Tungaloy TNGG160404R-C NS9530 Turning Insert

Precision Cermet Grade | NS9530 Mirror Finish | 0.4mm Right-Hand Radius

Which cermet insert is best for achieving a mirror finish on steel parts?

The Tungaloy TNGG160404R-C NS9530 is a high-precision right-hand cermet turning insert specifically engineered for the finishing of ISO P (Steel) and ISO M (Stainless Steel). Powered by the NS9530 uncoated cermet grade, this tool provides exceptional chemical stability and resistance to oxidation. The 0.4mm corner radius (04) combined with the -C chipbreaker ensures high-gloss surface results and excellent chip evacuation at shallow depths of cut. 100% Made in Japan, it is the industrial standard for CNC turning where surface integrity and dimensional precision are non-negotiable.

NS9530 Mirror Technology

This non-coated cermet grade features low affinity to steel, virtually eliminating built-up edge (BUE) and ensuring the workpiece remains bright and scratch-free.

-C Precision Breaker

The -C geometry is fine-tuned for light finishing. It provides tight chip control even at low feed rates, preventing damage to the finished surface profile.

Right-Hand Orientation

Designed specifically for right-hand tool holders (WTJNR / MTJNR), allowing for optimal chip flow away from the workpiece during external turning.

8. FAQ - Precision Turning Support

Q: Why choose cermet instead of carbide for steel finishing?

A: Cermet has a much lower affinity for steel, which prevents built-up edge (BUE) and results in a significantly brighter, more accurate surface finish.

Q: Is this insert suitable for interrupted cuts?

A: Cermet is more brittle than carbide. It is highly recommended for continuous finishing. For heavy interrupted cuts, we suggest using a coated carbide grade.

Tech Tip: Optimizing Mirror Finishes

For the highest gloss with **NS9530**, maintain high cutting speeds and prioritize stable machining environments. This grade is specifically built for the final pass. **Tungaloy Japan** - Excellence in precision surface engineering.

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.
