CMT Roundover Bit - 3/16 in. Radius - 1/4 in. Shank

CMT Round Over Bit – 3/16 in. Radius – 1/4 in. Shank

A Roundover Bit is one of the most versatile profiles you can add to your woodworking toolkit. Whether you’ re simply softening sharp edges or creating more detailed projects like drop leaf tables, this bit delivers smooth, professional results. For even more design possibilities, pair it with our Cove Bits featuring the same radius.

Safety Tips: Always wear a dust mask and eye protection when operating a router.

Safety Precautions: Never use damaged or worn router bits. Always follow the recommended feed rate and avoid forcing the bit through the material. Take extra care when making the first cut with smaller diameter bits. For the best performance and finish, make deeper cuts in multiple passes rather than removing too much material at once.

How CMT Produces High-Quality Router Bits

• Precision Turning, Milling, and Cutting: CMT continues to invest in advanced manufacturing technology to ensure exceptional quality and consistency. Fully automated CNC machinery, operated by specially trained technicians, produces router bit shanks and bodies with precise dimensions and perfect balance.
• Heat-Forged Steel Bodies for Large Diameter Bits: Larger diameter router bits require additional manufacturing steps to achieve maximum strength and durability. By heat forging the steel before machining it into precise bit bodies, CMT creates a radial grain structure that enhances the strength and performance of these demanding tools.
• Advanced Brazing Technology: CMT has perfected the brazing process with custom-designed computerized equipment that provides a more consistent bond than traditional hand brazing. The silver-copper-silver brazing sandwich creates a strong connection between the steel body and carbide tips while adding shock absorption to help protect the carbide during demanding cuts.
• Specially Formulated Carbide for Every Application: Different woodworking projects require different levels of performance, which is why CMT develops carbide formulations tailored to specific cutting needs. From ultra-hard carbide for challenging materials like laminates to more impact-resistant formulas for large profiles, each tool is designed for the job at hand.
• Precision Grinding and Sharpening: Every CMT router bit receives a final sharpening process using multi-axis CNC grinding machines. Each cutting edge is finished with micron-level precision to provide the ideal balance of sharpness, durability, and long-lasting performance.
