CMT Round Nose Bit – 1/4 in. Shank Carbide Router Bit

Create Custom Engravings, Decorative Grooves and Signature Designs

Personalize cabinet doors, drawer fronts, panels, cutting boards, signs and virtually any compatible wood surface with the CMT Round Nose Bit. Designed for creating smooth, rounded-bottom grooves and engraved details, this router bit is an excellent choice for woodworking projects that require decorative accents or custom motifs.

CMT round nose bits are available in solid carbide and carbide-tipped configurations, providing a wide selection of diameters and cutting depths to help you achieve the desired look. The rounded cutting profile produces clean, consistent grooves in wood and wood-based materials, making these bits especially useful for decorative engraving, fluted designs, lettering and artistic details.

When mounted in a router table, the bit can be used for working materials up to approximately 1.24 in. thick, depending on the specific bit configuration and setup. These bits are also well suited for creating the rounded groove sometimes used as a “juice groove” on charcuterie and cutting boards.

Versatile Applications

• Create decorative grooves and rounded-bottom channels in wood.
• Engrave custom designs, patterns and motifs.
• Add decorative details to cabinet doors and drawer fronts.
• Create grooves for cutting boards and charcuterie boards.
• Produce custom signs and personalized woodworking projects.
• Ideal for professional sign makers, craft makers and woodworking hobbyists.
• Use with templates when paired with compatible top-bearing configurations for additional decorative possibilities.

Designed for Creative Woodworking

The CMT Round Nose Bit gives woodworkers the flexibility to add unique details to both functional and decorative projects. Select the appropriate cutter diameter and cutting depth for the desired groove or engraving effect, then make controlled passes to create smooth, consistent results.

For more elaborate designs, CMT also offers top-bearing round nose configurations that can be used with templates. This makes it possible to reproduce intricate patterns and create distinctive designs on doors, drawer fronts, panels and other woodworking projects.

Shop Tips

For the best results, multiple passes are recommended when creating deeper grooves or working along an edge. Begin with a shallow initial pass and gradually increase the cutting depth. Taking lighter passes helps reduce the potential for splintering and gives you greater control over the finished profile.

Always secure the workpiece properly, use the appropriate router speed for the bit and material, and feed the workpiece steadily for clean, controlled cuts.
