Frequently Asked Questions

What is a roundnose (core-box) bit used for?

It cuts a smooth half-round groove for coves, decorative veins, fluting, and rounding the interior edges of bowls and trays. Browse related router bit sets.

What radii are in this set?

The three bits offer 1/8", 1/4", and 3/8" radii for fine to bold cove cuts.

What shank size do these bits use?

All three bits have 1/4" shanks, so they fit compact and full-size routers with a 1/4" collet.

How does this differ from the 1/2" shank roundnose set?

This set has 1/4" shanks with cutter heights of 1/4" to 7/16", suited to lighter routers and finer detail work, whereas the 1/2" shank version offers taller cuts. See more carbide router bits.

What projects can I make with these bits?

Fluted legs and columns, sign lettering, decorative panels, serving trays, and bowl interiors are all good uses. Explore our specialty router bits for more decorative options.

What is the largest cutting diameter?

The 14-190 has a 3/4" large diameter and a 3/8" radius, the boldest profile in the set.

Are these carbide-tipped bits?

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

Can I use these in a router table?

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

Will these fit a 1/2" collet router?

These have 1/4" shanks, so a 1/2" collet router would need a 1/4" reducer sleeve to run them.

Who makes this roundnose bit set?

It is made by Infinity Cutting Tools under the Infinity Tools brand.
