TaeguTec SPMG110408DG TT9030
Maximum Security Drilling: The Premier Grade for Interrupted Cuts and Shock Resistance
Product Overview
"Need a drilling insert that won't shatter when hitting a cross-hole? The TT9030 is your insurance policy for expensive workpieces."
The TaeguTec SPMG110408DG TT9030 is a mid-sized 11mm indexable drilling insert designed for the high-performance TOPDRILL and DrillRush lines. Engineered specifically for tough environments, the TT9030 grade features an ultra-tough sub-micron substrate paired with a PVD coating that excels at resisting mechanical shock and thermal cracking. The DG chipbreaker is the gold standard for versatility, providing excellent chip curling and breakage across ISO P (Steel) and ISO M (Stainless Steel), even when the setup lacks perfect rigidity or involves interrupted cutting paths.
Core Advantages
The TT9030 grade is specifically designed to absorb impact energy, preventing the edge chipping common in interrupted drilling.
Balanced cutting edge provides low cutting forces while ensuring chips are broken small enough for seamless evacuation.
The 0.8mm radius offers a robust edge profile that handles high-feed rates and resists the heat generated in deep-hole drilling.

The Reliability Standard
The SPMG110408DG TT9030 is the most trusted insert for machinists who prioritize process security. When drilling holes in 11.5mm pocket bodies, the stakes are high. TT9030 ensures that even if you encounter hardness variations in the material or vibration in the tool holder, the insert edge remains intact. It is the definitive "safety first" grade for modern CNC drilling.
"Drilled 500 holes in 316 Stainless with zero chipping. The TT9030 is impressive."

1. Is the DG chipbreaker suitable for aluminum?
While DG works, TaeguTec's specialized "AL" chipbreakers are better for non-ferrous materials. DG is optimized for Steel, Stainless, and Cast Iron.
2. What indicates that I should switch to the TT9030 grade?
If your current inserts (like TT8020) are chipping at the corner or breaking suddenly during the cut, you need the extra toughness of TT9030.
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.
