WCMX030208FN / WCMT040208 Carbide U-Drill Inserts for Stainless Steel Fast Drilling

This series of fast feed indexable U-drill inserts covers WCMX030208FN and WCMT040208 models, specially developed for high-efficiency hole machining on stainless steel. It fits standard U-drill tool bodies for CNC drilling, step drilling and chamfer drilling applications.

The optimized cutting edge profile and chip forming groove ensure smooth chip evacuation and reduce cutting heat buildup during deep hole drilling. Premium carbide substrate with specialized coating provides excellent wear resistance and edge toughness, resisting built-up edge on sticky stainless steel materials.

Produced to strict ISO dimensional tolerances, these inserts enable precise clamping and quick indexing on matched U-drill holders. Widely used in automotive, mold and general machinery manufacturing, they boost drilling productivity and lower tooling costs for stainless steel hole making.
