Tungaloy TCMT110204-PS T9115 Turning Insert

High-Performance CVD Coated Carbide | T9115 Steel Grade | 0.4mm Precision Radius

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

The Tungaloy TCMT110204-PS T9115 is a premium triangular indexable turning insert engineered for high-precision finishing operations on ISO P (Steel) materials. Featuring the advanced T9115 CVD coating, this insert provides exceptional wear resistance and thermal stability during high-speed machining. The 0.4mm corner radius (04) and the -PS (Power Sharp) chipbreaker are optimized for light depths of cut, ensuring superior chip evacuation and a high-gloss surface finish. 100% Made in Japan, it is the ideal solution for CNC shops prioritizing dimensional accuracy and reduced downtime.

T9115 CVD Grade

A specialized CVD coated grade with a thick Alumina (Al2O3) layer. It offers extreme crater wear resistance at high temperatures, allowing for cutting speeds far exceeding standard carbide.

-PS Sharp Breaker

The "Power Sharp" geometry features a highly positive rake. It minimizes cutting force and prevents built-up edge (BUE), which is crucial for finishing low-carbon steels.

0.4mm Radius Precision

The 0.4mm corner radius (04) offers the perfect balance between edge strength and surface smoothness, allowing for precise corner details while maintaining tool durability.

Real Feedback from Global Machinists

⭐⭐⭐⭐⭐ "Consistent Finishing" - James D., USA
"The 0.4 radius is my go-to for finishing steel pins. T9115 grade holds the tolerance perfectly throughout the batch."

⭐⭐⭐⭐⭐ "Top Grade" - Karl R., Germany
"Excellent wear resistance. We use these in our high-speed boring bars and the surface finish is mirror-like."

⭐⭐⭐⭐ "Very Stable" - Lin S., Singapore
"Consistent chip breaking and predictable tool life. Genuine Tungaloy product with fast shipping."

⭐⭐⭐⭐⭐ "Industrial Reliable" - Marco V., Italy
"The -PS breaker handles light cuts beautifully. No stringy chips and the Ra is better than advertised."

⭐⭐⭐⭐⭐ "Five Stars" - Arjun P., India
"Beyond OYYU is a reliable supplier. These T9115 inserts significantly reduced our tool cost per part."

8. FAQ - Professional Support

Q: Is T9115 better than T9215 for finishing?

A: T9115 is a classic, highly stable grade. While T9215 is newer, many shops prefer T9115 for its predictable performance in precise finishing passes.

Q: Does this fit my existing S12M-STFCR11 boring bar?

A: Yes, it is fully compatible with any STFCR/L or STUCR/L holder using TCMT 1102 size inserts.

Industrial Tip: CVD vs. PVD for Steel

Select **T9115 CVD Carbide** when your priority is tool life during long, continuous high-speed finishing runs. The thermal protection of Alumina coating allows for higher productivity without losing edge integrity. For precision steel turning, **Tungaloy Japan** is the professional choice.

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.
