CMT Round Nose Set (3-Piece) with 1/4 in. Shank - this three-piece router bit set from CMT delivers the three most practical round nose (core box) radii in a single value-packed collection. Designed for right-hand rotation and compatible with 1/4 in. shank routers, these carbide-tipped bits rout smooth, semi-circular coves, decorative grooves, and fluted profiles with consistent precision. Whether you are working on veining details, decorative inlays, or rounded channel work in solid wood, sheet goods, or plastic, this set equips you with the radius options you actually reach for most - 1/8 in., 1/4 in., and 3/8 in. - without the need to purchase each profile separately.

Key Features

• CMT Orange Shield Non-Stick Coating - prevents the bit from heating up during extended cuts, reduces pitch and resin buildup on the flutes, and protects against corrosion, extending overall tool life and reducing cleanup time between uses.
• SinterHIP Industrial Chrome Carbide - carbide processed via Hot Isostatic Pressing (HIP) eliminates internal voids and micro-fractures that cause material failure, resulting in a harder, more consistent cutting edge that stays sharp through demanding routing sessions.
• Tri-Metal Brazing (Silver-Copper-Silver) - a three-layer brazing method bonds the carbide tips to the body with exceptional strength, protecting against weld failure when routing harder hardwoods or composite materials.
• Anti-Kickback Design - controls depth of cut and minimizes kickback risk, giving you safer, more controlled passes especially on a handheld router or router table.
• 2-Flute Carbide-Tipped Construction - two cutting teeth produce a clean, balanced cut and efficient chip ejection, reducing heat buildup and leaving a smooth surface finish in the routed groove.
• 1/4 in. Shank Compatibility - fits the widest range of compact and full-size routers, making this set versatile for handheld routing, router table use, and CNC applications.
• Right-Hand Rotation - matches the standard rotation direction of virtually all commercially available routers, ensuring correct performance right out of the box.
• 3-Piece Set Format - three of the most widely used round nose radii (1/8 in., 1/4 in., 3/8 in.) included together, so you have the full range of common cove profiles available without sourcing individual bits separately.

Why This Product

• Covers the most practical round nose radii in one purchase - with 1/8 in., 1/4 in., and 3/8 in. profiles all included, this set handles the majority of fluting, veining, and decorative groove work without requiring separate bit orders for each profile.
• Built for longevity with SinterHIP carbide and Orange Shield coating - the combination of HIP-processed carbide and a non-stick protective coating means less frequent sharpening and replacement, reducing long-term tooling costs.
• Works across a wide material range - from solid hardwood and softwood to MDF, plywood, laminates, melamine, chipboard, and plastic, these bits adapt to the materials you already work with most.
• Compatible with handheld routers, router tables, and CNC machines - the 1/4 in. shank and right-hand rotation make this set a practical addition to multiple shop setups, not just a single dedicated machine.
