UJK Edge Breaking Router Bits

Perfect Edges Made Easy—No More Visible Tool Lines

A sharp, unfinished wood edge isn’t just uncomfortable to touch—it’s a weak point in your work. Sharp corners are prone to chipping and splintering. That’s why many woodworkers opt to “break the edge” by adding a subtle roundover or chamfer, improving both the durability and the feel of the finished piece.

The UJK Edge Breaking Router Cutter makes this step easy, delivering clean, controlled results every time. Unlike traditional roundover bits, this cutter is specially designed with edges that gradually recede from the radius—eliminating visible tool lines and leaving behind a smooth, seamless transition. Available in 1/4" shank with multiple radii (1mm to 6mm), it’s the perfect tool for precise edge removal resulting in a professional-grade finish.

Solving a Persistent Problem

One of the biggest frustrations with standard roundover bits is the visible tool line that appears when the router depth isn't dialed in perfectly—or if you apply uneven pressure while routing. That faint line along the edge might not seem like much, but it almost always needs sanding to remove, which takes extra time and compromises the precision of your radius. The UJK Edge Breaking Router Cutter is engineered to eliminate that issue entirely. Its cutting edges are uniquely shaped to gradually recede from the radius near the top and bearing, blending the cut into the surface without leaving a hard transition. The result? No visible lines, no extra sanding, and a consistently accurate, clean edge every time.

Made in Britain from hardened carbon steel with carbide cutting edges and a wear-resistant Xylan coating, these cutters provide long-lasting performance and consistent results.
