TaeguTec DCMT070202FA TT9080
Mastering Stainless Steel: High-Toughness PVD Solution for Precision Finishing
Product Overview
"Which turning insert is best for finishing stainless steel parts while maintaining sharp edge integrity and preventing notch wear?"
The TaeguTec DCMT070202FA TT9080 is a high-precision turning solution specifically optimized for ISO M (Stainless Steel) and ISO S (High-Temperature Alloys). Featuring the ultra-tough TT9080 PVD Coated grade, this insert excels in environments where work-hardening and thermal shock are prevalent. The FA (Finishing-Automotive) chipbreaker is ground to a razor edge, providing exceptional chip control at very light depths of cut, ensuring a high-gloss surface finish and preventing vibration in slender workpieces.
Key Features
A specialized PVD coating over a sub-micron substrate that provides superior resistance to notch wear and edge chipping.
Peripheral ground geometry ensures a clean shearing action, reducing cutting temperature and work-hardening of the surface.
The FA chipbreaker is designed to break chips effectively at low feed rates, preventing "bird-nesting" on precision parts.

Verified Global Feedback
"Best for 316 Stainless"
We struggled with notch wear on our 316 valves. Switched to TT9080 and tool life increased by 40% with a much cleaner finish.
— Precision Fluidics (USA)"Perfekt für Medizintechnik"
The FA chipbreaker is incredibly sharp. Perfect for small medical screws where we need zero burrs on the stainless finish.
— Med-Tech GmbH (Germany)"Stable in Titanium"
Handles the heat of titanium turning very well. The 0.2mm radius stays sharp much longer than competing brands.
— Aero-Machining (Italy)Frequently Asked Questions
1. What makes TT9080 suitable for Stainless Steel?
TT9080 uses an ultra-fine substrate and a thin PVD coating that maintains a sharp edge while resisting the heat and work-hardening common in stainless alloys.
2. Can this insert be used for dry machining?
While TT9080 has high heat resistance, we highly recommend flood coolant when machining stainless steel to maximize surface finish and tool life.

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.
