The Freud PC132 3-3/4" (Dia.) Performance System® Combination Convex & Concave Radius Cutter is crafted for woodworkers who chase precise curves and versatile edge profiles. This cutter head is specially designed to cut either a radius concave or a radius convex profile, giving you the flexibility to craft decorative and structural radii with a single toolhead.

• Diameter: 3-3/4" (Dia.) for stable, consistent radii across a range of projects
• Profile capability: Combination convex and concave radius profiles—switch between shapes by changing profile knives
• Balance: Computer balanced to minimize vibration and deliver smoother, cleaner cuts
• System: Part of the Freud Performance System®, designed to work within that ecosystem for dependable, repeatable results
• Knife requirement: Requires two profile knives to complete the cut (knives sold separately)

Ideal for cabinetry, furniture, and architectural details, the PC132 makes it easier to add rounded edges, arcs, and curved profiles without juggling multiple tools. Use it to create curved cabinet doors, decorative edge treatments on panels, arches, moldings, or any project that benefits from precise radius contours. The ability to produce both convex and concave shapes with one cutter head helps you finish more work in less time, while preserving grain continuity for a seamless look.

How it works is straightforward: install two profile knives (sold separately) into the PC132, attach to your router within the Freud Performance System framework, and dial in the desired radius. Run test cuts on scrap wood to fine-tune depth and feed rate, then apply the same setup to your actual piece for consistent results. The computer-balanced design minimizes chatter, so you get crisp radii with fewer passes and less sanding.

Who should consider the PC132? Professional cabinetmakers, furniture builders, and serious hobbyists who frequently design curved edges or want to expand their repertoire with uniform convex/concave curves. If you’re upgrading a router toolkit for more complex profiles, this cutter head delivers proven precision, repeatability, and the flexibility to switch between radii as your project demands—without switching tools.

Practical tips for best results:

• Plan your radii around two knives—have both knives ready and correctly oriented for quick swaps.
• Always test on scrap material to dial in depth, feed rate, and noise levels before working on the final piece.
• Keep knives sharp and clean to preserve edge quality and avoid tear-out, especially on tough hardwoods.
• Follow your router’s and Freud’s Performance System guidelines for safe mounting and operation.
