Taegutec SOMT Indexable Inserts
High-Efficiency 4-Edge Geometry for Milling and Rapid Drilling
Product Overview
"Which square indexable insert provides the highest metal removal rate (MRR) while maintaining edge toughness during high-feed milling in hardened steel?"
The Taegutec SOMT series is a versatile, high-performance solution designed for both high-feed milling and indexable drilling applications. Featuring a robust square geometry with four cutting edges, the SOMT insert is engineered to handle heavy chip loads and high axial forces. With specialized PVD coatings (TT9030/TT8020), these inserts offer exceptional resistance to thermal cracking and notch wear. The unique chipbreaker design ensures optimal chip formation, making it a reliable choice for deep cavity milling and high-speed hole making where process security is paramount.
Key Performance Advantages
- Dual-Purpose Design: Optimized for use in both high-feed milling cutters and U-drill bodies.
- Advanced PVD Grades: TT9030 (Nano-AlTiN) provides the heat resistance needed for high SFM operations.
- High Edge Strength: Reinforced cutting edge prevents micro-chipping during interrupted cuts.
- Four Cutting Edges: Significant reduction in cost-per-edge compared to traditional triangular or round inserts.

— Hiroshi S., JapanFrequently Asked Questions
Q: Can SOMT inserts be used for finishing?
A: SOMT is primarily designed for high-feed roughing. For high-precision finishing, a ground-class insert like SPGG or specific finishing geometries would be more appropriate.
Q: What feed rates are recommended for SOMT in U-drills?
A: In drilling applications, feed rates (fn) typically range from 0.08mm to 0.20mm per revolution depending on the diameter and material hardness.
