Frequently Asked Questions

What is a roundnose or core-box bit?

A roundnose bit cuts a smooth half-round groove. It's used for coves, decorative veins, fluting, and rounding the interior edges of bowls and trays. See related router bit sets.

What radii are in the 3-piece set?

The set includes 1/8", 1/4", and 3/8" radius bits, scaling from a fine detail cove to a bold channel.

What shank size do these bits use?

All three bits have 1/2" shanks, so your router must accept a 1/2" collet.

What projects suit roundnose bits?

Use them for fluted columns and legs, signs and lettering, decorative panels, serving trays, and the inside edges of bowls. For more decorative cutters, see our specialty router bits.

Can these bits round out bowls and trays?

Yes. The product information notes you can use them to round out the interior edges of bowls and trays for a smooth, finished look.

What is the cutting height of the largest bit?

The 14-627 (1/4" radius) and 14-690 (3/8" radius) both have a 1-1/4" carbide height, the tallest in the set.

Are these carbide-tipped bits?

Yes. Each is a carbide-tipped roundnose bit built for clean cuts and long edge life. Maintain them with sharpening supplies.

Can I use these in a router table?

Yes. Roundnose bits work handheld for fluting or mounted in a router table for controlled decorative grooves.

Is there a top-bearing version for door fronts?

The product information mentions top-bearing roundnose bits for unique doors and drawer fronts; browse our broader carbide router bits for those options.
