Freud Quadra-Cut Radius Rounding Over Bit with Perma-Shield Coating – 4 Cutters, 1/4" Shank, 3/8" Radius, 2-3/16" Length

Overview

The Freud Quadra-Cut Radius Rounding Over Bit is built for precise edge shaping across a range of woodworking tasks. Its Quadra-Cut design employs four cutting edges to deliver exceptionally clean, smooth finishes, even when crossing grain. With a 3/8 inch radius, a 2-3/16 inch overall length, and a 1/4 inch shank, this bit is versatile enough to fit many common routers while producing consistent results on doors, moldings, drawers, and decorative edges.

Maximize versatility with a smart upgrade option

For broader edge profiles without buying a new bit, you can swap in a bearing that’s 1/8 inch smaller in diameter to create a beading profile. This simple adjustment expands the range of finishes you can achieve, making the same bit more capable for a variety of design details on cabinetry and furniture.

Materials, compatibility, and workflow

This bit is designed to cut hardwood, softwood, plywood, and composites with steady, predictable results. It supports multiple router setups—CNC, handheld, and table-mounted—so you can incorporate it into your preferred workflow. Whether you’re shaping moldings, softening sharp edges on parts, or refining panel edges, this bit is intended to support you in achieving refined results.

Perma-Shield coating: durability and smoother cuts

• Perma-Shield coating reduces friction and bit drag for smoother operation.
• Resists resin buildup and corrosion to help extend tool life.

What you get and how it helps your projects

• Quadra-Cut design with four cutting edges for a clean finish on challenging stock.
• Edge rounding with a 3/8" radius that creates gentle, durable profiles.
• Four-cutters configuration, 2-3/16" in length, with a 1/4" shank for broad router compatibility.
• Router-agnostic flexibility—works with CNC, handheld, and table-mounted routers.

Care and best practices

Keep feeds steady and let the bit do the work. When switching bearings to create a bead profile, verify clearances and test on scrap material before final passes. Regularly clean residue after use to maintain cutting efficiency and coating performance.
