Tungaloy VCMT160408-24 NS9530 Turning Insert

Precision High-Gloss Finishing | Premium Cermet Grade | -24 Sharp Geometry

Which insert is most effective for achieving mirror-quality surface finishes on steel components?

The Tungaloy VCMT160408-24 NS9530 is a high-performance 35° rhombic insert specifically engineered for the final finishing stages of steel machining. Utilizing the advanced NS9530 Cermet grade, this insert offers superior chemical stability and resistance to oxidation compared to standard carbide. The -24 chipbreaker is designed with a sharp cutting edge and positive rake angle to minimize cutting resistance, preventing work hardening and ensuring a high-gloss surface finish. With its robust 0.8mm corner radius, it provides a perfect balance between surface Ra and edge strength.

Geometry

NS9530 Advanced Cermet

A premium uncoated cermet grade that prevents metal adhesion (built-up edge). It maintains a sharp cutting edge much longer than carbide during high-speed finishing, resulting in consistent dimensional accuracy.

-24 Precision Chipbreaker

Specifically tuned for light finishing. Its geometry forces effective chip breaking even at low feed rates and shallow depths of cut, protecting the workpiece from "bird-nesting" scratches.

High Thermal Stability

Excellent for dry machining. The NS9530 grade thrives in high-temperature environments, making it ideal for high-speed CNC applications where coolant use is restricted or undesirable.

Professional User Feedback

⭐⭐⭐⭐⭐ "Mirror Surface Found" - Mark R., USA
"We use NS9530 for the final pass on 4140 steel. The finish is so glossy we eliminated a secondary polishing step. Incredible stability."

⭐⭐⭐⭐⭐ "No Built-up Edge" - Dieter W., Germany
"Consistent Ra values throughout the whole production run. The -24 geometry breaks chips perfectly at low feeds."

⭐⭐⭐⭐ "Great Stability" - Giovanni L., Italy
"Great choice for dry finishing. The corner radius holds up well even at 300 m/min."

⭐⭐⭐⭐⭐ "Authentic Quality" - T. Yamamoto, Japan
"Genuine Tungaloy stock. Fast shipping to our factory and excellent technical support from the Beyond team."

Technical FAQ

Q: Can I use NS9530 for interrupted cuts?

A: Cermet is more brittle than carbide. While NS9530 is a tough grade, we recommend it primarily for continuous finishing to prevent micro-chipping.

Q: What is the benefit of the 0.8mm radius on this cermet insert?

A: The 0.8mm radius (VCMT160408) provides a stronger cutting edge and allows for slightly higher feed rates compared to the 0.4mm version while still maintaining excellent surface finish.

Q: Is coolant required for this grade?

A: Cermet performs exceptionally well in dry machining. If you use coolant, ensure it is high-pressure and consistent to avoid thermal shock.

Expert Tip: High-Gloss Control

For the best results with **NS9530**, increase your cutting speed (Vc) as you reduce the feed rate. This leverages the cermet's chemical stability to produce a mirror finish that standard carbide cannot match. **BEYOND CNC** - Reliability in Every Pass.

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.
