Tungaloy TPMT16T304-PS T9115 Insert

High-Speed CVD Coated Carbide | -PS Precision Finishing | Made in Japan

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

The Tungaloy TPMT16T304-PS T9115 is an industrial-grade 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 at light depths of cut. 100% Made in Japan, it is the professional choice for CNC operators requiring high dimensional stability and long tool life.

T9115 CVD Coating

Utilizes thick Al2O3 and TiCN layers for extreme heat resistance and surface hardness. Optimized for ISO P15-P25 steel applications.

-PS Sharp Geometry

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

PremiumTec Technology

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

Industrial Cutting Parameters (Steel Finishing)

  • Cutting Speed (Vc): 150 - 450 m/min (Recommended: 280 m/min)
  • Feed per Rev (f): 0.05 - 0.20 mm/rev
  • Depth of Cut (ap): 0.2 - 2.0 mm

*Note: T9115 is a high-speed grade. To prevent edge build-up, ensure cutting speeds remain above 250 m/min.*

4. Primary Applications

  • High-speed turning of Carbon Steel, Alloy Steel, and Bearing Steels.
  • Shaft, flange, and precision valve manufacturing.
  • Mass production finishing requiring stable tool life.
  • Excellent for CNC lathes with high spindle speeds.

5. Tool Compatibility

Compatible with all standard ISO TPMT 16T3 tool holder pockets. Optimized for STFCR/L internal boring bars and STGCR/L external turning tools. Fits Mazak, Haas, Citizen, and Okuma CNC machines.

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 better 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 -PS breaker suitable for heavy roughing?

A: No, -PS is a sharp finisher breaker. For heavy roughing, please consider the -TM or -TH chipbreakers from Tungaloy.

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 a 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.
