TaeguTec SPMG Indexable Drill Inserts | TT9030 PVD Grade
High-Performance DG Chipbreaker for Steel & Stainless Steel Drilling
Product Overview
The TaeguTec SPMG series is the global standard for indexable drilling performance. Engineered with the TT9030 PVD grade, these inserts feature a multi-layered coating that provides extreme heat resistance and edge toughness. The DG (General) chipbreaker is specifically designed to handle a wide range of materials—from carbon steel to difficult-to-machine stainless steels—ensuring that chips are broken into small, manageable segments to prevent tool failure and machine downtime.
Core Advantages of TT9030 & DG Geometry
- ✔ Advanced PVD Coating: The TT9030 grade is optimized for high-speed drilling where heat buildup is intense.
- ✔ Versatile DG Geometry: Exceptional chip control across P, M, and K material groups, reducing vibration.
- ✔ Precision S-Shape: Four cutting edges provide superior cost-per-hole economics compared to alternative shapes.

Q: Can I use SPMG inserts for steel and stainless with the same grade?
A: Yes! The TT9030 grade is specifically engineered to be a "universal" drilling grade for both Steel (P) and Stainless Steel (M).
Q: What coolant pressure is recommended?
A: For U-drilling, through-tool coolant with at least 15-20 bar is ideal to clear chips effectively from the hole cavity.
Q: Are these four-edged inserts?
A: Yes, the square SPMG shape provides 4 usable cutting corners, making it highly economical.
Industrial Tech Tip: When using the peripheral and central inserts, ensure the TT9030 grade is used on both to maintain balanced tool wear and prevent vibration. Always check for alignment accuracy before high-speed drilling.
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
