TaeguTec CCMT09T308FG TT8125
Precision PVD Coated Grade for Superior Stainless Steel Finishing Stability
Product Overview
"Which insert offers the best balance of edge strength and chip control for finishing 304/316 stainless steel at high stability?"
The TaeguTec CCMT09T308FG TT8125 is a versatile 80° rhombic turning insert specifically optimized for ISO M (Stainless Steel) and ISO P (Steel) finishing. Featuring the advanced TT8125 PVD-coated carbide grade, this tool utilizes a specialized sub-micron substrate that offers exceptional resistance to thermal cracking and adhesive wear. The FG chipbreaker (Finishing Geometry) is designed with a sharp rake angle to slice through "gummy" materials, while the 0.8mm corner radius provides the necessary edge strength for stable, high-quality surface finishes even in slightly interrupted cuts.
Key Features
A larger corner radius compared to the 04 series offers increased tool life and better edge security for demanding finishing tasks.
Advanced PVD coating provides a smooth surface that effectively prevents Built-Up Edge (BUE) in stainless steel machining.
Engineered for low cutting forces, ensuring dimensional accuracy and excellent surface integrity (Ra values).

Verified Global Feedback
"Strongest finishing edge"
The 0.8mm radius on the TT8125 grade is a game changer for our 316 shafts. Much tougher than the standard 0.4mm inserts.
— Marine Precision (USA)"Top Oberflächengüte"
The surface finish is consistently mirror-like. Predictable tool life across hundreds of parts in alloy steel.
— Feinmechanik GmbH (Germany)"Affidabile e Versatile"
A very solid finishing tool. The chipbreaker works exactly as described, even at very shallow depths of cut.
— Officina Meccanica (Italy)Frequently Asked Questions
1. When should I use 308 (0.8mm) instead of 304 (0.4mm)?
Choose the 308 (0.8mm) radius when you need higher edge security, higher feed rates, or if you are dealing with slightly interrupted cuts. The 304 is better for very tight corners or thin-walled parts.
2. Does this work on Titanium?
While TT8125 can handle some heat-resistant alloys, for dedicated Titanium machining, we recommend the TT8020 grade for superior thermal resistance.

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.
