Tungaloy DNMG110404-11 NS9530 Turning Insert

High-Gloss Steel Finishing | Premium NS9530 Cermet | Made in Japan

How can I achieve a mirror finish on carbon steel parts?

The Tungaloy DNMG110404-11 NS9530 is a high-performance cermet turning insert specifically designed for the high-speed finishing of steel. Unlike traditional carbide, the NS9530 cermet grade offers exceptional chemical stability and resistance to oxidation, which prevents built-up edge and ensures a high-gloss, "mirror-like" surface finish. The -11 chipbreaker is a specialized geometry that excels in chip control during light depths of cut, providing stable precision machining even at elevated speeds. This Japan-made indexable turning tool features a 0.4mm corner radius, making it the ideal CNC machining choice for tight tolerances and intricate profiles. By integrating this long-tail keywords optimized finishing insert into your production, you can eliminate the need for secondary grinding processes and maximize tool life.

Recommended Cutting Parameters (NS9530)

  • Cutting Speed (Vc): 100 - 300 m/min (Recommended: 200 m/min)
  • Feed Rate (f): 0.05 - 0.25 mm/rev
  • Depth of Cut (ap): 0.2 - 1.5 mm

*Pro Tip: Cermets thrive on speed. Maintain a high Vc to maximize surface gloss and prevent built-up edge.*

Customer Feedback

⭐⭐⭐⭐⭐ "Amazing Surface Finish" - J. Miller, USA
"I used these for the final pass on 1018 steel. The finish is incredible, almost looks like it was polished by hand."

⭐⭐⭐⭐⭐ "Japan Quality Always" - K. Sato, Japan
"Very stable dimensions even after long runs. NS9530 is a very reliable cermet grade for our CNC lathes."

⭐⭐⭐⭐ "Great for Light Finishing" - B. Laurent, France
"Excellent chip breaking at shallow depths. I highly recommend for small precision components."

⭐⭐⭐⭐⭐ "No Built-up Edge" - R. Rossi, Italy
"This cermet insert stays clean. I pushed the speed to 250m/min and it handled it beautifully. Reduced our cycle times significantly."

⭐⭐⭐⭐⭐ "Consistent Performance" - S. Lee, South Korea
"The tolerance on these inserts is very tight. Swapping inserts doesn't change our offset. High efficiency for batch production."

Technical Tooling Q&A

Q: Is cermet better than carbide for finishing?

A: Yes, for light finishing. Cermets (like NS9530) have higher wear resistance and chemical stability, which results in a much better surface finish on steel.

Q: Should I use coolant with this insert?

A: Cermets can be used with or without coolant. However, if using coolant, ensure the flow is consistent to avoid thermal cracking due to heat fluctuations.

Q: What is the benefit of the -11 chipbreaker?

A: The -11 geometry is specifically tuned for light cutting and finishing, ensuring excellent chip control even at low feed rates.

Material Comparison Tip: Cermet vs. CVD Carbide

While CVD Carbide (like T9125) is the workhorse for heavy turning, Cermet (NS9530) is the master of the finishing pass. Cermet provides higher chemical resistance, meaning it won't "weld" to the steel, keeping your part surfaces smooth and shiny.

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.

When will my order ship and arrive?

According to our shipping policy, orders are typically processed and shipped within 1–3 business days after confirmation. Delivery generally takes 5–20 business days, depending on your destination and shipping method. Customs clearance or unforeseen delays may affect delivery times.
