Sr1 Replacement Cutter for Pen and Mini Carbide Turning Tools, Square Radius

Replacement Square Radius Cutter for our corresponding Mini and Pen Turning Ergonomic Carbide Turning Tools.
Item #

Take a close look at the edge of this carbide insert and you'll realize it's not actually square. Instead, each of its four edges is slightly crowned with a 2'' radius. This subtle change makes the cutter excellent for smoothing cuts. Use it with the corresponding Rockler Mini Ergonomic Carbide Turning Tool (#49804, sold separately) or with the square radius tool included in our 3-Piece Pen Turning Set (#47600, sold separately). No sharpening required — just rotate to a new edge when the previous edge gets dull, and replace the cutter when needed.


  • Crowned edges for smooth finishing cuts
  • Solid carbide for a long life
  • Factory sharpened—ready for use right out of the box
