CMT 4-Piece Contractor Roundover Set by CMT is a carbide-tipped router bit collection designed for value-driven contractors, remodelers, and dedicated DIY woodworkers who need reliable edge profiling across a range of radii. This right-hand rotation set covers four of the most commonly used roundover sizes - 1/8 in., 1/4 in., 3/8 in., and 1/2 in. - all on a single 1/4 in. shank, giving you versatile edge-softening capability without swapping tool setups. Whether you are rounding over cabinet doors, furniture edges, trim details, or decorative molding, this set delivers consistent, clean profiles on solid hardwoods, softwoods, plywood, MDF, chipboard, laminates, melamine, and plastics.

Key Features

• 1/4 in. shank compatibility - fits a wide range of handheld routers and router tables, making this set accessible for most workshop and job-site setups without requiring a collet adapter.
• Four radius sizes (1/8 in., 1/4 in., 3/8 in., 1/2 in.) in one set - eliminates the need to purchase individual bits separately, covering light edge breaks through full half-inch roundovers for diverse trim and cabinetry profiles.
• Carbide-tipped (TCT) cutting edges - harder and more wear-resistant than high-speed steel, so the bits stay sharp longer when routing hardwoods, sheet goods, and composite materials.
• 2-flute (2-tooth) design - provides a balanced cut with good chip clearance, producing smoother finished surfaces on each pass and reducing the need for excessive sanding afterward.
• Right-hand (RH) rotation - matches the standard direction of virtually all handheld routers and router tables, ensuring safe, predictable cutting behavior right out of the box.
• Contractor-grade quality/price ratio - engineered to deliver professional results at an accessible price point, making this set practical for high-frequency remodeling work as well as occasional home improvement projects.

Why This Product

• Four of the most in-demand roundover radii are bundled together, so a contractor or remodeler can move from a subtle 1/8 in. edge break on trim to a bold 1/2 in. profile on furniture without stopping to source additional bits.
• The carbide-tipped construction means these bits maintain their cutting performance across demanding materials - hardwoods, plywood, MDF, laminates, and plastics - reducing downtime from dull tooling on busy job sites.
• The universal 1/4 in. shank makes this set compatible with handheld routers, router tables, and CNC routing machines, giving woodworkers and contractors flexibility to use the same bits across multiple machine setups.
• Designed specifically for value-conscious professionals and serious DIYers, this set offers a cost-effective path to a complete roundover toolkit without sacrificing the carbide quality needed for consistent, repeatable profiles.
