TaeguTec SPMG090408DG TT9030
The Industrial Problem Solver: High-Toughness Drilling for High-Vibration Environments
Product Overview
"Struggling with insert breakage in cross-holes or angled exits? The 9mm TT9030 is engineered for maximum security."
The TaeguTec SPMG090408DG TT9030 is a specialized 9mm indexable drilling insert designed for the TOPDRILL and DrillRush product lines. Unlike brittle high-speed grades, the TT9030 grade features a robust sub-micron substrate and a multi-layered PVD coating optimized for toughness. This makes it the industry standard for interrupted cuts, drilling through welds, or working with unstable workpiece clamping. The DG chipbreaker provides a balanced cutting action that reduces radial pressure while ensuring chips are fragmented for rapid evacuation in Steel (ISO P) and Stainless Steel (ISO M).
Core Advantages
Specifically formulated to prevent catastrophic edge failure during heavy impacts and mechanical shock.
The DG geometry creates a curved chip profile that prevents "bird-nesting" even in gummy materials like 304 stainless.
The 0.8mm corner radius provides a reinforced cutting edge, distributing heat and pressure to extend tool life.

Standard grade with higher wear resistance for stable, continuous drilling.
The Reliability Leader
The SPMG090408DG TT9030 isn't just an insert; it's insurance for your expensive workpieces. For 9mm drilling operations where the path is interrupted or the machine lacks rigidity, this grade absorbs the energy that would shatter other carbides. By choosing the TT9030, you prioritize process reliability and minimize catastrophic tool failures.

1. What is the difference between the DG and TG chipbreakers?
The DG is the general-purpose geometry for broad applications. The TG is typically used for higher feed rates or specifically tough steel materials, but the DG is the most versatile for most shops.
2. Does this fit standard SPMG toolholders?
Yes, it fits any toolholder designed for ISO SPMG 09 inserts. It is perfectly optimized for TaeguTec's TOPDRILL bodies.
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.
