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 a versatile woodworking tool designed to deliver smooth, rounded edges on a variety of profiles. Built around Freud's exclusive Quadra-Cut geometry, this bit uses four cutting edges to help achieve a consistently clean surface, even when working with cross-grain materials. With its robust 1/4" shank and 3/8" radius, it’s ready for precision work on a range of projects from furniture to cabinetry.

Expandability through smart customization

A straightforward bearing swap lets you transform this rounding bit into a beading bit. By using a bearing that is 1/8" smaller in diameter, you can create a decorative bead edge and extend the utility of a single tool, reducing the need for additional bits for common edge profiles.

Materials and project versatility

• Hardwood, softwood, plywood, and composite materials can be shaped with precision for refined edges.
• Use this bit to mold edges on doors and drawers, soften sharp corners on trim, or add gentle rounding to molding details.

Router compatibility

• Suitable for CNC routers, handheld routers, and table-mounted routers, offering flexibility for different shop setups.
• Ideal for both DIY projects and professional woodworking workflows where repeatable edge quality matters.

Perma-Shield coating

The Perma-Shield coating reduces friction and resin buildup, helping the bit cut more smoothly and stay cleaner over long runs. It also provides corrosion resistance to help extend tool life in demanding environments.

Practical use and considerations

In practice, you might rely on this bit to soften sharp edges on interior doors, create rounded frames for cabinet doors, or add a finishing bead detail after profile work. When paired with a bearing for a beading profile, you can explore new edge treatments while maintaining consistent depth and alignment across parts. The result is a refined, tactile edge that enhances both appearance and structural feel without sacrificing precision.

Why choose Freud Quadra-Cut Radius Rounding Over Bit

This bit is designed for consistent results across various materials and router types. Quadra-Cut geometry helps minimize tear-out in cross-grain areas, while the lightweight, low-friction Perma-Shield coating supports smoother cuts and easier maintenance over time.
