CMT Roundover Bit - 3/8 in. Radius - 1/4 in. Shank

CMT Round Over Bit – 3/8 in. Radius – 1/4 in. Shank

The CMT Round Over Bit is one of the most versatile router bits in any woodworking shop. Perfect for softening sharp edges, creating comfortable finished corners, and adding decorative details, this bit is ideal for both everyday projects and more advanced applications like drop-leaf tables when paired with CMT Cove Bits of the same radius.

Designed for smooth, consistent results, CMT router bits are built with precision manufacturing, durable materials, and carefully engineered cutting edges to deliver excellent performance across a wide range of woodworking tasks.

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

Safety Precautions: Never use damaged or worn bits. Always operate at the recommended feed rate and avoid forcing the bit through the material. Take extra care when making the initial cut with small-diameter bits. For the best results, make deeper cuts in multiple passes.

How CMT Produces High-Quality Router Bits

• Precision Turning, Milling, and Cutting: CMT uses advanced automated CNC machinery operated by specially trained technicians to ensure router bit bodies and shanks are accurately machined, perfectly balanced, and built for reliable performance.
• Heat-Forged Steel Bodies for Large Diameter Bits: Larger diameter bits may require additional manufacturing steps, including heat forging the steel before precision machining. This process creates a stronger radial grain structure for improved durability and stability.
• Advanced Brazing Technology: CMT’s custom-designed computerized brazing process creates a secure bond between the steel body and carbide cutting edges. The silver-copper-silver brazing system helps absorb shock and protect carbide tips during demanding cuts.
• Application-Specific Carbide Formulations: CMT develops carbide blends designed for specific woodworking applications. From ultra-hard carbide for demanding materials like laminates to impact-resistant formulations for larger profiles, each bit is engineered for the job.
• Precision Grinding and Sharpening: Every cutting edge is finished on multi-axis CNC grinding machines for exceptional accuracy. Each bevel and angle is precisely sharpened to create a razor-sharp edge with long-lasting durability.
