Tungaloy SCMT09T308-PS T9115 Insert

High-Speed Steel Finishing | -PS Precision Breaker | T9115 Premium CVD Grade

What makes SCMT09T308-PS the best choice for steel finishing?

The Tungaloy SCMT09T304-PS T9115 is a high-performance square carbide turning insert specifically engineered for high-speed machining of ISO P (Steel) materials. Featuring the advanced T9115 CVD coating, this grade offers unparalleled wear resistance and stability 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 optimized for maximum productivity in CNC turning centers.

T9115 CVD Coating

Multi-layered CVD coating with high Al2O3 content provides an exceptional thermal barrier, allowing for high cutting speeds without edge deformation.

-PS High-Speed Breaker

Designed for high-speed finishing. It effectively curls chips at light depths of cut, preventing workpiece scratching and bird-nesting.

Enhanced Edge Strength

The 0.8mm corner radius provides a perfect balance between surface finish and edge durability for semi-finishing tasks.

Global Machinist Feedback

⭐⭐⭐⭐⭐ "High Speed Master" - James W., USA
"T9115 is incredible. I ran this at 420 m/min on 4140 steel and the finish was like glass. The 0.8 radius is very strong."

⭐⭐⭐⭐⭐ "Perfect Chip Control" - K. Schmidt, Germany
"The -PS breaker handles the chips perfectly on our CNC lathes. No more tangled nests during finishing passes."

⭐⭐⭐⭐ "Very Durable" - M. Sato, Japan
"Consistent results every time. Tungaloy quality is unmatched for high-volume automotive part production."

⭐⭐⭐⭐⭐ "Original Packaging" - F. Rossi, Italy
"Genuine Japanese inserts. Shipping was fast and the technical advice from the seller helped a lot."

⭐⭐⭐⭐⭐ "Top Performance" - Lim H., Singapore
"The Ra value we get with SCMT09T308 is amazing. Excellent stability across hundreds of parts."

8. FAQ - Professional Support

Q: Is T9115 better than T9215?

A: T9115 is a classic premium CVD grade with a proven track record for high-speed finish turning. T9215 is the newer generation, but T9115 remains a global favorite for its predictable wear.

Q: Can I use this for stainless steel?

A: SCMT-PS T9115 is optimized for ISO P (Steel). For stainless steel (ISO M), we recommend AH630 or T6100 series grades.

Q: Will this fit my standard SSDCN holder?

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

Machinist Tip: Why CVD T9115?

The T9115 CVD grade uses a thick Al2O3 layer that acts as a heat shield for the carbide substrate. This is why it performs best at high surface speeds (Vc). If you see edge deformation, increase your RPM—this insert is built to handle the heat of high-production steel finishing.

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.

When will my order ship and arrive?
