CMT Bead and Bull Nose Bit by CMT is a precision-ground carbide-tipped router bit engineered to produce elegantly rounded bead and bull nose edge profiles in a single pass. With a 1/2 in. radius, 1 3/4 in. cutting diameter, and 1 5/8 in. cutting height, this bit is purpose-built for shaping stair treads, window sills, shelving edges, and furniture components where a smooth, full-round or semi-round bead finish is required. Whether you are profiling solid hardwood on a router table or dressing up shelf stock, this two-flute right-hand rotation bit delivers clean, consistent results that elevate the finished look of any woodworking project.

Key Features

• Hardwood (HW) Carbide Tips - industrial-grade carbide cutting edges stay sharp longer through dense hardwoods, composites, and sheet goods, reducing the frequency of bit replacement and keeping cuts clean over extended use.
• 2-Flute Design - dual cutting edges produce a smoother surface finish on each pass and allow for efficient chip clearance, resulting in less tear-out on profiled edges.
• 1/2 in. Radius Bead and Bull Nose Profile - creates a precisely shaped full-round or semi-round bead edge in one pass, eliminating the need for multiple setups or secondary sanding to achieve a refined profile on stair treads, window sills, and shelves.
• 1/2 in. Shank Diameter - the heavy-duty 1/2 in. shank provides greater rigidity and reduced vibration compared to smaller shanks, resulting in better cut accuracy and a safer, more controlled routing experience.
• Right-Hand Rotation - standard RH rotation is compatible with the vast majority of router table setups, making this bit straightforward to integrate into existing workflows without special tooling.
• Router Table with Fence Required - designed for controlled router table use with a fence, ensuring repeatable, accurate profile cuts and a safer working environment when shaping edges.
• Bead Width Versatility - using a cutter with a bead diameter wider than the stock thickness adds a final decorative touch, giving woodworkers flexibility in the finished appearance of profiled edges.

Why This Product

• Produces complete bead and bull nose edge profiles in a single router table pass - saving setup time and delivering consistent results on stair treads, window sills, and shelf edges without multiple tool changes.
• The 1 5/8 in. cutting height accommodates thicker stock common in stair tread and sill applications, making this bit suited for substantial workpieces where smaller bits fall short.
• Two carbide flutes working together mean smoother finished surfaces directly off the bit, reducing or eliminating the hand-sanding often required after profiling with lower-quality tooling.
• The 1/2 in. shank and robust overall length of 3 1/8 in. provide the stability needed for large-radius profile cuts, where bit flex and chatter can ruin the finished edge on hardwood and engineered wood alike.
