VP20RT Grade Advantage
The VP20RT Miracle PVD grade is optimized for high-toughness requirements. It excels in preventing thermal cracking and resisting built-up edge (BUE) during the machining of sticky materials like SUS304/316 stainless steel. Its stable performance makes it ideal for interrupted cuts.
GM Chipbreaker Geometry
The GM (General Machining) chipbreaker is an "all-round" performer. It is designed to handle a wide range of feed rates and depths of cut. Its geometry ensures stable chip breaking, preventing long chips from scratching the workpiece surface or tangling in the CNC spindle.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Stainless Steel (300/400) | 80 - 160 m/min | 0.05 - 0.18 mm/rev |
| Carbon & Alloy Steel | 100 - 190 m/min | 0.08 - 0.22 mm/rev |
