Tungaloy TNMG160408R-S T9125 Turning Insert

Right-Hand High-Efficiency Machining | T9125 CVD Grade | RS Finishing Geometry

What is the most reliable right-hand insert for high-speed steel finishing?

The Tungaloy TNMG160408R-S T9125 is a premium, right-hand (R) oriented turning insert engineered for high-stability finishing of carbon and alloy steels. Utilizing the world-renowned T9125 CVD coated carbide grade, it offers an industry-leading balance of wear resistance and fracture toughness. The -S (RS) chipbreaker is specifically designed for light-duty finishing passes, ensuring excellent chip evacuation and preventing surface marring. With a 0.8mm corner radius for enhanced edge strength, this 100% Made in Japan tool is the benchmark for B2B industrial CNC operations.

T9125 CVD Coating

Equipped with a thick Al2O3 layer for superior heat insulation. This prevents plastic deformation and crater wear during high-velocity continuous cutting of steel.

RS (-S) Finishing Geometry

A sharp finishing geometry that significantly reduces cutting resistance, allowing for vibration-free operations and mirror-like surface finishes.

Right-Hand (R) Designation

Optimized for right-hand tool holder configurations, ensuring the chip flow is directed away from the workpiece during precision turning.

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

Technical Feature Metric (ISO) Imperial (ANSI)
Standard Model TNMG160408R-S TNMG 332R-S
Inscribed Circle (IC) 9.525 mm 3/8"
Thickness (S) 4.76 mm 3/16"
Corner Radius (RE) 0.8 mm 1/32"

Recommended Finishing Parameters (Steel)

  • Cutting Speed (Vc): 150 - 320 m/min
  • Feed Rate (f): 0.10 - 0.35 mm/rev
  • Depth of Cut (ap): 0.2 - 1.5 mm

*Pro-Tip: For optimal life, maintain constant cutting speeds. T9125 grade's Al2O3 coating functions best under high thermal loads during high-speed finishing.*

4. Primary Applications

  • Precision finishing of carbon and alloy steels.
  • Continuous turning operations in mass production.
  • Final dimensioning of gears, axles, and mechanical shafts.
  • Boring and finishing operations requiring tight tolerances.

5. Tool Compatibility

Pairs perfectly with standard ISO/ANSI TNMG 1604 pockets. Optimized for Right-Hand (RH) tool holders such as MTJNR, WTJNR, or DTGNR. Fully compatible with Haas, Mazak, and Mori Seiki lathes.

Machinist Feedback from Worldwide

⭐⭐⭐⭐⭐ "Extremely Stable Finish" - James K., USA
"The T9125 grade is incredibly stable. Used this for finishing 4140 steel, and the surface Ra was perfect. Great edge life."

⭐⭐⭐⭐⭐ "Original Quality stock" - Markus D., Germany
"Exactly as described. Authentic Tungaloy boxes. The 0.8mm radius is strong and the chipbreaker prevents any tangling."

⭐⭐⭐⭐ "Great Chip Control" - Hiroshi S., Japan
"Consistent performance in alloy steel. The right-hand geometry is perfect for our standard tool blocks. Very reliable."

⭐⭐⭐⭐⭐ "Reliable B2B Partner" - Carlos M., Mexico
"Beyond always provides original stock. Fast shipping to our facility. Tungaloy's CVD coating is superior for steel."

⭐⭐⭐⭐⭐ "Exceptional Surface Luster" - Alistair M., UK
"Precise radius and very sharp cutting edge. Excellent value for original Tungaloy parts. Surface finish is top-notch."

8. FAQ - Professional Support

Q: What does the 'R' in the model number stand for?

A: The 'R' stands for Right-Hand orientation. This specifies the cutting direction and chipbreaker geometry for optimal performance in RH tool holders.

Q: Can I use T9125 for stainless steel?

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

Q: Is this insert compatible with standard boring bars?

A: Yes, it fits any standard ISO/ANSI boring bar that accepts a TNMG 1604 (33x) size pocket.

Tech Tip: Optimizing CVD Efficiency

To maximize tool life with **T9125**, maintain a high cutting speed to prevent built-up edge (BUE). High speeds allow the Al2O3 coating to operate 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.
