Product Description
The CMT Contractor Rabbeting Bit - 1 1/4" Diameter x 1/2" Cutting Height with 1/4" Shank is a precision-ground router bit engineered for clean, consistent rabbet cuts in woodworking and millwork applications. Designed for use in handheld routers, router tables, and CNC routing machines, this two-flute carbide-tipped bit excels at creating inset doors, drawer fronts, and re-grooved window frames that accept glass panels. The anti-kickback body geometry and heat-treated shank deliver controlled, repeatable cuts in solid hardwood, softwood, plywood, MDF, and a wide range of composite materials. A bottom bearing is included, making it ready to use straight out of the box for edge rabbeting and panel joinery tasks.
Key Features
- Two carbide-tipped cutting edges - dual flutes provide balanced, smooth material removal and a cleaner finished surface on cabinet backs, door stops, and frame rebates.
- Anti-kickback design - limits the amount of material each pass can remove, reducing the risk of sudden bit grab and giving the operator greater control, especially in freehand routing.
- Heat-treated shank and body - hardened steel construction resists deflection and extends service life even under repeated heavy use in production environments.
- Bottom bearing included - the bearing rides along the workpiece edge to guide the cut at a precise depth, eliminating the need for a fence for many common rabbeting tasks.
- Right-hand (RH) rotation - standard rotation compatible with virtually all handheld routers and router tables, so no special setup is required.
- 1/4" shank - fits routers equipped with a 1/4" collet, giving versatility for compact trim routers as well as full-size router tables.
- Hardwood (HW) carbide material - the carbide grade is suited for cutting solid hardwoods, softwoods, plywood, MDF, chipboard, laminates, melamine, and plastics without rapid edge degradation.
Why This Product
- Purpose-built for inset door and drawer front construction - the 1 1/4" diameter and 1/2" cutting height produce a rabbet sized for common cabinetmaking joinery in a single pass.
- Anti-kickback geometry makes this bit a practical choice for operators who need consistent results on production runs or repetitive edge cuts without constant fence adjustments.
- The included bottom bearing means the bit is fully operational immediately, removing the need to source a separate guide bearing before starting a project.
- With a 1/4" shank and right-hand rotation, this bit works with the widest range of consumer and contractor-grade routers, from compact trim routers to router table setups.
