Tungaloy TNMG220404R-S T9125 Turning Insert

Professional Right-Hand Machining | T9125 CVD Technology | RS Finishing Geometry

What is the best 22mm right-hand insert for high-speed steel finishing?

The Tungaloy TNMG220404R-S T9125 is a premium, industrial-grade turning insert designed for specialized right-hand (R) machining cycles. Engineered for precision finishing of carbon and alloy steels, this 22mm size insert provides maximum rigidity and stability in heavy-duty CNC environments. Featuring the T9125 CVD coated carbide grade, it excels in heat resistance and edge retention. The -S (RS) chipbreaker is specialized for light-duty finishing, delivering exceptional chip control and a superior surface finish. 100% Made in Japan, it is the standard for high-performance B2B machining applications.

T9125 CVD Grade

Designed with a thick Al2O3 layer for extreme heat resistance. This grade prevents crater wear and plastic deformation during high-speed continuous turning.

RS (-S) Finishing Chipbreaker

A sharp, precision-ground geometry that reduces cutting forces. It manages chips effectively even at low depths of cut, ensuring a mirror-like finish.

22mm Heavy Rigidity

The TNMG 22 size offers a larger contact area for the tool holder, significantly reducing vibration and improving accuracy in larger workpieces.

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

Technical Feature Metric (ISO) Imperial (ANSI)
Standard Model TNMG220404R-S TNMG 431R-S
Inscribed Circle (IC) 12.7 mm 1/2"
Thickness (S) 4.76 mm 3/16"
Corner Radius (RE) 0.4 mm 1/64"

Recommended Finishing Parameters (Steel)

  • Cutting Speed (Vc): 150 - 320 m/min
  • Feed Rate (f): 0.05 - 0.20 mm/rev
  • Depth of Cut (ap): 0.2 - 1.5 mm

*Pro-Tip: Maintaining high cutting speeds with T9125 grade provides peak luster. High-pressure coolant is recommended for deep-finishing applications.*

4. Primary Applications

  • Precision finishing of carbon and alloy steels (P15-P30).
  • Final dimensioning of large diameter shafts and valves.
  • Boring operations requiring right-hand tool rotation.
  • Automotive components with tight tolerance requirements.

5. Tool Compatibility

Fits all standard ISO/ANSI TNMG 2204 tool holders. Optimized for Right-Hand (RH) configurations like MTJNR or WTJNR. Compatible with DMG Mori, Mazak, and Okuma CNC machines.

Customer Feedback from Global Operations

⭐⭐⭐⭐⭐ "Incredible Stability" - James K., USA
"The larger 22 size is rock solid. We use these for finishing 4140 steel shafts. The right-hand geometry is exactly what our CNC setup needed."

⭐⭐⭐⭐⭐ "Original Quality" - Markus D., Germany
"Exactly as described. Authentic Tungaloy boxes. The T9125 grade provides a very predictable wear pattern over long shifts."

⭐⭐⭐⭐ "Great Chip Management" - Hiroshi S., Japan
"Consistent results. The -S chipbreaker manages long-stringy chips perfectly even at shallow depths of cut."

⭐⭐⭐⭐⭐ "Reliable B2B Partner" - Carlos M., Mexico
"Beyond always provides original stock. Fast shipping to our factory. The technical data provided was very accurate for our setup."

⭐⭐⭐⭐⭐ "Excellent Finish" - Alistair M., UK
"Precise radius and very sharp cutting edge. The surface finish on our finished parts is mirror-like. Best value for Tungaloy."

8. FAQ - Machine Shop Support

Q: What is the benefit of the TNMG 22 size over the 16 size?

A: The TNMG 22 size offers a larger mass and seating area, which leads to better heat dissipation and significantly higher rigidity during finishing of larger workpieces.

Q: Can I use T9125 for stainless steel?

A: T9125 is optimized for carbon and alloy steels (P-group). For stainless steel finishing, Tungaloy's T6100 series or AH series grades are recommended.

Q: Why choose the -S chipbreaker?

A: The -S (RS) chipbreaker is specifically designed for light finishing. It reduces cutting resistance and prevents vibration, which is crucial for achieving high surface quality.

Tech Tip: Optimizing CVD Performance

To maximize tool life with **T9125**, maintain a high cutting speed to prevent built-up edge (BUE). High speeds allow the CVD coating to work at peak thermal efficiency. **Tungaloy Japan** - Engineering excellence for precision machining.

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.
