What was needed
Concave Radius Knurling Wheel, Convex Radius Knurling Wheel, Lathe Single Form Knurling Tool Holder
Requirements
  • Even pattern across a curved surface
  • Premium appearance
  • Grip on rounded parts
Result
A full, even knurl across the whole contour.

Problem

Torches, pens, fitness grips and many consumer products have rounded or contoured surfaces. A straight knurling wheel only touches the high point, so the pattern fades out at the edges.

Solution

Radius knurling wheels have a convex or concave rim that matches the part's curve, so the pattern is formed evenly across the whole contour.

  • Choose a concave wheel for convex surfaces (e.g. a rounded grip) and a convex wheel for concave surfaces.
  • Cut-type patterns give the sharpest decorative finish on aluminium and brass.

Benefits

Why it works

Even pattern on curves
