Taegutec SNMG Indexable Turning Inserts
High-Stability 8-Edge Solutions for Versatile Metal Cutting
Product Overview
"Which double-sided square insert offers the best economy and edge strength for heavy roughing of alloy steels and stainless components?"
The Taegutec SNMG series is a cornerstone of the TurnRush and RhinoRush families. As a double-sided 90° square insert, the SNMG provides a total of 8 cutting edges, making it one of the most cost-effective choices for CNC turning. Featuring Taegutec's proprietary GoldRush CVD and PVD coatings, these inserts are engineered to withstand high thermal loads and mechanical shock. The diverse range of chipbreakers—from the -FG for precision finishing to the -RT for heavy roughing—ensures optimal chip control across various depths of cut (Ap) and feed rates.
Key Performance Advantages
- Double-Sided Economy: 8 usable cutting edges significantly reduce the cost-per-component.
- High Edge Toughness: 90° square geometry provides maximum support behind the cutting edge for heavy-duty removals.
- Advanced Coating Technology: TT8115 and TT8125 grades utilize thick Al2O3 CVD coatings for extreme wear resistance in steel turning.
- Optimized Geometries: Specialized land designs reduce friction and heat build-up.

— Yukihiro T., JapanFrequently Asked Questions
Q: Why use SNMG over CNMG for roughing?
A: SNMG has a 90° corner angle compared to the 80° of CNMG. This provides a stronger edge and more carbide mass behind the tip, making it superior for heavy interrupted cuts and roughing.
Q: Which chipbreaker is best for chip control in mild steel?
A: The -PC or -MT chipbreakers are specifically designed to curl and break chips in low-carbon steels at medium feed rates.
Grade Selection Tip: For stainless steel milling/turning, always opt for the TT9030 PVD grade to prevent notch wear and thermal cracking.
