Tungaloy TCMT16T304-24 T9125 Turning Insert

High-Speed Steel Machining | Premium T9125 CVD Carbide | 0.4mm Radius

Which turning insert is best for high-productivity steel finishing?

The Tungaloy TCMT16T304-24 T9125 is a premium triangular turning insert designed for the rigorous demands of ISO P (Steel) machining. Utilizing the world-renowned T9125 CVD coated carbide grade, this insert offers unparalleled wear resistance and thermal stability during high-speed operations. The -24 chipbreaker combined with a 0.4mm corner radius ensures precise chip control and excellent surface integrity. Engineered and Made in Japan, it is the professional choice for CNC machining centers seeking to reduce downtime and improve part quality.

T9125 Premium Coating

Advanced CVD coating technology provides a thick alumina layer for extreme heat resistance, allowing for higher cutting speeds in alloy steels without edge deformation.

-24 Precision Breaker

The -24 geometry is specifically designed for light-to-medium finishing, preventing chip entanglement and promoting stable cutting even at lower feed rates.

Robust Substrate

The specialized carbide substrate balances toughness and hardness, making it highly resistant to chipping and thermal cracking in continuous cutting.

3. Technical Specifications: Metric vs. Imperial

Parameter Metric (ISO) Imperial Equivalent
Cutting Edge Length (L) 16.5 mm TCMT 32.51
Inscribed Circle (IC) 9.525 mm 3/8"
Thickness (S) 3.97 mm 5/32"
Corner Radius (RE) 0.4 mm 1/64"

Recommended Cutting Parameters (T9125)

  • Cutting Speed (Vc): 120 - 300 m/min
  • Feed Rate (f): 0.05 - 0.25 mm/rev
  • Depth of Cut (ap): 0.2 - 2.5 mm

*Machinist Note: T9125 is optimized for dry machining or air cooling. If using liquid coolant, ensure high pressure and volume to avoid thermal shock to the CVD coating.*

4. Product Applications

  • High-speed finishing of carbon and alloy steels.
  • Final machining of automotive shafts and gears.
  • Boring operations for heavy industrial components.
  • Suitable for both continuous and light interrupted cuts.

5. Tool Compatibility

Compatible with standard Tungaloy / ISO tool holders designed for TCMT 16T3 size inserts (3/8" Inscribed Circle). This includes various external turning shanks and large diameter boring bars.

8. FAQ - Turning Technical Support

Q: Is T9125 suitable for stainless steel?

A: While T9125 can cut stainless, it is optimized for ISO P (Steel). For stainless steel (ISO M), Tungaloy's AH series is generally recommended.

Q: What is the benefit of the CVD coating on this insert?

A: The CVD coating on T9125 provides a thick, wear-resistant layer that protects the carbide substrate from the extreme temperatures generated at high cutting speeds.

Q: Does this fit my boring bar?

A: If your boring bar pocket is designed for a TCMT 16T3 (3/8" IC) triangular insert, this will fit perfectly. Check your tool holder model number for verification.

Expert Tip: Carbide vs. Cermet

Choose **T9125 Carbide** for heavy productivity and versatility in various steels. If your application requires an absolute mirror finish under very stable conditions, you might consider **NS9530 Cermet**. For consistent reliability, **Tungaloy Japan** remains the professional choice.

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.
