CMT Beading Bit with Bearing - 1" Diameter, 1/4" Radius, 1/2" Shank is a precision router bit from CMT designed to cut elegant bead profiles along wood edges. Beading bits are similar to a roundover profile, but the smaller bearing creates a delicate inset at the base of the cut, giving woodworkers an extra decorative option that sets finished pieces apart. With a 1" cutting diameter, 1/2" cutting height, and a 1/4" radius, this bit is well suited for adding refined decorative edge details to furniture components, cabinet doors, and millwork. The integrated ball-bearing guide ensures consistent, repeatable depth of cut on every pass.

Key Features

• Beading Profile with Inset Detail - unlike a standard roundover, the smaller bearing produces a delicate inset at the base of the cut, adding a secondary decorative accent that elevates edge profiles on furniture and cabinetry.
• Integrated Ball-Bearing Guide - rides along the workpiece edge to maintain a consistent cutting depth throughout the pass, reducing the need for a fence setup and improving repeatability across multiple pieces.
• 1" Cutting Diameter and 1/2" Cutting Height - provides sufficient reach to create a full bead profile in a single pass on standard solid wood edges and panels.
• 1/4" Radius - produces a proportional, graceful bead profile that works well on furniture legs, frame edges, cabinet rails, and decorative trim.
• 1/2" Shank - the larger shank diameter reduces vibration and flex during cutting, resulting in smoother cuts and improved surface finish compared to 1/4" shank bits.
• HW (Hardwood-Grade) Carbide Cutting Material - the carbide teeth are formulated to handle solid hardwoods and other demanding materials while maintaining a sharp edge over extended use.
• 2-Flute Design - two cutting edges provide a balanced cutting action, helping to minimize tearout and deliver cleaner edge profiles on each pass.
• Right-Hand Rotation - standard RH rotation is compatible with all conventional handheld routers and router tables, making this bit a straightforward drop-in for most workshop setups.
• 2-5/16" Total Length - compact enough to be used comfortably in a handheld router while still providing adequate projection for table-mounted routing applications.

Why This Product

• The beading profile is distinct from a standard roundover because the smaller bearing creates an inset at the base of the cut - meaning woodworkers get a two-element decorative edge in a single router pass, saving time versus using multiple bits.
• The 1/2" shank is the right choice for production routing or extended sessions where bit stability matters - the heavier shank reduces chatter and helps deliver consistent, smooth profiles across long runs of material.
• The integrated bearing guide lets you work without a fence on shaped or curved workpieces, making this bit practical for routing curved furniture legs, arched door rails, and other non-linear edges where a fence cannot follow the contour.
• With a 2-flute carbide construction rated for hardwood-grade cutting, this bit handles the denser species commonly used in furniture and cabinet work - such as oak, maple, and cherry - without sacrificing edge quality or requiring frequent resharpening.
