TaeguTec CCMT09T304FG TT8115
High-Wear Resistance PVD Grade for High-Speed Stainless Finishing
Product Overview
"Which insert is specifically designed to handle high cutting speeds in stainless steel while maintaining a mirror-like surface finish?"
The TaeguTec CCMT09T304FG TT8115 is a premium 80° rhombic turning insert engineered for ISO M (Stainless Steel) and ISO P (Steel) finishing. The TT8115 grade features a specialized PVD coating over a hard, wear-resistant substrate, making it ideal for applications requiring high surface speeds (Vc) and long tool life. The FG chipbreaker (Finishing Geometry) utilizes a sharp, positive rake angle that slices through gummy materials, effectively eliminating built-up edge and ensuring dimensional stability in high-volume production environments.
Key Features
The TT8115 grade is formulated for elevated cutting speeds, reducing cycle times without compromising the cutting edge.
Specifically tuned for light finishing depths, the FG chipbreaker provides excellent chip control and low cutting forces.
Ultra-smooth PVD surface prevents material welding, a common issue when machining stainless steel and low-carbon alloys.

Verified Global Feedback
"Productivity Jump"
We pushed our Vc up by 25% on 304 stainless with TT8115. The finish is mirror-like and the tool life is incredible.
— Precision Lathe Works (USA)"Top Oberflächengüte"
Consistent results on high-speed runs. The FG geometry handles chips perfectly at light depths of cut.
— CNC-Fertigung GmbH (Germany)"Molto Affidabile"
A very stable finishing insert for our stainless steel valve components. Zero issues with adhesion.
— Meccanica S.R.L. (Italy)Frequently Asked Questions
1. When should I choose TT8115 over TT8125?
Choose TT8115 for high-speed finishing where productivity is the priority. Use TT8125 for more stable, general-purpose stainless finishing at moderate speeds.
2. Can I use this for roughing?
No, the FG geometry is specifically designed for Finishing. For roughing, please see our "MT" or "RT" chipbreaker options in the same grade.

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.
