Tungaloy TPMT110304-PS T9115 Insert

Premium T9115 CVD Grade | -PS Finishing Geometry | Made in Japan

What is the best Tungaloy grade for high-speed steel turning?

The Tungaloy TPMT110304-PS T9115 is a high-performance triangular turning insert designed for the high-speed finishing and semi-finishing of steel. Featuring the legendary T9115 CVD coating, this insert is built for maximum wear resistance and thermal stability. The -PS (Positive Sharp) chipbreaker provides a sharp cutting edge that minimizes cutting forces and ensures excellent chip control at light depths of cut. 100% Made in Japan, it is the professional industrial choice for high-productivity CNC machining environments.

T9115 Premium Grade

A thick Al2O3 and TiCN CVD coating that offers extreme hardness and resistance to crater wear, optimized for ISO P15-P25 steel turning.

-PS Sharp Geometry

Designed with a positive rake angle for light finishing. It drastically reduces machine load and prevents surface marring by clearing chips effectively.

Heat & Wear Resistance

The PremiumTec surface technology reduces friction and provides a smooth surface, leading to longer tool life and higher dimensional accuracy.

8. FAQ - Professional Support

Q: Is T9115 suitable for interrupted cuts?

A: T9115 is a high-speed finishing grade with extreme hardness. For heavy interrupted cuts, we recommend the tougher AH725 grade.

Q: Why use the -PS chipbreaker?

A: The -PS geometry is optimized for finishing. It reduces machine load and provides a sharper cut, ensuring superior surface Ra values.

Q: Can I use this on stainless steel?

A: T9115 is a dedicated steel grade (P-class). For stainless steel (M-class), we suggest the AH630 or AH645 grades for better results.

Tech Tip: Optimizing High-Speed Turning

The **T9115 CVD grade** is designed for the high-temperature zone. By combining this grade with the **-PS sharp geometry**, you can run your CNC at higher RPMs without sacrificing tool life. **Tungaloy Japan** - Leading the world in turning efficiency.

Technical FAQ & Buying Guide

How do I choose the correct specification?

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.

How can I check compatibility with my existing setup?

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.

What quantity and price unit am I 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.

How should I choose cutting parameters?

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.

Are bulk discounts available?

Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.
