Tungaloy TPMT110304-PSS T9125 Insert

Premium T9125 CVD Grade | -PSS Precision Geometry | 0.4mm Radius

Which Tungaloy insert is best for high-speed steel finishing?

The Tungaloy TPMT110304-PSS T9125 is a high-performance triangular turning insert specifically balanced for the finishing of steel workpieces. Utilizing the T9125 CVD coating, this insert provides exceptional wear resistance and thermal stability during high-velocity cuts. The -PSS (Positive Sharp Small) chipbreaker is engineered to reduce cutting forces and manage chips effectively at shallow depths of cut, ensuring a high-quality surface finish and dimensional consistency. This Made in Japan tool is the industrial benchmark for ISO P25 steel applications.

T9125 CVD Coating

Advanced multi-layer CVD coating (TiCN+Al2O3) offers superior hardness and heat protection, ideal for high-speed continuous cutting in carbon and alloy steels.

-PSS Sharp Geometry

The 'Positive Sharp Small' geometry minimizes vibration and work hardening, making it the perfect choice for small diameter parts and precision finishing.

PremiumTec Treatment

Tungaloy's exclusive surface treatment improves chip evacuation and reduces friction, leading to longer tool life and predictable wear patterns.

Customer Reviews

⭐⭐⭐⭐⭐ "Excellent Finish" - David W., UK
"T9125 is surprisingly tough for a finishing grade. Used it on 4140 alloy steel and the surface finish was mirror-like."

⭐⭐⭐⭐⭐ "Great Chip Breaking" - Stefan G., Germany
"The -PSS geometry is perfect for our boring operations. No more bird-nesting chips around the tool."

⭐⭐⭐⭐⭐ "Reliable B2B Partner" - Raj V., India
"Authentic inserts and very fast shipping. The technical advice provided helped us reduce cycle time."

8. FAQ - Support for Professionals

Q: Can I use T9125 for stainless steel?

A: T9125 is optimized for steel (ISO P). For stainless steel (ISO M), we recommend Tungaloy's AH series or T6100 series grades for better results.

Q: Why choose 0.4mm radius instead of 0.8mm?

A: The 0.4mm radius (304) is ideal for finishing because it creates lower radial cutting forces, reducing chatter in slender workpieces.

Machining Tip: Steel Grade Optimization

The **T9125 CVD grade** thrives in high-speed, continuous cuts. To maximize the life of your **-PSS geometry**, maintain a consistent feed rate to keep the chips small and prevent edge wear. **Tungaloy Japan** - Excellence in Tooling.

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.
