Tungaloy TCMT16T304-PS T9125 Turning Insert

Industrial CVD Coated Carbide | T9125 Versatile Steel Specialist | 0.4mm Radius

What is the most reliable carbide grade for versatile steel turning?

The Tungaloy TCMT16T304-PS T9125 is a high-performance triangular indexable insert engineered for the finishing and semi-finishing of ISO P (Steel) materials. Featuring the advanced T9125 CVD coating, this insert provides an exceptional balance of wear resistance and toughness, making it the "all-rounder" choice for both continuous and slightly interrupted cuts. The 0.4mm corner radius (04) and -PS (Power Sharp) chipbreaker are optimized for precision profiling and finishing, ensuring superior chip evacuation even at light depths of cut. 100% Made in Japan, it is the professional solution for CNC operations requiring consistent dimensional accuracy.

T9125 Versatile Grade

A specialized CVD grade using PremiumTec surface technology. It reduces built-up edge (BUE) and offers superior fracture resistance in varied steel alloys compared to T9115.

-PS Precision Breaker

The "Power Sharp" geometry features a highly positive rake angle. This minimizes cutting resistance and heat generation, which is essential for maintaining high-gloss surface finishes.

Industrial Durability

The triangular 7-degree positive relief design allows for low-force cutting, making it ideal for boring bars and long-reach applications where vibration control is critical.

Expert Cutting Parameters (T9125 Grade)

Cutting Speed (Vc): 120 - 320 m/min (Recommended for Alloy Steel)
Feed Rate (f): 0.05 - 0.20 mm/rev
Depth of Cut (ap): 0.2 - 1.5 mm

*Pro Tip: T9125 is the versatile grade. If you experience edge chipping on carbon steel, T9125 provides the toughness needed to handle slight surface irregularities.*

4. Primary Applications

Precision finishing of carbon, alloy, and tool steels.
High-speed continuous turning with light surface Ra needs.
Internal boring where low cutting resistance is mandatory.
Machining automotive shafts, pins, and hydraulic parts.

5. Tool Compatibility

Universal fit for TCMT 16T3 / TCMT 32.5 holders. Ideally paired with Tungaloy S-STFCR/L boring bars and STGCR/L external turning tools.

Feedback from Global CNC Specialists

⭐⭐⭐⭐⭐ "Predictable and Stable" - Hans W., Germany
"T9125 is my go-to grade for mixed steel batches. It handles variations in material hardness much better than others. Excellent surface Ra."

⭐⭐⭐⭐⭐ "Mirror Finish" - Robert T., USA
"Used these on our CNC lathe for finishing 4140 pins. The -PS breaker is amazing at light cuts—no stringy chips at all."

⭐⭐⭐⭐ "Fast Shipping" - Tan L., Malaysia
"Original Tungaloy Japan stock. The beyond team provided great technical parameters for my boring operation."

⭐⭐⭐⭐⭐ "Versatile Grade" - Marco F., Italy
"We run these at 250 m/min with great tool life. Very consistent across different carbon steel grades."

⭐⭐⭐⭐⭐ "Reliable B2B Partner" - Arjun M., India
"Genuine product in original sealed boxes. Significant reduction in tool cost per piece since switching to T9125."

8. FAQ - Professional Support

Q: When should I choose T9125 over T9115?

A: Use T9115 for maximum speed in continuous cutting. Choose T9125 if your setup has light vibration or if you are machining a variety of different steel alloys.

Q: What holder does this fit?

A: It fits any standard boring bar or turning tool designed for TCMT 16T3 (TCMT 32.5) size pockets.

Industrial Tip: CVD Coating Advantages

The **T9125 CVD grade** features a thick thermal barrier that allows for much higher cutting speeds than PVD grades. For high-volume steel finishing, this results in shorter cycle times and reduced tool wear. **Tungaloy Japan** - Engineering excellence for your CNC success.

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.
