CMT Round Nose Bit - W/Out Bearing - 1/4 in. Radius - 1/4 in. Shank

CMT Round Nose Bit - Without Bearing - 1/8 in. Radius - 1/4 in. Shank

Create distinctive grooves, engravings, and decorative details with precision and control.

CMT Round Nose Router Bits are designed for creating smooth, rounded grooves and decorative engravings in wood and wood-based materials. This bit features a 1/8 in. radius cutting profile and a 1/4 in. shank, making it an excellent choice for detailed woodworking, sign making, cabinetry, furniture accents, and craft projects.

The rounded cutting profile produces clean, consistent grooves that can be used to personalize doors, drawer fronts, cabinet panels, signs, plaques, and other flat surfaces. The bit's compact 1/8 in. radius is well suited for fine decorative work where a smaller, more refined groove is desired.

Manufactured by CMT, these round nose bits are available in solid carbide or carbide-tipped configurations, providing reliable cutting performance and durability for demanding woodworking applications. The 1/4 in. shank is compatible with routers equipped to accept 1/4 in. collets.

This without-bearing design is intended for guided or freehand routing applications where a bearing is not required. When used with a router table or appropriate guide system, it provides excellent control for producing repeatable decorative patterns and grooves. For more elaborate designs, CMT also offers bearing-guided versions that can be used with templates.

Round nose bits are a favorite among professional sign makers, cabinetmakers, furniture builders, craft makers, and woodworking hobbyists. Use them to add decorative accents, engraved details, fluted effects, lettering backgrounds, and custom motifs to your woodworking projects.

Shop Tips:

For the best results when creating deeper grooves or decorative profiles, make multiple shallow passes rather than removing all the material in one cut. Begin with a light initial pass and gradually increase the cutting depth. This approach helps improve control, reduce stress on the router bit, and minimize the possibility of splintering or tear-out.

Always secure the workpiece firmly and use the appropriate router speed, feed rate, and cutting depth for the material being machined. Make sure the bit is fully seated and securely tightened in the router collet before operation.
