Chris' Tips

Chris Chris' Tips
Make sure you get the correct inserts and retaining screws for your indexable turning tools.

Our chart of indexable inserts shows which inserts and which screw to use with each of our indexable tools.

What do TAR, TAL, TBR, TBL, TE mean?

These are designations for the turning tool holders (the black bars), not the inserts.

  • T indicates that it holds triangular inserts.
  • L & R indicate left and right hand tools. Right hand tools cut from right to left.
  • A indicates the insert has a zero degree side angle
  • B indicates the insert has a 15 degree side angle
  • E indicates the insert has a 30 degree side angle. In other words, the point is centered.
Now that you know that, so what? Use the tool that does the job at hand.
