Increased threading accuracy by 30% and reduced tool change downtime by 25%

Why the 10-Degree Positive Rake Angle Makes a Difference

The 10-degree positive rake is like the optimal tilt on a pizza cutter blade, letting it slice through dough smoothly instead of tearing it apart. Similarly, this rake angle allows the insert to cut through metal cleanly and with less resistance. This leads to less wear on the tool, smoother threads, and less effort on your machine—a practical benefit that keeps your project moving fast and yields top-notch results.

Installation and Maintenance Guide

Setting It Up

  • Ensure the threading holder matches the TPMC-43NV insert dimensions before installation.
  • Secure the insert properly through the thru-hole to prevent shifting during operation.
  • Check the positive rake angle orientation aligns with your threading direction.
  • Verify the external diameter compatibility (6-12 mm) for the workpiece before you begin.
  • Use proper torque settings to avoid damage or loosening during machining.

Keeping It Going

  • Regularly inspect the insert edges for wear or chipping.
  • Clean chips and debris from the insert and holder after each use.
  • Sharpen or replace the insert as soon as thread finish quality starts to decline.
  • Store inserts in a dry, organized workspace to prevent corrosion or loss.
  • Use recommended cutting fluids to reduce heat buildup and prolong tool life.

Buying Guide: Choosing the Right TPMC Inserts

  • Need help Selecting the right cut type? Standard cuts are ideal for general threading, while double cuts yield finer finishes.
  • Considering material compatibility? Match the insert's carbide grade with your workpiece metal for best results.
  • Pay attention to thread size requirements. Make sure the external diameter fits your specific threading job, between 6 and 12 mm for TPMC-43NV.
  • Look for rake angle preferences. Positive rake angles improve cut smoothness on internal threads.
  • Check your machine holder compatibility. Inserts must fit snugly to prevent wobble or poor thread quality.
  • Consider your volume of work. Longer-lasting inserts help reduce downtime and tool changes in high-output environments.
