Tungaloy TPGT16T304L-W15 NS9530 Insert

W15 High-Feed Wiper Geometry | NS9530 Cermet Grade | Ground Precision Finish

What is the best cermet insert for high-productivity finishing?

The Tungaloy TPGT16T304L-W15 NS9530 is a premium triangular turning insert designed specifically for high-speed precision finishing. Featuring the revolutionary W15 Wiper technology, this insert enables operators to maintain exceptional surface roughness (Ra) even when doubling standard feed rates. The NS9530 cermet grade offers incredible chemical stability, preventing built-up edge (BUE) and oxidation when machining carbon and alloy steels. 100% Made in Japan, it is the industrial benchmark for mirror-like surface quality and high dimensional accuracy.

W15 Wiper Advantage

The specialized wiper edge flattens the feed marks left by the tool radius, allowing you to increase productivity by up to 2x without compromising surface quality.

NS9530 Grade Stability

A non-coated titanium-based cermet that resists material adhesion. It maintains a sharp edge far longer than carbide in light finishing applications.

Mirror Finish Precision

As a G-class ground insert, it offers the highest repeatability for precision components in automotive and precision instrument industries.

What Machinists are Saying

⭐⭐⭐⭐⭐ "Surface Quality is Unreal" - James B., USA
"The W15 wiper really allows for faster feed rates while keeping a better surface finish than standard carbide. Tungaloy does it again."

⭐⭐⭐⭐⭐ "True Japan Quality" - Hiroshi K., Japan
"Original stock. The NS9530 is incredibly stable. No chip sticking even after 500 parts. Mirror finish all day."

⭐⭐⭐⭐ "Consistent & Fast" - Liam O., Ireland
"Doubled my feed and cut cycle time by 30%. Dimensional stability is perfect across batches. Great Ra."

⭐⭐⭐⭐⭐ "Reliable B2B Partner" - Sanjay G., India
"Very hard to find genuine TPGT16T304L-W15 sometimes, but Beyond always delivers authentic Tungaloy. High performance cermet."

⭐⭐⭐⭐⭐ "Best Ra I've seen" - Marco P., Italy
"Using this for finishing aerospace shafts. It gives a gloss finish that looks like it was ground. Highly recommended."

8. FAQ - Professional Support

Q: Can I use this for interrupted cuts?

A: Cermet is more brittle than carbide. It is highly recommended for continuous finishing. For heavy interruptions, consider a PVD coated carbide.

Q: What is the main benefit of the W15 wiper?

A: It flattens the peaks during the cutting process, allowing you to run at higher feed rates (increasing productivity) while maintaining the surface finish quality of a much slower feed.

Q: Is 'L' version right for my tool holder?

A: The 'L' stands for Left-hand. Ensure your tool holder and machine rotation are configured for left-handed cutting geometry.

Tech Insight: Why NS9530 Cermet?

The **NS9530 Cermet grade** is a composite material consisting of ceramic and metal. Its low affinity for steel prevents Built-Up Edge (BUE) and chemical wear. When paired with **W15 Wiper technology**, it provides a unique polishing effect during the turning process. **Tungaloy Japan** - Engineering Precision.

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.
