TaeguTec SPMG060204DG TT9030
Maximum Toughness: The Ultimate Solution for Interrupted Cuts & Unstable Drilling
Product Overview
"Struggling with insert chipping during interrupted cuts or unstable setups? The TT9030 grade is built for the toughest conditions."
The TaeguTec SPMG060204DG TT9030 is a high-toughness indexable drilling insert designed for the TOPDRILL series. While many inserts fail under impact, the TT9030 grade utilizes a specialized sub-micron substrate and a high-toughness PVD coating to absorb shock and prevent catastrophic failure. This makes it the premier choice for drilling through cross-holes, angled entries, or in setups with less than ideal rigidity. The DG chipbreaker provides a positive rake angle that reduces cutting forces, vital for the 06-size insert to maintain stability in Steel (ISO P) and Stainless Steel (ISO M).
Core Advantages
A dedicated "toughness-first" grade that prevents edge chipping in interrupted cuts and varying hardness materials.
Balanced chip control design ensures chips are broken small enough for fast evacuation in small diameter drill bodies.
The 0.4mm corner radius is perfectly suited for small diameter holes where high precision and low radial pressure are required.

Higher wear resistance. Best for continuous cuts and high-speed steel/stainless drilling.
The "Problem Solver" Grade
The SPMG060204DG TT9030 is often called the "safety grade." When your standard inserts are chipping or breaking due to machine vibration or part geometry, switching to TT9030 provides the reliability needed to keep the machine running. Its 0.4mm radius ensures low cutting pressure, making it a favorite for Swiss-type lathes and small VMCs.
"Solved our chipping issues in 304 Stainless cross-drilling. Very tough insert."

— Job Shop Owner (USA)Frequently Asked Questions
1. Should I use TT9030 if my setup is rigid?
If your setup is perfectly rigid and the cut is continuous, TT8020 will offer better tool life at higher speeds. Use TT9030 specifically when toughness is required over wear resistance.
2. Does this insert fit DrillRush bodies?
Yes, the SPMG 06 series is compatible with TaeguTec's indexable drilling systems that specify Size 06 pockets.
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.
