CMT Bead and Bull Nose Bit - 1 1/8" Diameter x 1" Cutting Height, 1/4" Radius, 1/4" Shank by CMT delivers clean, full-round bead and bull nose edge profiles in a single pass, making it an ideal choice for stair treads, window sills, shelves, and furniture edges. Crafted from industrial-grade carbide (HW material), this 2-flute right-hand router bit handles solid hardwood, softwood, and sheet goods with consistent results when used on a router table with a fence. Whether you are shaping decorative shelf edges or finishing window sill profiles, this compact 1/4" shank bit brings professional-quality results to fine woodworking and millwork projects.

Key Features

• 1/4" bead radius profile - produces a precise, elegantly rounded bead or bull nose edge in one pass, eliminating the need for multiple setups or secondary sanding steps.
• 1 1/8" cutting diameter with 1 1/64" cutting height - covers a generous edge width, allowing you to shape thicker stock and achieve a complete profile without repositioning the workpiece.
• Hardwood (HW) carbide cutting tips - industrial-grade carbide maintains a sharp edge longer in dense and abrasive materials, reducing downtime for bit changes and keeping cuts smooth and clean.
• 2-flute right-hand rotation design - dual flutes distribute cutting load evenly, producing a smoother surface finish and reducing tear-out on hardwood and softwood edges.
• 1/4" shank - fits standard 1/4" router collets on a wide range of router tables, providing easy integration into existing setups without additional adapters.
• 2 1/4" total length - compact overall length keeps the bit stable at the collet, minimizing vibration and maintaining accuracy during edge profiling passes.
• Router table with fence required (except where noted) - fence-guided operation controls feed rate and lateral positioning for repeatable, consistent profiles on every workpiece.

Why This Product

• Single-pass bead and bull nose profiling - this bit shapes a complete rounded bead edge in one router table pass, saving time compared to multi-step profiling setups on stair treads, sills, and shelves.
• Wider bead than stock thickness creates a decorative accent - using a cutter with a bead diameter wider than the stock thickness adds a distinctive finished look, giving you design flexibility beyond basic edge rounding.
• Hardwood carbide at a 1/4" shank size - the HW carbide tips deliver cutting performance in solid hardwoods and composites through a 1/4" shank bit, making premium profiling accessible on compact router table setups.
• Designed for router table fence use - fence-guided operation keeps cuts controlled and workpieces stable, reducing the risk of movement mid-cut and supporting safer, more consistent results on trim and millwork applications.
