CMT Rabbeting Bit with Bearing - 1 1/4" Diameter, 1/2" Cutting Height, 3/8" Depth, 1/2" Shank is a precision carbide-tipped routing bit designed for cutting clean, accurate rabbets along board edges. Built by CMT 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, rabbet joinery, and tongue and groove milling - tasks that are otherwise time-consuming and difficult with standard tooling. The hardmetal (HW) carbide construction and 2-flute design deliver smooth, repeatable cuts in a wide range of wood-based and composite materials.

Key Features

• Hardmetal (HW) Carbide Cutting Material - industrial-grade carbide edges hold their sharpness through extended production runs, reducing downtime for resharpening and maintaining cut quality across repeated passes.
• Bearing Guide Included - the bearing registers directly against the workpiece edge to control the rabbet depth automatically, eliminating the need for a fence and delivering consistent results without manual adjustment between passes.
• 2-Flute Design - dual cutting edges increase the feed rate potential and produce a cleaner surface finish than single-flute alternatives, making it well suited for finish-grade cabinet and frame work.
• 1/2" Shank Diameter - the large-diameter shank seats securely in router collets, reduces bit deflection under load, and improves cut accuracy in both handheld and table-mounted routing setups.
• Right-Hand Rotation - matches the standard rotation direction of virtually all routers, so the bit installs and runs without any special collet or spindle configuration.
• 3/8" Rabbet Depth (9.53mm Cutting Depth) - a defined cutting depth that suits common cabinet back panel grooves, door stop rabbets, and panel joinery applications without requiring a depth stop change mid-job.
• 1/2" Cutting Height - provides adequate engagement with the workpiece edge to produce a clean, full rabbet shoulder in a single pass on standard stock thicknesses.
• 2-13/32" Total Length - compact enough for handheld router use while providing sufficient reach for router table setups, including use with featherboards and push blocks.

Why This Product

• For woodworkers and cabinet makers producing inset doors and drawer fronts, this rabbeting bit delivers fast, accurate results - what CMT describes as quickly producing inset doors and drawer fronts that are otherwise time-consuming to fit by other methods.
• The bearing-guided design removes the guesswork from rabbet depth: once set, the bearing rides the edge and the cut is repeatable piece after piece, which is critical in production runs where consistency matters.
• The 1/2" shank is the preferred choice for router table work and heavy-duty handheld routing because it significantly reduces chatter and deflection compared to smaller shanks, resulting in a cleaner rabbet shoulder.
• The hardmetal carbide construction means this bit handles not just solid hardwood and softwood but also plywood, MDF, chipboard, laminates, melamine, and plastic - making it a single versatile tool for mixed-material shop environments.
