Why the Notched Style Insert Makes a Difference in Grooving

Have you ever tried cutting a groove and found the tool slipping or the cut becoming uneven? The notched edge on the NG3189R insert acts like a tiny gripping hook that bites just enough into the metal to control the cut without dragging or chipping. Think of it like the treads on your running shoes gripping the track – it keeps everything steady and smooth for a clean, consistent groove. This design helps the insert stay on course, giving you crisper profiles and less rework.

Setting It Up

  • Ensure your tool holder is compatible with the NG3189R insert style and size before installation.
  • Carefully align the insert notch with the holder’s seat for a secure fit.
  • Tighten the insert clamp firmly but avoid over-tightening to prevent cracking.
  • Check that the groove width and depth of cut settings match your project requirements.
  • Perform a test cut on scrap material to verify proper setup.

Keeping It Going
