Turning Inserts

Breakdown of ISO Reference

Higher Number = Tougher / Resistant to Impact
Lower Number = Harder / Wear Resistant

TU5525 the New Universal Turning Grade

TU5525 is a truly universal tuning grade suitable for cutting Steel, Stainless Steel, Cast Iron and heat resistant Aaloys. There is no need to hold stock of a multitude of grades reducing the cost of inventory and time wasted changing inserts. One insert for almost all applications.

TP2135 a Tough Impact Resistant Grade

If insert breakage or chipping of the cutting edge is a problem TP2135 may be the answer. Some application do not offer the cutting edge a constant cutting surface whether from a non round part or holes in the part this constant impact on the cutting edge can lead to insert failing. TP2135 is designed to take higher impact loads giving a more secure cutting edge, suitable for cutting steel, stainless steel and heat resistant alloys.
