TaeguTec CCMT120408MT TT7015
Precision PVD Grade for High-Speed Stainless Steel & HRSA Turning
Product Overview
"Which insert grade offers the best edge toughness and thermal stability for medium turning of 304/316 stainless steel at high cutting speeds?"
The TaeguTec CCMT120408MT TT7015 is an 80° rhombic turning insert engineered specifically for ISO M (Stainless Steel) and ISO S (Super Alloys). Featuring the high-performance TT7015 PVD coating, this grade excels in managing the extreme heat generated during the machining of tough alloys. The MT chipbreaker (Medium Turning) is precision-ground to balance a sharp cutting action with enhanced edge strength, effectively preventing built-up edge (BUE). With its 0.8mm corner radius, this insert provides superior surface finish stability and increased resistance to edge chipping in continuous to slightly interrupted cuts.
Key Features
A TiAlN-based coating that maintains extreme hardness and oxidation resistance at high cutting temperatures.
Optimized for medium-duty finishing, ensuring reliable chip breaking in high-ductility materials like stainless steel.
Increased edge toughness for stable tool life and superior surface overlap in precision machining.

Global User Feedback
"Perfect for 316 Stainless"
Replaced our standard carbide with TT7015 on a high-speed stainless run. Tool life increased by 35% and the finish is excellent.
— Precision Lathe (USA)"Hervorragende Oberfläche"
Consistent results in Duplex stainless. The MT chipbreaker handles the gummy chips perfectly.
— Fertigungstechnik GmbH (Germany)"Ottimo per Inox"
Very stable performance in Titanium finishing. The 0.8mm radius provides a very robust edge.
— Officina Meccanica (Italy)Frequently Asked Questions
1. Can TT7015 be used on Carbon Steel?
While it can cut steel, it is optimized for Stainless and Super Alloys. For Carbon Steel, we recommend the TT8115 or TT8125 grades.
2. Is this insert suitable for dry machining?
When machining stainless steel, high-pressure coolant is highly recommended to manage heat and prevent built-up edge.

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.
