Tungaloy SCMT09T304-PS T9115 Insert

High-Speed Steel Machining | -PS Precision Breaker | T9115 CVD Grade

What is the best carbide insert for high-speed finishing of steel?

The Tungaloy SCMT09T304-PS T9115 is a high-performance square carbide turning insert specifically engineered for the high-speed processing of ISO P (Steel) materials. Featuring the advanced T9115 CVD coating, this grade offers unparalleled wear resistance and plastic deformation resistance at high temperatures. The -PS chipbreaker provides a positive rake angle designed for finishing to light-medium cutting, ensuring exceptional surface quality and efficient chip evacuation. Made in Japan, this insert is the industry's go-to for maximizing productivity in CNC turning centers.

Advanced T9115 Grade

A dedicated CVD grade with high aluminum content in the Al2O3 layer, providing extreme heat resistance for high-speed (Vc) operations.

-PS Finishing Breaker

Optimized for finishing. The sharp edge and positive geometry prevent built-up edge and lower the cutting force on small lathes.

PremiumTec Surface

Tungaloy's special coating post-treatment smooths the surface to significantly reduce friction and chip welding during steel turning.

Global Verified User Reviews

⭐⭐⭐⭐⭐ "Extreme Speed" - Robert K., USA
"T9115 is incredible for high-speed passes. I've pushed it to 400 m/min on 1045 steel and the edge stays sharp forever."

⭐⭐⭐⭐⭐ "Great Chip Control" - L. Schneider, Germany
"The -PS breaker handles the chips perfectly on our CNC lathes. No more bird-nesting on finish passes."

⭐⭐⭐⭐ "Consistently Sharp" - S. Tanaka, Japan
"Excellent quality from Tungaloy. Consistent results over long batches of precision parts."

⭐⭐⭐⭐⭐ "Top B2B Supplier" - P. Rossi, Italy
"Genuine Japan stock. Shipping to Europe was very fast. CNCHome-Beyond is our primary tool source."

⭐⭐⭐⭐⭐ "Excellent Service" - B. Lim, Singapore
"Fast delivery and original packaging. Performance in semi-finishing alloy steel is top tier."

8. FAQ - Professional Support

Q: Is T9115 better than T9125?

A: T9115 is optimized for higher cutting speeds and continuous finish cuts. T9125 is a better all-rounder for general medium cutting with light interruptions.

Q: Can I use this for stainless steel?

A: T9115 is specifically for ISO P (Steel). For stainless steel (ISO M), we recommend the AH series or T6100 series grades.

Q: Will this fit my standard SSDCN holder?

A: Yes, it is a standard ISO SCMT 09T3 size and is perfectly compatible with SSDCN series holders.

Expert Tip: Why T9115 for High-Speed Turning?

The T9115 CVD grade is designed to withstand the crater wear that occurs at extreme cutting speeds. If your machine can handle the RPM, switching to T9115 allows you to drop your cycle times significantly without sacrificing tool life. For finishing alloy steels, the SCMT09T304-PS is the ultimate efficiency tool.

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.
