TaeguTec SCMT09T304-MT TT8020
The Versatile Specialist: High-Performance Square Insert for Stainless Steel & Alloys
Product Overview
"Which square insert offers the most reliable tool life and chip evacuation when turning 304 or 316 stainless steel under medium loads?"
The TaeguTec SCMT09T304-MT TT8020 is the go-to solution for ISO M (Stainless Steel) and ISO S (Super Alloys). The TT8020 grade is a sub-micron substrate combined with a high-toughness PVD coating, making it exceptionally resistant to notch wear and built-up edge (BUE). The MT (Medium) chipbreaker features a unique rake angle and groove geometry that forces chips to break even in gummy, ductile materials. This ensures your CNC machine runs continuously without the "bird-nesting" issues common in stainless steel turning.
Key Features
Optimized for medium-to-low cutting speeds with high feed rates, offering excellent resistance to thermal cracking.
Engineered for medium applications, providing excellent chip control across a wide range of feed rates in ISO M materials.
Reduces cutting forces and friction, ideal for thin-walled parts or long-reach boring operations.

| TT9080 | PVD | The Tough Choice: Optimized for heavy interrupted cuts and low speeds. |
Why Choose TaeguTec?
TaeguTec's legacy in metallurgical excellence makes the SCMT 09T304-MT TT8020 a top-tier choice for modern CNC shops. We understand that stainless steel is notoriously difficult to machine due to its work-hardening properties. By combining a highly resilient PVD coating with a precise MT chipbreaker, TaeguTec provides an insert that stays sharp longer and manages heat better than standard carbide. When your workflow involves high-cost materials like stainless steel or aerospace alloys, TaeguTec is the partner you need to ensure every part is within tolerance and delivered on time.
Verified Global Feedback
"Reliable Tool Life on 316SS"
We switched to TT8020 for our stainless valves. The chip breaking is excellent, and we see 30% more parts per edge than our previous brand.
— Precision Fluid Systems (USA)"Perfekt für Edelstahl"
Outstanding performance. No more bird-nesting on our CNC lathes. The MT chipbreaker is very well-designed for medium feeds.
— CNC Werkstatt Müller (Germany)"Grande Versatilità"
Using these for both stainless and some titanium jobs. Stable edge life and very good surface finish. Highly recommended.
— Meccanica di Precisione (Italy)"Consistent Quality"
The SCMT shape is perfect for our boring bars. The TT8020 grade is very consistent across batches. A dependable industrial insert.
— Sato Aerospace Components (Japan)Frequently Asked Questions
1. Is TT8020 suitable for interrupted cuts?
TT8020 has good toughness, but for heavy interrupted cuts in stainless steel, TT9080 is the preferred choice for maximum impact resistance.
2. Do I need to use coolant?
Yes. In Stainless Steel (ISO M), Full Wet Coolant is essential to reduce heat at the cutting edge and prevent work-hardening of the workpiece.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
