Tungaloy VBMT110308-PS NS9530 Insert

High-Gloss Cermet Finishing | 0.8mm Corner Radius | Mirror Surface Specialist

How can I get a mirror surface finish and stable tool life on steel?

The Tungaloy VBMT110308-PS NS9530 is a high-performance 35-degree rhombic turning insert designed for the final finishing stages where surface integrity is paramount. Featuring the NS9530 Cermet grade, this tool excels in resisting chemical wear and built-up edge, which are the primary causes of dull finishes. The 0.8mm corner radius provides enhanced edge strength and allows for slightly higher feed rates compared to smaller radii, making it a stable choice for continuous finishing. Combined with the -PS (Positive Sharp) chipbreaker, it ensures clean chip evacuation and a polished workpiece appearance on carbon and alloy steels.

Uncoated Cermet Grade

The NS9530 grade utilizes a titanium-based ceramic-metal composite that maintains a sharp cutting edge longer than carbide under high-speed finishing conditions.

-PS Sharp Chipbreaker

Designed with a positive rake angle to minimize cutting resistance, preventing workpiece deformation and ensuring a smooth, vibration-free finish.

Enhanced Edge Strength

The 0.8mm (1/32") radius offers a robust cutting point that resists chipping, allowing for more predictable performance in long finishing cycles.

What Machinists Are Saying

⭐⭐⭐⭐⭐ "Mirror Finish on 4140" - David K., Germany
"Switched to NS9530 for our final pass on alloy steel shafts. The parts come off looking polished. The 0.8mm radius really helps stability."

⭐⭐⭐⭐⭐ "Excellent Edge Toughness" - Hiroshi M., Japan
"Very reliable for finishing. Even on long runs, the dimensional accuracy is consistent. Great cermet quality."

⭐⭐⭐⭐⭐ "Fast Delivery & Original" - Sam P., Australia
"Verified original Tungaloy parts. Arrived in Sydney faster than local suppliers. Highly recommend Beyond Li."

⭐⭐⭐⭐⭐ "Stable Chip Breaking" - Mateo G., Spain
"The -PS breaker works exactly as described. Even at 0.1mm DOC, the chips are manageable and the surface is perfect."

8. Frequently Asked Questions

Q: Can I use NS9530 for stainless steel finishing?

A: Cermet is generally best for carbon and alloy steels. For stainless steel, we recommend the AH725 carbide grade for better edge toughness.

Q: Why choose a 0.8mm radius instead of 0.4mm?

A: 0.8mm provides a stronger cutting edge and allows for faster feed rates, though it generates more radial pressure. It's ideal for stable machines and long finishing passes.

Q: Does this insert require high-pressure coolant?

A: Cermet performs excellently with dry high-speed machining, but standard coolant is also fine for mirror finishing.

Expert Tip: Optimizing Cermet Life

To achieve the **brightest surface gloss**, ensure your cutting speed (Vc) is above 180 m/min. Cermet thrives on speed; the heat helps the material flow smoothly over the **sharp cermet edge**, preventing micro-chipping. **Tungaloy Japan** - Engineering Your Advantage.

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.
