Tungaloy TPMT110308-PS T9115 Insert

Premium T9115 CVD Grade | -PS Finishing Geometry | 0.8mm Radius

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

The Tungaloy TPMT110308-PS T9115 is a high-performance triangular turning insert designed for the high-speed finishing and semi-finishing of steel. Utilizing the legendary T9115 CVD coating, this insert is built for maximum wear resistance and thermal stability in continuous cutting. The -PS (Positive Sharp) chipbreaker provides a sharp cutting edge that minimizes cutting forces and ensures excellent chip control. With a reinforced 0.8mm corner radius, it balances surface quality with increased edge strength. 100% Made in Japan, it is the professional choice for high-productivity CNC machining.

T9115 CVD Technology

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

-PS Finishing Geometry

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

Enhanced 0.8mm Radius

The 0.8mm (ANSI 2) radius allows for higher feed rates while providing better edge toughness compared to 0.4mm versions.

⭐⭐⭐⭐⭐ "Original Packaging" - Rajesh G., India
"Beyond provided original Tungaloy inserts. Excellent performance on alloy steels. Professional B2B partner."

⭐⭐⭐⭐⭐ "Master of Speed" - Hiroshi T., Japan
"The T9115 grade handles the heat much better than other coated carbides. Smooth cutting and long life."

8. FAQ - Professional Support

Q: Is T9115 better than AH725 for steel?

A: For continuous high-speed turning of steel, T9115 (CVD) is superior due to its thermal resistance. AH725 (PVD) is better suited for interrupted cuts or stainless steel.

Q: Why choose the 0.8mm radius over 0.4mm?

A: The 0.8mm (08) radius offers higher edge strength and allows for faster feed rates while maintaining a stable surface finish.

Q: Can I use this for stainless steel?

A: T9115 is a dedicated P-class steel grade. For stainless steel, we recommend Tungaloy’s AH630 or AH645 grades.

Tech Tip: Optimizing Tool Life

The **T9115 CVD grade** is designed for high-temperature stability. By keeping your cutting speeds high (Vc > 250 m/min) and using the **-PS geometry**, you reduce the friction and heat transferred to the workpiece. **Tungaloy Japan** - Engineering your production success.

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.
