CMT Rabbeting Bit with Bearing - 1-3/8" Diameter, 1/2" Cutting Height, 1/2" Shank is a precision router bit engineered for fast, accurate rabbet joinery in woodworking applications. Built by CMT with a 2-flute tungsten carbide-tipped cutting head, this rabbeting bit excels at producing inset doors, drawer fronts, strong rabbet joints, tongue and groove joints, and cabinet back panel recesses. The included bearing guide rides along the workpiece edge to control the cut width, delivering repeatable results whether you are working at a router table, with a handheld router, or on a CNC routing machine.

Key Features

• Carbide-Tipped (HW) Cutting Edges - tungsten carbide-faced teeth maintain a sharp edge through extended production runs in hardwood, softwood, sheet goods, and composite panels, reducing the frequency of bit changes and downtime.
• 2-Flute Design - dual cutting flutes balance chip evacuation and cut quality, producing smooth rabbet shoulders with minimal tearout for cleaner fits in joinery and frame-and-panel work.
• Precision Bearing Guide - the guide bearing registers directly against the workpiece edge to set the rabbet width accurately, eliminating the need for a fence on freehand cuts and keeping repeat cuts consistent.
• 1/2" Shank Diameter - a full 1/2" shank seats securely in heavy-duty router collets, reducing vibration and deflection during deep rabbeting cuts for a cleaner, truer result.
• Right-Hand Rotation - standard RH rotation is compatible with virtually all handheld routers, router tables, and CNC spindles, making this bit a straightforward drop-in for most shops.
• 1-3/8" Cutting Diameter - the generous cutting diameter allows for a wide rabbet in a single pass, speeding up production of cabinet backs, door stops, and panel joinery without multiple repositioning steps.
• 1/2" Cutting Height (12.7 mm) - accommodates standard rabbet depths used in cabinet construction and frame joinery, matching common material thicknesses for back panels and drawer bottoms.

Why This Product

• For shops producing inset cabinet doors and drawer fronts, the bearing-guided 1-3/8" cutting diameter delivers a consistent, repeatable rabbet in a single router pass - cutting setup time and improving throughput on production runs.
• The 2-flute tungsten carbide construction handles a wide range of materials - from solid hardwood and softwood to plywood, MDF, melamine, and plastic - making this one bit capable of covering multiple project types without swapping tools.
• With a 1/2" shank and right-hand rotation, this bit is engineered for compatibility with full-size router tables and handheld routers alike, giving woodworkers flexible deployment across different machine setups in the same shop.
• The bearing guide design removes the guesswork from freehand rabbeting cuts, registering directly against the workpiece so the rabbet width stays accurate even when routing curved or irregular edges.
