TaeguTec SPMG050204DK TT6030
The Stainless Specialist: Engineered for Heat Resistance and Smooth Chip Control
Product Overview
"Struggling with work hardening or gummy chips in Stainless? The DK geometry and TT6030 grade are built to stay sharp."
The TaeguTec SPMG050204DK TT6030 is a high-performance 5mm indexable drilling insert specifically optimized for Stainless Steel (ISO M) and high-temperature alloys. While general-purpose inserts often fail due to built-up edge (BUE) in gummy materials, the TT6030 grade utilizes a specialized PVD coating with a smooth surface finish to prevent chip welding. The DK chipbreaker features a sharper edge profile than the standard DG, reducing cutting forces and heat generation—critical factors when drilling small-diameter holes in austenitic stainless steels like 304 and 316.
Core Advantages
A specialized PVD grade designed to maintain hardness at the high temperatures common in stainless steel drilling.
The DK chipbreaker reduces the "rubbing" effect, preventing work-hardening of the hole walls in tough materials.
Engineered specifically for the compact Size 05 pocket, ensuring perfect seating and stability during high-speed rotation.

Industrial Applications
- Precision drilling in medical instruments and aerospace fasteners.
- Machining of small-bore valves and fittings in 316L Stainless.
- Highly effective for applications requiring superior hole surface finish.
- Designed for setups with through-tool coolant for optimal chip flushing.
Why TT6030 for Stainless?
Optimized for M-group materials. Prevents built-up edge and notch wear. Use when tool life in 300-series stainless is the bottleneck.
The multi-purpose alternative. Use if your application involves heavy interruptions or unstable clamping.
Frequently Asked Questions
1. What is the difference between DG and DK chipbreakers?
DG is general-purpose. DK is sharper and specifically designed to slice through gummy materials like stainless steel, significantly reducing radial pressure on small drill bodies.
2. Can I use this for carbon steel?
Yes, but the TT6030 is overkill. For carbon steel, TT8020 or TT7400 will offer better cost-per-hole and wear resistance.
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.
