CMT Beading Bit with Bearing - 5/8" Diameter, 1/2" Cutting Height, 1/16" Radius, 1/4" Shank is a precision decorative edge-profiling router bit from CMT, designed to cut a classic bead profile along wood edges. Unlike a standard roundover bit, this beading bit uses a smaller bearing that produces a delicate inset at the base of the cut - giving woodworkers an extra ornamental detail that elevates furniture edges, cabinet faces, and trim work. The 2-tooth hardmetal carbide construction delivers clean, consistent results in solid hardwood, softwood, and composite materials alike, making it a go-to choice for both handheld routers and router table setups.

Key Features

• Hardmetal (HW) Carbide Cutters - industrial-grade carbide material holds a sharp edge longer, reducing the frequency of bit changes and keeping cuts smooth through demanding routing sessions.
• 2-Tooth (2-Flute) Design - dual cutting edges share the workload evenly, producing a balanced, chatter-free bead profile and a cleaner surface finish on each pass.
• Ball-Bearing Guide - the integrated bearing rides along the workpiece edge to maintain a precise, repeatable depth of cut without the need for a fence, making freehand edge routing straightforward and consistent.
• 1/16" Radius Bead Profile - the small, delicate inset at the base of the cut adds a refined decorative accent that distinguishes beading from a plain roundover, giving finished pieces a more polished, traditional appearance.
• 1/4" Shank - fits a wide range of handheld routers and router tables equipped with 1/4" collets, offering broad compatibility for hobbyist and professional setups.
• Right-Hand Rotation - standard RH rotation is compatible with the vast majority of router motors, ensuring straightforward installation and safe operation.
• 5/8" Cutting Diameter with 1/2" Cutting Height - the proportions of this bit allow it to profile edges efficiently in a single pass, saving time when working on longer runs of trim or cabinetry.
• Compact 2 1/16" Total Length - the overall length keeps the bit stable in the collet with minimal overhang, reducing vibration and improving cut accuracy.

Why This Product

• The integrated bearing guide eliminates the guesswork of fence setup for edge work - ideal for woodworkers who want consistent bead profiles on curved or straight edges without additional jigs or fixtures.
• The 1/16" radius bead profile creates a subtle yet distinctive decorative inset that a standard roundover bit cannot replicate, making this the right choice when a project calls for traditional furniture or cabinet detailing.
• The hardmetal carbide construction with 2 cutting flutes handles both solid hardwood and softer composite materials, giving this single bit broad versatility across a wide range of woodworking projects.
• The 1/4" shank size makes this bit accessible for compact handheld routers as well as full-size router tables, so it works across the tools most woodworkers already own.
