Tungaloy TCMT16T308-PS T9125 Turning Insert

Industrial CVD Coated Carbide | T9125 All-Rounder Steel Grade | 0.8mm Radius

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

The Tungaloy TCMT16T304-PS T9125 is a high-performance triangular indexable insert designed for the semi-finishing and finishing of ISO P (Steel) materials. Featuring the advanced T9125 CVD coating, this insert is widely regarded as the "all-rounder" for steel machining, offering a perfect synergy of wear resistance and edge toughness. The 0.8mm corner radius (08) provides a stronger cutting edge than smaller variants, allowing for higher feed rates and stable performance in light interrupted cuts. The -PS (Power Sharp) chipbreaker ensures excellent chip evacuation at light to medium depths of cut. 100% Made in Japan, it is the professional choice for CNC shops prioritizing tool life and reliability.

T9125 Versatile Grade

Developed with PremiumTec surface technology, T9125 provides a smooth coating surface that resists built-up edge (BUE) and crater wear. It is the first choice for a wide variety of steel alloys.

-PS Precision Breaker

The Power Sharp geometry features a positive rake to reduce cutting resistance. It prevents work-hardening and ensures stable chip breaking during finishing passes.

0.8mm Robust Edge

The 0.8mm radius (08) offers superior edge strength for general-purpose turning, allowing for higher productivity and faster metal removal rates (MRR).

Expert Cutting Parameters (T9125 Grade)

Cutting Speed (Vc): 100 - 300 m/min (Balanced productivity)
Feed Rate (f): 0.08 - 0.25 mm/rev (High productivity finishing)
Depth of Cut (ap): 0.2 - 2.0 mm

*Machinist Advice: T9125 is the versatile choice. For slightly interrupted cuts in steel, the 0.8mm radius provides the edge strength needed to avoid chipping.*

4. Primary Applications

General turning of carbon and alloy steels (ISO P).
Profiling and external finishing where Ra requirements are high.
Boring operations for medium diameter holes.
Effective in high-speed and semi-interrupted machining conditions.

5. Equipment Compatibility

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

8. FAQ - Professional Support

Q: Is T9125 better than T9115 for finishing?

A: T9115 is for absolute high-speed stability in continuous cuts. T9125 is the better choice for general steel turning, providing more toughness for varied workloads.

Q: What is the benefit of the 0.8mm radius over 0.4mm?

A: The 0.8mm radius (08) offers a stronger cutting edge and allows for higher feed rates, making it more productive for general-purpose finishing.

Tech Tip: T9125 for Steel Machining

For the widest range of steel turning applications, the **T9125 CVD grade** is the industry standard. Its superior thermal resistance and edge toughness ensure that you spend more time cutting and less time changing tools. **Tungaloy Japan** - Professional grade CNC 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.
