ISO Material Application Codes:
♦ = Supported operation type
Understanding ISO Material Codes
Higher numbers = Softer steels, interrupted cuts
Work hardens - PVD coatings preferred
Abrasive - Wear-resistant grades needed
- ✓ P15 (Finishing) - For harder steels with light cuts
- ✓ P20-P30 (General purpose) - Medium cuts on typical steels
- ✓ P35 (Roughing) - Heavy cuts on softer steels
Understanding MGMN Insert Types
The type letter in MGMN inserts (G vs M) indicates the insert profile and use case:
- • Groove only
- • Often sharper cutting edge
- • Designed for lighter cuts
- • Optimal for precision grooving
- • Medium-duty operations
- • Can handle more feed rate
- • Suitable for deeper cuts
- • More robust for tougher conditions
