TaeguTec SCMT09T308-MT TT7015
Cast Iron Specialist: High-Velocity CVD Coating for Abrasive ISO K Materials
Product Overview
"Which positive square insert is best optimized for high-speed turning of cast iron components without suffering from rapid flank wear?"
The TaeguTec SCMT09T308-MT TT7015 is a dedicated solution for ISO K (Cast Iron) machining. The TT7015 grade features a thick, multi-layered CVD coating that provides an ultra-hard surface to resist the abrasion caused by sand inclusions and graphite flakes in grey and ductile iron. The MT (Medium) chipbreaker geometry is designed to balance cutting edge sharpness with thermal strength, effectively managing chips during medium turning passes. With a 0.8mm radius, this insert delivers excellent durability and surface finish, making it the industry standard for engine blocks, brake discs, and pump housings.
Key Features
Optimized for high-speed machining of grey and nodular cast iron with exceptional flank wear resistance.
A stable chipbreaker design that prevents vibration and ensures smooth material removal in intermittent cuts.
The 0.8mm nose radius provides a robust corner for high-feed applications and extended tool life.

Verified Global Feedback
"Excellent Life in Grey Iron"
We produce thousands of brake rotors monthly. TT7015 provides the most stable tool life we've found for these high-speed operations.
— Automotive Precision (USA)"Hervorragende Verschleißfestigkeit"
Outstanding resistance to abrasive wear in nodular iron. We were able to increase our cutting speeds by 20% over our previous supplier.
— Gießerei-Zerspanung GmbH (Germany)"Ottimo controllo del truciolo"
The MT chipbreaker handles ductile iron perfectly. No chip nesting, even in internal boring. Very satisfied.
— Meccanica Lombarda (Italy)"Reliable for Cast Iron"
Consistency is key for our automation. The TT7015 wear pattern is predictable, allowing us to plan tool changes accurately.
— Sato Heavy Industries (Japan)Frequently Asked Questions
1. Is TT7015 suitable for interrupted cuts in cast iron?
TT7015 is optimized for continuous and light interrupted cuts. For heavy interrupted cuts or extremely unstable setups, consider TT7025 for increased toughness.
2. Can I use this insert for steel (ISO P) materials?
The TT7015 grade is specifically formulated for cast iron. While it can cut steel, it may suffer from premature cracking due to lack of steel-specific coating properties. We recommend TT8125 for steel.

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.
