CMT Beading Bit with Bearing - 3/4" Diameter, 1/2" Cutting Height, 1/8" Radius, 1/4" Shank is a precision carbide-tipped router bit designed to cut elegant bead profiles along wood edges. Similar in profile to a roundover bit, this beading bit uses a smaller bearing to produce a delicate inset at the base of the cut, adding a refined decorative detail to furniture edges, cabinet doors, frames, and architectural millwork. With a right-hand rotation, 2-flute design, and 1/4" shank, this bit is compatible with handheld routers and router tables suited to light-duty decorative edge work.

Key Features

• Carbide-tipped cutting edges (HW material grade) - hard-wearing carbide maintains a sharp cutting edge longer than high-speed steel, reducing the frequency of replacements and delivering cleaner cuts over extended use.
• Ball-bearing guide included - the bearing rides along the workpiece edge to control the depth of cut automatically, producing a consistent bead profile pass after pass without the need for a fence or separate depth stop.
• 1/8" radius bead profile - the smaller bearing relative to the cutter diameter creates a subtle inset at the base of the roundover, giving edges a distinct decorative bead rather than a plain roundover - useful when a more refined detail is required.
• 1/4" shank - fits standard 1/4" router collets found on compact and trim routers as well as full-size routers with a 1/4" collet, making this bit widely compatible across common workshop setups.
• 2-flute (2-tooth) design - dual cutting edges help balance the bit during rotation and provide a smoother surface finish on the profiled edge, reducing sanding time.
• Right-hand rotation - matches the standard rotation direction of virtually all routers sold in North American markets, so the bit runs correctly without any special setup.
• 2 1/16" total length - compact overall length keeps the bit stable and well-supported in the collet, contributing to reduced vibration and accurate edge profiles.

Why This Product

• The beading profile - a roundover with a small inset detail at its base - is a classic decorative option that adds visual interest to furniture edges, picture frames, cabinet rails, and trim work without requiring complex setups or specialty tooling.
• The integrated bearing guide does the depth-control work for you, keeping the profile uniform across the full length of an edge even on long workpieces - ideal for production runs or repetitive furniture joinery where consistency matters.
• At 1/4" shank diameter, this bit works with compact trim routers and handheld routers alike, giving woodworkers flexibility to use it freehand on a benchtop or mounted in a router table for guided edge profiling.
• The carbide (HW) cutting material handles solid hardwood, softwood, and engineered panels, meaning one bit covers a wide range of common cabinet and furniture materials without switching tools.
