Tungaloy SCMT120404-24 NS9530 Insert

Mirror Steel Finishing | 24 Precision Breaker | NS9530 Cermet Grade

How to achieve a mirror finish on steel using cermet inserts?

The Tungaloy SCMT120404-24 NS9530 is a high-performance square cermet turning insert designed for high-speed finishing of carbon and alloy steels. Featuring the advanced NS9530 cermet grade, this insert provides superior chemical stability and resistance to oxidation, allowing for incredibly smooth surface finishes that often eliminate the need for secondary grinding. The 24 chipbreaker is precision-engineered for light finishing depths, ensuring excellent chip evacuation even at high cutting speeds. Made in Japan, this CNC turning insert is the industry standard for high-precision components in the automotive and aerospace sectors.

Advanced NS9530 Grade

A premier cermet grade that prevents material adhesion (BUE), maintaining a sharp edge for extended periods during high-speed finishing.

24 Chipbreaker Design

Specifically tuned for light-duty finishing passes, offering low cutting resistance and superior dimensional accuracy.

High Thermal Stability

Cermet's ceramic-metal hybrid structure ensures the tool maintains its hardness at high surface speeds where carbide would fail.

Global Verified Reviews

⭐⭐⭐⭐⭐ "Mirror Surface Success" - Mark H., Germany
"The Ra value we achieved on 1045 steel was incredible. These SCMT cermet inserts perform perfectly at high speeds."

⭐⭐⭐⭐⭐ "Exceptional Life" - Tanaka S., Japan
"Continuous finishing of automotive axles. The NS9530 grade keeps the dimensions stable part after part."

⭐⭐⭐⭐ "Great Chip Control" - James B., USA
"Finally an insert that doesn't bird-nest during finishing. The -24 breaker is well-tuned."

⭐⭐⭐⭐⭐ "Original Quality" - G. Rossi, Italy
"Received genuine Tungaloy packaging. Performance is far superior to generic carbide for final passes."

⭐⭐⭐⭐⭐ "Perfect for Alloy Steel" - Lim Wei, Singapore
"Using on 4140 steel. Beautiful finish and very low tool wear at 200m/min."

8. FAQ - Finishing Solutions

Q: Can I use this for roughing steel?

A: No. Cermet is designed for high-speed finishing. For heavy roughing, please use Tungaloy AH series carbide grades.

Q: Does cermet require special tool holders?

A: No, it fits standard ISO holders like the SSDCN series for SCMT 1204 inserts.

Q: Is NS9530 better than coated carbide?

A: For high-speed finishing where a superior surface finish is required, NS9530 cermet is significantly better due to its chemical stability.

Expert Insight: The Cermet Advantage

In high-precision finishing, cermet is superior because it resists "welding" of the workpiece material to the tool. The NS9530 grade allows for much higher cutting speeds while maintaining edge sharpness, ensuring your SCMT120404 inserts deliver a world-class mirror finish consistently.

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?
