CMT Bead and Bull Nose Bit - 1 in. Diameter, 7/8 in. Cutting Height, 3/16 in. Radius, 1/4 in. Shank by CMT is a precision-ground, 2-flute router bit engineered to produce elegantly rounded bead and bull nose edge profiles on stair treads, window sills, shelves, and furniture components in a single pass. Crafted from HW (tungsten carbide) with right-hand rotation, this bit delivers smooth, repeatable profiles on hardwood, softwood, and sheet goods alike. Whether you need a classic beaded edge on cabinetry shelving or a refined bull nose on a window sill, this router bit handles the work cleanly and efficiently at the router table.

Key Features

• 2-Flute Tungsten Carbide (HW) Construction - two cutting edges made from industrial-grade hard metal deliver clean, smooth profiles with reduced chatter, extending cutting life between sharpenings.
• 3/16 in. Radius Bead and Bull Nose Profile - creates a full, elegantly rounded bead edge in a single router table pass, eliminating the need for multiple setups or secondary sanding steps.
• 1/4 in. Shank Diameter - fits a wide range of standard 1/4 in. collet routers and router tables, making this bit accessible for hobbyists and professional woodworkers with common equipment.
• 1 in. Overall Cutting Diameter - sized to allow the bead diameter to exceed typical stock thickness on window sills and shelves, producing a pronounced, furniture-quality profile.
• 7/8 in. Total Cutting Height with 3/8 in. Upper Cutting Height - generous cutting depth handles standard dimensional lumber and sheet stock in a single setup without repositioning the workpiece.
• Right-Hand (RH) Rotation - compatible with the standard rotation direction of virtually all handheld routers and router table spindles, ensuring correct chip ejection and a clean finished surface.
• 2-1/8 in. Total Length - compact overall length keeps the bit stable and well-supported in the collet, reducing vibration and improving profile accuracy.
• Router Table Use with Fence - designed specifically for use on router tables equipped with a fence, providing controlled, repeatable cuts on stair treads, sills, and shelf edges with consistent results every time.

Why This Product

• One-pass edge profiling saves time - the 3/16 in. radius bead and bull nose geometry profiles the full edge of a workpiece in a single router table pass, reducing setup time and finishing labor on furniture, shelving, and millwork projects.
• Versatile finishing bit for common architectural details - equally suited to stair tread nosings, window sill edges, and shelf fronts, this bit covers a broad range of interior woodworking and finish carpentry applications from a single tool.
• Designed for decorative effect beyond stock thickness - CMT specifically designed this bit so that the bead diameter can exceed the stock thickness, allowing woodworkers to add an elevated, furniture-quality finishing touch to thinner shelving and sill material.
• HW carbide construction supports extended production use - tungsten carbide cutting edges maintain sharpness through high-volume runs on hardwood and softwood, making this bit a practical investment for shops producing cabinetry, furniture, or custom millwork in quantity.
