up cuts.
- Works well on natural wood and wood composites - versatility across solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic means one bit handles a broad range of project materials.
- 2-flute (2-tooth) design with right-hand rotation - balanced cutting action promotes smooth chip evacuation and reduces heat buildup during mortise routing passes.
- 1/4 in. shank diameter - compatible with a wide range of handheld routers and router tables that accept standard 1/4 in. collets, making this bit highly accessible for most woodworking setups.
- 1/2 in. cutting height with a 1/2 in. cutting diameter - produces a precisely sized mortise slot in a single pass, matching common hinge and hardware mortise depth requirements without repeated adjustments.
- Compact 2 in. total length - keeps the bit stable and reduces deflection during plunge and horizontal mortise cuts, improving accuracy and repeatability.
Why This Product
- Purpose-built for clean mortise routing - the hi-density carbide cutting edges are specifically selected to eliminate the splintered edges and rough bottoms that commonly result from using general-purpose bits in mortising applications.
- Broad material compatibility - because it works well on both natural wood and wood composites, this bit adapts to cabinet shop production environments where material types vary from job to job.
- Fits standard 1/4 in. collet routers - the 1/4 in. shank makes this bit immediately usable with most handheld routers, router tables, and CNC routing machines without requiring additional adapters or collet changes.
- Matched 1/2 in. diameter and 1/2 in. cutting height - the cutting geometry is sized to match common hardware mortise dimensions for hinges and lock plates, reducing setup time and improving fit accuracy on finish woodworking projects.

Frequently Asked Questions
What materials can this mortising bit cut?
This bit works well on natural wood and wood composites. Compatible materials include solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic.
What machines are compatible with this 1/4 in. shank mortising bit?
The 1/4 in. shank is compatible with handheld routers, router tables, and CNC routing machines equipped with a standard 1/4 in. collet.
What size mortise does this bit produce?
This bit cuts a mortise slot that is 1/2 in. wide (cutting diameter) and up to 1/2 in. deep (cutting height), making it well suited for hinge mortising and standard lock pocket applications.
Why does this bit produce cleaner results than a standard spiral bit in mortising applications?
The hi-density carbide cutting edges are specifically designed for mortising work, eliminating splintered edges and rough bottoms that can occur when general-purpose bits are used for flat-bottom mortise cuts in wood and composite materials.
