CMT Beading Bit with Bearing - 1 1/2" Diameter, 3/4" Cutting Height, 1/2" Radius, 1/4" Shank by CMT is a precision router bit designed to cut decorative bead profiles along wood edges. Similar in shape to a roundover bit, the beading profile features a smaller bearing that produces a delicate inset at the base of the cut, giving woodworkers an extra decorative detail option. With a right-hand rotation, 2-flute carbide construction, and a ball-bearing guide for consistent depth control, this bit is well suited for furniture making, cabinetry, and ornamental edge work on a wide range of materials.

Key Features

• Beading profile with bearing guide - the smaller bearing relative to the cutting diameter creates a distinctive inset at the base of the bead, giving edges a refined decorative detail that a standard roundover bit cannot produce.
• 1/2" radius cutting profile - delivers a consistent, smooth bead shape on every pass, reducing the need for hand sanding or secondary shaping after routing.
• 3/4" cutting height - provides enough depth of engagement to complete the full bead profile in a single pass on most standard stock thicknesses, improving efficiency at the router table or with a handheld router.
• 2-flute (2-tooth) design - two carbide cutting edges share the workload evenly, producing a cleaner surface finish and extending the usable life of each edge between sharpenings.
• HW (carbide) material - hard tungsten carbide cutting edges stay sharp longer than high-speed steel, making this bit suitable for hardwoods, softwoods, sheet goods, and composite materials.
• 1/4" shank diameter - fits standard 1/4" router collets found on compact trim routers and full-size routers alike, making this bit broadly compatible across common workshop tools.
• Right-hand rotation - matches the standard rotation direction of virtually all routers sold for woodworking, so the bit installs and runs without any special setup.
• 2 5/16" total length - a compact overall length keeps the bit stable in the collet and reduces vibration during cuts, contributing to cleaner results and longer bearing life.

Why This Product

• The beading profile goes one step beyond a plain roundover by adding a small inset at the base of the cut - a detail that elevates the look of furniture edges, cabinet doors, and decorative trim without requiring additional tooling or hand work.
• The ball-bearing guide follows the workpiece edge automatically, so routing depth stays consistent even as grain direction or stock thickness varies slightly - reducing waste from mis-routed pieces.
• The 1/4" shank makes this bit accessible to compact trim routers as well as full-size router tables, giving hobbyists and professionals flexibility in how and where they use it.
• Hard carbide construction (HW material) handles both solid hardwoods and engineered sheet materials, so one bit covers a broad range of everyday edge-profiling tasks without swapping between tools.
