Create Custom Engravings, Decorative Grooves and Signature Designs

The CMT Round-Nose Router Bit is designed for creating smooth, rounded-bottom grooves and decorative engravings in wood and wood-based materials. With a 1/4 in. diameter cutting profile, 5/8 in. cutter height, and 1/2 in. shank, this router bit is an excellent choice for adding distinctive details to doors, drawer fronts, panels, signs, cutting boards and other woodworking projects.

Constructed for precision routing, CMT round-nose bits are available in solid carbide or carbide-tipped configurations to deliver clean, consistent results. The rounded cutting profile is particularly useful for decorative engraving, sign making, veining and creating grooves with a smooth, finished appearance. When mounted in a router table, the bit can be used on materials up to approximately 1.24 in. deep.

This versatile bit is also well suited for cutting the decorative "juice groove" commonly found on charcuterie and cutting boards. Whether you're producing custom cabinetry, personalized signs, craft projects or detailed woodworking pieces, the CMT Round-Nose Router Bit gives you the flexibility to create distinctive designs.

Ideal for Custom Woodworking

Use the CMT Round-Nose Router Bit to personalize doors, drawer fronts, panels and other wood surfaces with your own signature motif. It is a popular choice among professional sign makers, furniture builders, craft makers and woodworking hobbyists.

For more elaborate decorative patterns, pair your router with a suitable template and bearing-guided bit to reproduce intricate designs consistently across multiple workpieces.

Shop Tips

• Make multiple passes: When creating deeper grooves or decorative profiles, take several lighter passes rather than removing all the material at once.
• Start shallow: Begin with a shallow initial pass and gradually increase the cutting depth to help minimize splintering and produce a cleaner finish.
• Use a router table: A router table can provide increased stability and control when working with larger panels or creating consistent decorative grooves.
• Secure your workpiece: Always make sure the material is firmly supported and secured before routing.
