CMT 838.001.11 3 Piece Roundover Set by CMT is a professional-grade router bit set designed to deliver smooth, consistent radius edge profiles across a wide range of woodworking applications. This three-bit collection covers radii of 1/4", 3/8", and 1/2" - all driven by a 1/4" shank - giving craftsmen the flexibility to round over edges, soften sharp corners, and refine furniture profiles without switching between multiple tool sets. Whether you are working on solid hardwood cabinetry, MDF panels, or laminate surfaces, this set provides the precision and versatility needed for edge profiling work on handheld routers, router tables, and CNC routing machines.

Key Features

• 3 piece roundover bit set - covers three of the most commonly needed radii (1/4", 3/8", and 1/2") in a single purchase, reducing the need for multiple individual bits and keeping your workflow efficient.
• 1/4" shank diameter - compatible with a wide range of routers that accept 1/4" collets, including compact handheld routers and standard router tables, making this set broadly versatile for shop and jobsite use.
• Right-hand (RH) rotation - engineered for standard router operation, ensuring proper chip ejection and smooth cutting performance in the most common router configurations.
• 2-flute (2-tooth) carbide-tipped (HW) construction - hard tungsten carbide cutting edges maintain sharpness longer than high-speed steel alternatives, resulting in cleaner edge profiles and extended cutting life across solid wood, sheet goods, and composite materials.
• Ball-bearing guide pilots - follow the edge of the workpiece automatically, maintaining consistent depth of cut and reducing the risk of inconsistent profiles or tearout along the edge.

Why This Product

• Three radius options in one set - having 1/4", 3/8", and 1/2" roundover bits together means you can match the correct profile to the specific design requirement without purchasing bits one at a time, saving both cost and setup time.
• The 1/4" shank fits a broad range of handheld routers and router tables, making this set accessible to hobbyists and professionals alike without requiring a dedicated heavy-duty machine.
• Carbide-tipped (HW) cutting edges hold up to repeated use across demanding materials including hardwood, plywood, MDF, and laminates - reducing the frequency of sharpening or replacement.
• Right-hand rotation and ball-bearing pilots work together to guide the cut smoothly along the workpiece edge, producing repeatable, professional-quality roundover profiles on furniture edges, cabinet doors, and trim work.
