TaeguTec CCMT060204FG TT8125
Advanced PVD Coated Carbide for High-Stability Stainless Steel Finishing
Product Overview
"Which insert is most reliable for achieving high-precision surface finishes on gummy stainless steels while preventing built-up edge?"
The TaeguTec CCMT060204FG TT8125 is a high-performance 80° rhombic turning insert engineered specifically for ISO M (Stainless Steel) and ISO P (Steel) finishing. Utilizing the cutting-edge TT8125 PVD coating, this grade features a tough sub-micron substrate and a smooth coating layer that effectively resists adhesive wear and thermal cracking. The FG chipbreaker (Finishing Geometry) is designed with a sharp rake angle to reduce cutting resistance, ensuring excellent chip evacuation and superior surface integrity during light-duty finishing passes.
Key Features
The FG geometry combined with PVD technology maintains a razor-sharp edge to slice through stainless steel without burr formation.
TT8125 is designed to prevent coating delamination, providing consistent tool life even in varying cutting conditions.
Excellent chip control at low feed rates (fn) prevents the long, stringy chips typically associated with 300-series stainless steels.

Verified Global Feedback
"Perfect for Medical Components"
Using the TT8125 on 316L. The surface finish is exceptional and the tool stays sharp much longer than my previous PVD grade.
— Precision Med-Tech (USA)"Hervorragend bei Edelstahl"
Very stable dimensions across 500-part batches. The FG chipbreaker is a lifesaver for long-chip control issues.
— Feinmechanik GmbH (Germany)"Molto Affidabile"
Great price-to-performance ratio. TaeguTec always delivers on quality for our lathe department.
— Meccanica S.R.L. (Italy)Frequently Asked Questions
1. What is the difference between TT8125 and TT9080?
TT8125 is a specialized grade specifically optimized for Stainless Steel finishing stability. TT9080 is a more versatile "multi-purpose" grade for Steel, Stainless, and Alloys.
2. Can I use this for boring small holes?
Yes, the 80° Rhombic CCMT 06 shape is ideal for internal boring. Ensure you use a compatible SCLCR 06 boring bar.

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.
