CMT Beading Bit with Bearing - 1 1/2" Diameter, 3/4" Cutting Height, 1/2" Radius, 1/2" Shank by CMT is a precision router bit designed to produce elegant bead profiles along wood edges. Similar to a roundover profile, the beading cut adds a refined decorative detail by incorporating a small inset at the base of the rounded edge - giving woodworkers an extra ornamental option for furniture, cabinetry, and architectural millwork. With a 1/2" radius and a hardmetal (HW) carbide cutting edge, this bit delivers clean, consistent results on a wide range of solid wood and sheet goods applications.

Key Features

• Beading Profile with Inset Detail - unlike a standard roundover, the smaller bearing on this bit creates a delicate inset at the base of the cut, giving you an additional decorative profile option without changing bits or setups.
• Hardmetal (HW) Carbide Cutting Material - industrial-grade carbide construction stays sharp longer and handles demanding materials including hardwoods, softwoods, plywood, and MDF without premature dulling.
• Ball-Bearing Guide Included - the integrated bearing rides along the workpiece edge to control cut depth automatically, producing uniform bead profiles pass after pass without the need for additional guides or fences.
• 1/2" Shank Diameter - a full 1/2" shank reduces vibration and flex during the cut, improving edge quality and reducing chatter on both handheld routers and router tables.
• 2-Flute Right-Hand Rotation Design - two cutting edges with right-hand rotation provide balanced cutting action, smoother surface finish, and efficient chip evacuation for cleaner profiles.
• 1/2" Radius Profile - a generous 1/2" radius produces a prominent, well-defined bead that reads clearly on furniture edges, frame profiles, and panel details.
• 2-9/16" Total Length - compact overall length keeps the bit stable and balanced in the collet, reducing runout and improving accuracy on detailed decorative work.

Why This Product

• The beading profile - with its distinctive inset at the base of the rounded edge - offers a more refined decorative result than a plain roundover, making this bit the right choice when furniture or cabinet edges need a classic, traditional detail.
• The integrated bearing guide eliminates guesswork: it references directly off the workpiece face, keeping cut depth consistent across the full length of the edge without requiring a router table fence or manual depth adjustments.
• The 1/2" shank is the largest standard collet size available on most routers and router tables, meaning this bit runs with less vibration and greater stability than smaller-shank alternatives - important when routing decorative profiles where surface quality matters.
• Hardmetal carbide (HW) construction means the cutting edges hold up through extended production runs on hardwood furniture parts, softwood moldings, and engineered sheet goods without requiring frequent resharpening.
