The CMT 839.317.11 Beading Bit with Bearing is a precision-crafted carbide router bit designed to produce a classic bead profile along wood edges. Featuring a 3/8" radius, this 1/4" shank bit delivers a decorative inset at the base of the cut that sets it apart from a standard roundover - adding refined detail to furniture edges, cabinet faces, and millwork. The included ball-bearing guide rides along the workpiece to maintain a consistent cutting depth, giving woodworkers smooth, repeatable results across solid hardwood, softwood, and engineered wood materials.

Key Features

• Beading profile with inset detail - unlike a plain roundover, the smaller bearing on this bit creates a delicate inset at the base of the cut, giving edges a more decorative and refined appearance suitable for fine furniture and cabinet work.
• Ball-bearing guide included - the bearing rides along the stock to control depth automatically, eliminating the need for a fence on most edge-profiling tasks and ensuring consistent, repeatable cuts pass after pass.
• 3/8" radius cutting geometry - sized to produce a prominent yet elegant bead that reads well on furniture components, door frames, and decorative trim.
• HW (carbide) cutting material - hard-wearing carbide construction maintains a sharp edge through extended use in both solid wood and composite materials, reducing the frequency of bit changes.
• 1/4" shank diameter - compatible with a wide range of handheld routers and router tables that accept 1/4" collets, making this bit highly versatile across common woodworking setups.
• 2-flute right-hand rotation - 2 cutting edges (2 teeth) working in right-hand rotation deliver a smooth, clean cut with reduced chatter, helping produce finished edges that require minimal sanding.
• 2 1/4" total length - compact overall length keeps the bit stable during use and reduces deflection, supporting accurate, controlled edge profiles.

Why This Product

• The beading profile goes beyond a simple roundover by producing a subtle inset at the base of the cut, making it the right choice when a project calls for classic decorative detail rather than a plain eased edge.
• With a 1/4" shank, this bit works with virtually any handheld router or router table equipped with a standard 1/4" collet, so there is no need for specialized equipment to get professional-quality bead profiles.
• The bearing-guided design removes the guesswork from depth setting - the bearing controls the cut automatically, so the same clean 3/8" bead can be reproduced consistently across multiple workpieces or long production runs.
• Carbide construction (HW material) holds an edge significantly longer than high-speed steel alternatives, making this bit a practical choice for woodworkers who profile edges frequently and want a tool that holds up over time.
