TaeguTec SPMG110408DK TT6030
Advanced Stainless Solutions: Engineered for Reduced Friction and Superior Heat Dissipation
Product Overview
"Tackle the most demanding Stainless Steel (ISO M) applications with the precision of the 11mm DK geometry."
The TaeguTec SPMG110408DK TT6030 is a high-performance 11mm indexable drilling insert designed for the TOPDRILL and DrillRush platforms. This insert is a dedicated solution for machining Stainless Steel and High-Temperature Alloys. The TT6030 grade features a specialized PVD coating with an ultra-smooth surface finish that minimizes chemical affinity, effectively preventing built-up edge (BUE). The DK chipbreaker provides a sharper, more positive cutting edge compared to standard geometries, reducing radial forces and heat generation—essential for maintaining hole quality in work-hardening materials like 316L stainless steel.
Core Advantages
Optimized to resist thermal shock and oxidation, allowing the insert to thrive in the high-heat environments typical of stainless drilling.
The sharp DK geometry slices through gummy materials, preventing the "smearing" that leads to premature tool failure.
Specifically balanced for 11mm pockets, providing the structural rigidity needed for mid-sized hole production in tough alloys.

Performance Comparison
Optimized for M-Group materials. Features the sharpest DK edge and anti-adhesive coating to eliminate chip welding.
Best suited for heavy interrupted cuts or vibrating setups across multiple ISO groups.
Frequently Asked Questions
1. Why is the DK chipbreaker preferred over the DG for stainless?
The DK geometry has a higher positive rake. In "gummy" materials like stainless, this allows the insert to cut the chip cleanly, preventing the material from sticking to the rake face and causing edge breakdown.
2. Is through-tool coolant mandatory with the TT6030 grade?
While not technically mandatory, it is highly recommended. Stainless steel has poor heat conductivity; through-tool coolant ensures the TT6030's thermal properties are utilized to their fullest for maximum tool life.
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.
