CMT Beading Bit with Bearing - 1 1/8" Diameter, 1/2" Cutting Height, 5/16" Radius, 1/4" Shank by CMT is a precision router bit designed to mill elegant decorative bead profiles along wood edges. Unlike a standard roundover bit, this beading bit uses a smaller bearing to produce a subtle inset at the base of the cut, adding a refined decorative detail to furniture edges, cabinet frames, and millwork. The 1/4" shank makes it compatible with compact handheld routers and router tables, and the right-hand rotation suits standard router operation. Whether you are routing solid hardwood for fine furniture or working with softwood trim, this bit delivers a consistent, repeatable bead profile on every pass.

Key Features

• Beading Profile with Bearing Guide - the ball-bearing pilot rides along the edge of your workpiece to control depth automatically, producing a consistent 5/16" radius bead without the need for fences or jigs on most edge-routing tasks.
• Smaller Bearing Produces an Inset at the Base of the Cut - unlike a roundover bit that blends smoothly into the face, the beading bit creates a delicate shoulder detail at the bottom of the profile, giving you an extra decorative option on cabinet doors, drawer fronts, and furniture edges.
• HW (Tungsten Carbide) Cutting Material - hard-wearing carbide teeth stay sharper longer than high-speed steel alternatives, reducing the frequency of resharpening and maintaining clean, chip-free cuts across solid hardwood, softwood, and engineered wood products.
• 2-Flute Design - two cutting edges balance chip load and heat generation, resulting in a smoother surface finish that requires less sanding and cleanup after routing.
• 1/4" Shank Compatibility - fits the 1/4" collets found on a wide range of compact and mid-size routers, making this bit accessible for woodworkers who do not own a full 1/2" shank router.
• Right-Hand Rotation - matches the standard clockwise rotation direction of virtually all handheld and table-mounted routers, so no special setup or configuration is needed.
• 2 1/16" Total Length - the overall bit length keeps the cutting geometry stable in the collet while providing enough reach to handle typical edge-profiling tasks on panels and frame stock.

Why This Product

• The bearing-guided beading profile eliminates the guesswork of freehand depth setting - the bearing controls the cut automatically, making it straightforward to achieve identical results across long runs of trim, face frame stock, or table edges.
• The 5/16" radius bead is a classic decorative detail that adds visual interest without overpowering smaller pieces - well suited for drawer fronts, cabinet rail and stile work, and furniture aprons where a subtle profile is preferred over a large cove or ogee.
• The 1/4" shank opens this bit up to a broader range of router platforms, including lighter trim routers and compact plunge routers commonly used for furniture and cabinetry detail work.
• The 2-flute carbide construction means the bit handles both ripping across grain and routing with the grain, maintaining a clean edge profile on a variety of wood species and sheet goods without excessive tear-out.
