CMT Bead and Bull Nose Bit - 7/8" Diameter x 3/4" Cutting Height, 1/8" Radius, 1/2" Shank is a precision router bit from CMT designed to cut elegantly rounded bead and bull nose profiles on wood edges in a single pass. Whether you are profiling stair treads, window sills, shelves, or furniture components, this 2-tooth carbide-tipped bit delivers a clean, full-round edge contour with a 1/8" radius. Built for router table use, it offers consistent, repeatable results on solid hardwood, softwood, sheet goods, and engineered wood products.

Key Features

• Bead and Bull Nose Profile in One Pass - cuts a complete rounded bead edge contour without multiple setups, saving time and improving consistency on stair treads, window sills, and shelving edges.
• 7/8" Cutting Diameter with 1/8" Radius - produces a precise, proportionate bull nose or bead profile sized for smaller stock edges and decorative detail work.
• 3/4" Total Cutting Height - accommodates standard shelf and trim stock thickness, allowing the full profile to be routed in a single table pass.
• 1/4" Secondary Cutting Height (I1) - the additional cutting zone adds profile versatility when working with thinner workpieces or partial-depth bead applications.
• 1/2" Shank Diameter - the larger shank provides a more secure grip in the router collet, reducing vibration and improving cut quality compared to smaller shank sizes.
• 2-Tooth Hardwood Carbide (HW) Construction - dual flutes made from industrial-grade carbide deliver sharp, clean cuts in hardwood, softwood, MDF, and plywood while extending cutting life.
• Right-Hand (RH) Rotation - standard right-hand rotation is compatible with the vast majority of router table setups, making this bit a straightforward drop-in addition to any shop.
• 2 1/4" Total Length - compact overall length keeps the bit stable in the collet and reduces deflection during the cut, contributing to a cleaner finished edge.
• Router Table Use with Fence - engineered specifically for router table operation with a fence, ensuring controlled feed direction and consistent profile depth across the workpiece.

Why This Product

• Produces an elegant rounded bead or bull nose edge profile on stair treads, window sills, and shelves in a single router table pass - eliminating the need for multiple bits or secondary sanding operations to achieve a finished look.
• The 1/8" radius profile is ideally scaled for decorative bead work on narrower stock, and CMT notes that using a cutter with a bead diameter wider than the stock thickness adds an especially refined finishing touch to shelf and sill edges.
• With a 1/2" shank and 2-tooth hardwood carbide construction, this bit is built for the stability and cutting performance that router table work demands - handling hardwoods, softwoods, plywood, and MDF without sacrificing edge quality.
• At 2 1/4" total length with a 3/4" cutting height, the bit is appropriately sized for standard trim and shelf stock, keeping the setup simple and the results consistent across repeated production runs.
