CMT Rabbeting Bit with Bearing - 1-3/8" Diameter, 1/2" Cutting Height, 1/4" Shank is a precision tungsten carbide router bit engineered for fast, accurate rabbet joinery in wood and wood-composite materials. Designed for use in handheld routers, router tables, and CNC routing machines, this right-hand rotation bit makes quick work of inset door fitting, drawer front construction, cabinet back panel installation, and tongue-and-groove joinery. The included bearing guide ensures repeatable, controlled cuts along board edges - reducing setup time and delivering consistent results across a wide range of woodworking and millwork applications.

Key Features

• Tungsten Carbide (HW) Cutting Material - industrial-grade carbide maintains a sharp cutting edge longer than standard steel, reducing the frequency of sharpening or bit replacement during heavy production use.
• 2-Flute Design - two cutting edges provide smooth stock removal and a cleaner finished surface on rabbet shoulders, minimizing tearout on solid hardwood, softwood, plywood, MDF, and laminates.
• Bearing Guide Included - the piloted bearing follows the workpiece edge to control rabbet width automatically, eliminating the need for fences or edge guides and allowing freehand routing along straight or curved profiles.
• 1/4" Shank - fits a wide range of compact handheld routers and laminate trimmers, making this bit accessible to hobbyists and professionals who work with lighter-duty routing equipment.
• 1-3/8" Cutting Diameter - provides sufficient diameter to produce clean, full-depth rabbets for cabinet backs, frame-and-panel assemblies, and door stop profiles in a single pass.
• 1/2" Cutting Height - accommodates standard rabbet depths needed for most door, drawer, and panel joinery applications without requiring multiple depth adjustments.
• Right-Hand Rotation (RH) - compatible with all standard router spindle directions, requiring no special setup or tooling modifications.
• 2-11/32" Total Length - compact overall length keeps the bit stable and reduces vibration during cutting, contributing to cleaner cuts and longer bearing life.

Why This Product

• The bearing-guided design eliminates the need for a router table fence or separate edge guide - making it practical to cut accurate rabbets freehand on assembled cabinet frames, door panels, and curved workpieces where a fence cannot be used.
• With a 1/4" shank, this bit is compatible with compact and trim routers that cannot accept larger 1/2" shank tooling, expanding its usability for cabinetmakers and woodworkers who rely on lighter routing equipment for detail work.
• The carbide cutting faces handle a broad range of materials - from solid hardwood and softwood to plywood, MDF, chipboard, melamine, and plastic - making this a single versatile tool capable of handling varied production runs without switching bits.
• At 1/2" cutting height and 1-3/8" diameter, this bit is proportioned for the most common rabbet joinery tasks - inset doors, drawer fronts, panel backs, and tongue-and-groove joints - so woodworkers can complete typical cabinet and furniture work efficiently without needing multiple specialized bits.
