Tungaloy TPMT16T308-PS T9115 Insert

High-Speed CVD Coated Carbide | -PS Precision Finishing | 0.8mm Radius

What is the best insert for high-speed semi-finishing on steel?

The Tungaloy TPMT16T308-PS T9115 is a premium triangular turning insert optimized for high-productivity steel machining. Featuring the advanced T9115 CVD coating, this insert excels in high-speed finishing and semi-finishing applications by providing unparalleled crater wear resistance. The -PS (Positive Sharp) chipbreaker is specifically engineered to reduce cutting forces and ensure clean chip evacuation. With a robust 0.8mm corner radius, this model provides superior edge strength for stable production. 100% Made in Japan.

T9115 CVD Grade

Designed for high-speed turning of steel (ISO P15-P25). Thick Al2O3 and TiCN layers provide extreme heat resistance and surface hardness.

-PS Sharp Geometry

The 'Positive Sharp' breaker features a high rake angle, minimizing machine vibration and preventing work-hardening of the steel surface.

PremiumTec Treatment

Tungaloy's exclusive surface treatment reduces friction and improves chip flow, resulting in higher surface gloss and consistent performance.

8. FAQ - Support for Professionals

Q: Can I use T9115 for stainless steel?

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

Q: What is the benefit of the CVD coating?

A: CVD (Chemical Vapor Deposition) allows for a thicker, more heat-resistant coating compared to PVD, making T9115 ideal for continuous high-speed turning.

Q: Is 0.8mm radius better than 0.4mm for finish?

A: 0.8mm offers higher edge toughness and allows for higher feed rates, but 0.4mm is generally preferred for extremely light finishing passes where low cutting force is needed.

Tech Tip: Matching Grade to Speed

The **T9115 grade** is engineered to thrive in the high-temperature zone of CNC turning. When using the **-PS sharp edge**, maintaining high cutting speed prevents built-up edge and ensures a superior surface finish. **Tungaloy Japan** - Engineering your production advantage.

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.
