Stainless steels (e.g. 304/316) are ductile, work-harden easily and conduct heat poorly. The typical pain points are built-up edge (BUE), sticking and poor surface. Correct grade, groove and parameters are key.
For stainless, prefer YZ6030 / KT1505 substrate with MV deep groove — larger rake and better chip evacuation significantly reduce BUE. Used in 304/316 batch machining.
Higher speed, moderate feed, avoid too-small depth (prevents recurring cutting in the hardened layer); ample coolant (emulsion/mist). Too-small depth lets the tool idle in the hardened layer and wear fast.
Turning: rigid clamp-type holders (MWLNR/MCLNR); interrupted cuts use thicker inserts (e.g. DCMT11T308); milling uses sharp high-rake end mills. KEENCUTEER covers the full stainless workflow.
Titanium, heat-resistant alloys need dedicated substrate + coating and cooling, controlled feed and stable rpm. KEENCUTEER team assists optimization.
Which KEENCUTEER insert for stainless?
YZ6030 or KT1505 substrate with MV deep groove reduces BUE; used in 304/316 batch machining.
Why built-up edge on stainless?
High ductility, work-hardening and poor heat conduction cause chip welding to the edge. Larger rake/MV groove, higher speed and ample coolant help.
How to choose DCMT11T304 grade & groove?
By material: steel/low-alloy YZ6020+TM; stainless YZ6030/KT1505+MV; interrupted DCMT11T308+KT1505.
Tools for titanium / hard materials?
Dedicated substrate + coating and cooling, controlled feed and stable rpm; carbide drills/crown drills/U-drills; team assists.
