Tungaloy VBMT160404-PS T9125 Insert

Universal Steel Finishing | CVD Coated Performance | Precision Copy Turning

What is the most reliable insert for precision profiling in steel?

The Tungaloy VBMT160404-PS T9125 is a high-performance CVD-coated carbide insert specifically designed for finishing and semi-finishing operations in steel. Utilizing Tungaloy's proprietary PremiumTec surface technology, the T9125 grade offers a smooth coating that minimizes chip adhesion and prevents micro-cracking. Its 35-degree rhombic geometry provides maximum clearance for intricate profiling, while the 0.4mm corner radius ensures sharp detail and exceptional surface Ra values. Combined with the -PS (Positive Sharp) chipbreaker, this insert maintains stable chip control even at low depths of cut, making it the primary choice for professional CNC machining.

T9125 CVD Coating

A thick TiCN + Al2O3 coating layer provides superior thermal resistance and wear protection, extending tool life in high-speed dry or wet cutting.

-PS Precision Chipbreaker

The positive high-rake design reduces cutting force and vibrations, ensuring high-dimensional accuracy on slender or complex workpieces.

PremiumTec Finish

The specialized post-coating treatment results in an ultra-smooth surface that prevents chips from sticking, leading to better surface finishes.

Professional Feedback

⭐⭐⭐⭐⭐ "Excellent Finish" - D. Miller, USA
"The surface finish on alloy steel is mirror-like. Tungaloy's T9125 never disappoints for high-precision finishing."

⭐⭐⭐⭐⭐ "Great Copying Insert" - L. Kowalski, Poland
"We use these for profiling complex shafts. The -PS breaker handles chip breaking perfectly even at shallow depths."

⭐⭐⭐⭐⭐ "Reliable Grade" - B. Schneider, Germany
"Consistent tool life. Beyond Li delivered authentic Japan-made inserts within days. Very satisfied."

⭐⭐⭐⭐⭐ "Sharp and Stable" - T. Sato, Japan
"The 0.4mm radius is very sharp. Essential for the high-precision finishing passes on our lathe."

⭐⭐⭐⭐⭐ "Value for Money" - G. Thompson, UK
"Higher tool life than our previous European supplier. T9125 stays sharp even under heat."

8. FAQ - Engineering Support

Q: Is T9125 suitable for heavy roughing?

A: T9125 is a general-purpose grade that can handle some roughing, but for heavy interrupted roughing, we recommend T9235.

Q: Why choose the -PS breaker for finishing?

A: The -PS is designed for light cutting forces. It prevents vibrating and workpiece chatter, ensuring high-quality surface integrity.

Q: Can this insert be used on aluminum?

A: No. For aluminum and non-ferrous materials, we recommend uncoated sharp grades like the TH10 or cermet grades for better finish.

Machinist Tip: Maximizing Surface Finish

For the best surface finish with the **VBMT160404-PS**, keep your feed rate at approximately 0.1mm/rev. The **0.4mm corner radius** is excellent for precision, but ensuring high cutting speeds will activate the **PremiumTec** coating for a cleaner chip flow. **Tungaloy Japan** - Excellence in 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.
