Description

Tungaloy TNMG160408-TM T9115 Turning Insert

Professional High-Speed Steel Grade | TM Medium-Cutting | 0.8mm Stable Edge

What is the best carbide insert for high-productivity steel turning?

The Tungaloy TNMG160408-TM T9115 is a premium, double-sided triangular insert engineered for high-speed machining of carbon and alloy steels. Built with the T9115 CVD (Chemical Vapor Deposition) coating, it features Tungaloy's "PremiumTec" surface technology which provides exceptional crater wear resistance and thermal stability. The -TM chipbreaker is specifically designed for medium cutting applications, offering a balance of low cutting force and superior chip evacuation. 100% Made in Japan, this insert is the industrial choice for high-volume CNC production.

T9115 High-Velocity Grade

Specifically optimized for P15-grade steel machining. It thrives in high-temperature zones, maintaining edge sharpness longer than general-purpose grades.

TM All-Rounder Chipbreaker

The geometry is perfected for medium depths of cut. It effectively breaks chips to prevent tool wrapping and workpiece scratching.

0.8mm Corner Radius

Provides a robust cutting edge suitable for slightly higher feed rates and increased durability during semi-roughing to finishing stages.

3. Technical Data: Metric (ISO) vs. Imperial (ANSI)

Technical Feature Metric (ISO) Imperial (ANSI)
Standard Model TNMG160408-TM TNMG 332-TM
Inscribed Circle (IC) 9.525 mm 3/8"
Thickness (S) 4.76 mm 3/16"
Corner Radius (RE) 0.8 mm 1/32"

Recommended Cutting Parameters (Steel)

  • Cutting Speed (Vc): 180 - 380 m/min (High speed recommended)
  • Feed Rate (f): 0.15 - 0.45 mm/rev
  • Depth of Cut (ap): 0.8 - 4.5 mm

*Pro-Tip: T9115 is designed for speed. Maintaining a high surface speed (Vc) prevents built-up edge and improves the finish on carbon steels.*

4. Primary Applications

  • Carbon Steel (S45C, 1045) turning.
  • Alloy Steel (4140, SCM440) machining.
  • Mass production of automotive and hydraulic components.
  • Excellent for continuous cutting and high RPM operations.

5. Tool Compatibility

Standard ISO TNMG 1604 pockets. Optimized for use with MTJNR/L, WTJNR/L, or DTGNR/L tool holders. Compatible with Haas, Mazak, Doosan, and DMG Mori CNC machines.

Global Shop Feedback

⭐⭐⭐⭐⭐ "Speed Master" - James K., USA
"T9115 is incredible at high SFM. Our cycle time on 1045 steel shafts dropped by 20% compared to our previous brand."

⭐⭐⭐⭐⭐ "Authentic Quality" - Markus D., Germany
"Exactly as described. Authentic Tungaloy Japan inserts in sealed packs. The TM chipbreaker is very reliable for job shop work."

⭐⭐⭐⭐ "Consistent Tool Life" - Hiroshi S., Japan
"We run these lights-out. The wear pattern is extremely predictable, which is exactly what we need for automation."

⭐⭐⭐⭐⭐ "Great Service" - Carlos M., Mexico
"Beyond helped us find the right cutting speeds. Fast shipping and the inserts perform perfectly on our Mazak lathes."

⭐⭐⭐⭐⭐ "Stable and Strong" - Alistair M., UK
"The 0.8mm radius is very robust. Even with light scale on the workpiece, T9115 holds the edge well."

8. FAQ - Professional Support

Q: Can I use T9115 for machining stainless steel?

A: T9115 is optimized for Steel (P). For stainless steel (M), we strongly recommend the Tungaloy T6130 grade which handles heat and work-hardening better.

Q: Why choose the TM chipbreaker?

A: The -TM is the standard medium-cutting chipbreaker. It provides the most versatile performance across a wide range of feed rates and cutting depths.

Q: What is the benefit of CVD coating over PVD?

A: CVD coatings (like T9115) are thicker and offer much higher heat resistance, making them ideal for high-speed continuous turning in steel.

Tech Tip: Steel Machining Efficiency

The **T9115 CVD grade** is engineered with a thick Al2O3 layer that acts as a thermal barrier. In high-speed turning, heat stays in the chip, not the tool. Always verify your spindle limit to reach optimal **Vc** for mirror finishes. **Tungaloy Japan** - Excellence in 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.
