Tungaloy DNMG150608-TM T9115 Turning Insert

High-Speed Steel Machining | Premium T9115 CVD Grade | Made in Japan

What is the best carbide insert for high-speed medium cutting of steel?

The Tungaloy DNMG150608-TM T9115 is a premium CVD coated carbide turning insert specifically engineered for high-efficiency machining of carbon and alloy steels. Utilizing the advanced T9115 grade, this insert features Tungaloy's "PremiumTec" surface technology, providing an ultra-smooth coating that reduces friction and prevents chips from welding to the edge. The 0.8mm corner radius provides a perfect balance between edge strength and surface finish. Combined with the -TM chipbreaker, it ensures stable chip control across a wide range of feed rates. With a reinforced 6.35mm thickness, this Japan-made indexable turning tool is the professional CNC machining choice for those demanding long tool life and rigidity in heavy-duty applications. Incorporating this long-tail keywords optimized insert into your shop ensures superior productivity and dimensional stability.

Corner Radius (RE) 0.8 mm 1/32 inch

Recommended Cutting Parameters (T9115)

  • Cutting Speed (Vc): 150 - 350 m/min (Standard Steels)
  • Feed Rate (f): 0.15 - 0.50 mm/rev
  • Depth of Cut (ap): 0.8 - 5.0 mm

*Pro Tip: The 1506 series thickness (6.35mm) allows for higher depth of cut without compromising tool stability compared to the thinner 1504 series.*

Feedback from Global Machinists

⭐⭐⭐⭐⭐ "Incredible Durability" - Mark R., USA
"Running these on alloy steel shafts. The T9115 grade handles the heat much better than our previous CVD inserts. Predictable tool life is a game changer for us."

⭐⭐⭐⭐⭐ "Stable and Reliable" - J. Müller, Germany
"Consistent results even at 320 m/min. The -TM chipbreaker works beautifully on carbon steel. Japan quality standard."

⭐⭐⭐⭐ "Great Chip Control" - Yuki H., Japan
"The chip evacuation is very clean during semi-finishing. Excellent stability in our high-speed automated lathe."

⭐⭐⭐⭐⭐ "Excellent Surface Finish" - Antonio P., Italy
"For a medium cutting insert, the finish is outstanding. The 0.8mm radius is strong and gives us the precision we need."

⭐⭐⭐⭐⭐ "Production Workhorse" - Sarah D., UK
"These 150608 inserts are the backbone of our CNC turning section. High metal removal rates and reliable performance."

Technical Tooling Q&A

Q: Why use DNMG1506 over DNMG1504?

A: The 1506 series is thicker (6.35mm vs 4.76mm). This provides superior vibration dampening and heat dissipation, ideal for heavier cuts and increased tool stability.

Q: Is T9115 grade suitable for stainless steel?

A: T9115 is optimized for general steel. For stainless steel, Tungaloy AH series or specialized PVD grades are usually recommended to avoid work hardening.

Q: Which tool holder fits this insert?

A: It fits standard ISO holders like DDJNR/L or PDJNR/L using the 15mm seat size. Ensure your holder is designed for 6.35mm thickness.

Expert Choice: Premium CVD Coatings

For high-speed continuous turning in steel, CVD Coated Carbide (T9115) is superior due to its thermal stability. This protects your indexable turning tool from edge deformation, ensuring your CNC machining remains cost-effective.

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.
