The CMT Contractor Bull Nose Bit - 13/16" Diameter, 23/32" Radius, 1/4" Shank is a convex edge routing bit engineered for cutting shallow bull nose profiles and producing a soft, gently rounded edge on natural wood and wood-based materials. Designed for craftsmen who demand clean, repeatable edge profiles on furniture, shelving, cabinetry, and countertops, this 2-flute carbide-tipped bit delivers smooth, accurate results in solid hardwood, softwood, MDF, and engineered sheet goods. The right-hand rotation and anti-kickback body geometry make it a dependable choice for both handheld router and router table use.

Key Features

• Carbide-Tipped Cutting Edges (HW Material) - industrial-grade hard metal carbide tips stay sharp longer through dense hardwoods and abrasive composites, reducing downtime for sharpening or replacement.
• Two Cutting Flutes - dual cutting edges distribute the cutting load evenly, producing a cleaner surface finish and extending the service life of the bit in continuous production use.
• Anti-Kickback Design - the body geometry limits the depth of cut per pass, reducing the risk of sudden kickback and improving operator safety and cut consistency.
• Heat-Treated Shank and Body - heat treatment increases the structural integrity of the 1/4" shank and body, allowing the bit to handle routing stresses without bending, warping, or premature fatigue.
• 23/32" Radius Profile - produces a precise, shallow bull nose convex edge that softens sharp corners on wood edges, giving furniture, shelves, and trim a refined, finished appearance.
• 1/4" Shank Diameter - fits standard 1/4" collet routers, making this bit compatible with a wide range of handheld routers and router tables without adapters.
• Right-Hand Rotation - standard RH rotation is compatible with the vast majority of routers, ensuring straightforward drop-in use with no special setup required.

Why This Product

• The 23/32" radius profile is purpose-built for shallow bull nose edge work - ideal for woodworkers who need a gentle, rounded convex edge without committing to a full round-over, giving projects a softer, more refined look on natural wood and wood-based panels.
• The anti-kickback body design actively limits each pass depth, making this bit a safer option for both experienced professionals and woodworkers who want greater control when routing edge profiles on furniture and shelving.
• Hard metal (HW) carbide tips combined with a heat-treated shank and body mean the bit holds up through repeated use in demanding materials like dense hardwoods and engineered composites - reducing the frequency of bit changes on busy job sites or in high-volume shop environments.
• The 1/4" shank makes this bit accessible to a broad range of router setups, from compact trim routers to full-size router tables, so it integrates easily into an existing tool kit without requiring a new collet or adapter.
