TaeguTec CNMG190608EM TT9225
The Versatile Heavyweight: Advanced CVD Grade for Stable Large-Scale Stainless Turning
Product Overview
"Which large-format insert offers the best balance of wear resistance and edge toughness when turning high-volume stainless steel components under varying stability?"
The TaeguTec CNMG190608EM TT9225 is a powerhouse 80° rhombic insert optimized for ISO M (Stainless Steel). The TT9225 CVD grade is engineered as a "universal" stainless solution, providing exceptional fracture toughness for light interrupted cuts and superior crater wear resistance for continuous passes. The EM (Medium-Duty) chipbreaker is designed to control gummy chips in materials like 304 and 316L, while the 19mm IC (Inscribed Circle) provides the structural mass needed for heavy material removal on large CNC lathes.
Key Features
A specialized coating-substrate bond that prevents delamination and edge chipping in difficult-to-cut stainless alloys.
Features a reinforced cutting edge that provides stable chip evacuation and prevents bird-nesting in automated production.
Extended 6.35mm thickness and 19.05mm IC offer maximum thermal mass to dissipate heat during heavy, long-duration cuts.

Verified Global Feedback
"Reliable for Big Shafts"
We use these for turning 304 shafts. The TT9225 grade is incredibly stable—even when we hit hard spots, the edge doesn't crumble.
— Heavy Industrial Machining (USA)"Top Performance on Stainless"
Excellent chip control on large depth of cuts. The 1906 size handles the torque much better than smaller inserts.
— Fertigungstechnik GmbH (Germany)"Predictable Tool Life"
Post-coating is very smooth. Mirror finish on 316L and very consistent tool life across shifts. Highly recommended.
— Precision Marine Parts (Italy)Frequently Asked Questions
1. Is the EM chipbreaker good for finishing?
The EM (Medium-Duty) breaker is optimized for medium depths of cut. For light finishing on large parts, ensure you maintain the minimum recommended feed rate to engage the breaker.
2. How does the 0.8 radius compare to 1.2 for heavy turning?
The 0.8mm radius offers slightly better vibration control on long-reach parts, whereas a 1.2mm radius would provide higher edge strength for aggressive roughing.

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.
