Tungaloy VCMT160408-PS T9125 Turning Insert

General Purpose Steel Machining | Premium CVD Grade | -PS Sharp Finishing Geometry

Which insert is most reliable for general steel turning and interrupted finishing?

The Tungaloy VCMT160408-PS T9125 is a high-versatility 35° rhombic insert engineered for workshops that demand stability across a wide range of steel machining tasks. The T9125 grade combines a tough carbide substrate with a specialized CVD coating, making it the primary choice for P20-P35 steel applications involving both continuous and light interrupted cuts. Featuring the -PS (Positive Sharp) chipbreaker, it reduces cutting resistance and ensures excellent chip evacuation at shallow depths of cut, providing a high-gloss finish on alloy and carbon steels with a stronger 0.8mm corner radius for increased edge stability.

Finishing

T9125 Tough CVD Grade

Designed for high-stability machining in P25 steel. Resists thermal cracking and fracture during slightly interrupted cuts, extending tool life in non-ideal setups.

-PS Sharp Edge

The positive geometry reduces tool pressure, minimizing work hardening and workpiece vibration. Perfect for achieving high Ra surface quality.

0.8mm Radius Strength

The 160408 designation provides a robust corner radius that allows for higher feed rates while maintaining structural integrity against chipping.

Global Customer Reviews

⭐⭐⭐⭐⭐ "Workhorse Grade" - Mark R., USA
"T9125 is my daily driver for steel. The 0.8mm radius on the VCMT160408 is tough enough for the occasional bump without losing the edge."

⭐⭐⭐⭐⭐ "Mirror Finish" - Dieter S., Germany
"The -PS geometry provides a clean, glossy surface even on alloy steels. Very reliable for our shaft production."

⭐⭐⭐⭐ "Great Stability" - Luca V., Italy
"Consistent tool life across every box. We push these at 250m/min and the CVD coating holds up beautifully."

⭐⭐⭐⭐⭐ "Reliable B2B Supplier" - T. Nakamura, Japan
"Authentic Tungaloy parts. Fast shipping to Tokyo. The technical support here is exceptional."

Technical FAQ

Q: Can I use T9125 for stainless steel?

A: While primarily a steel grade (P25), it can perform in some ferritic stainless applications. For dedicated stainless work, we recommend the AH600/AH700 series.

Q: What is the optimal ap for the -PS breaker?

A: The -PS is a finishing breaker. It performs best at depths of cut between 0.3mm and 1.5mm.

Q: Is this insert suitable for dry machining?

A: The T9125 CVD coating is heat-resistant, but coolant is highly recommended for finishing to ensure superior surface quality and chip evacuation.

Machinist Tip: Edge Preparation

When using the **T9125** grade on harder alloys, ensure your spindle speed (Vc) is high enough to activate the CVD coating's self-lubricating properties. This reduces built-up edge (BUE) and significantly improves finish Ra. **BEYOND CNC** - Reliability in Every Edge.

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?

According to our shipping policy, orders are typically processed and shipped within 1–3 business days after confirmation. Delivery generally takes 5–20 business days, depending on your destination and shipping method. Customs clearance or unforeseen delays may affect delivery times. A tracking number is sent by email after shipment.
