Tungaloy SCMT09T308-PS AH725 Insert

Reliable Steel & Stainless Turning | -PS Chipbreaker | AH725 PVD Grade

What is the best PVD insert for machining stainless and alloy steel?

The Tungaloy SCMT09T308-PS AH725 is a high-performance square carbide turning insert designed for versatility and edge toughness. Utilizing the advanced AH725 PVD coated grade, this insert provides exceptional resistance to chipping and thermal cracking, making it the primary choice for finishing to medium cutting of steel and stainless steel. The -PS chipbreaker features a sharp, positive rake angle that minimizes cutting forces and enhances surface quality. Made in Japan, this CNC square insert is engineered for precision components where reliability and consistency are non-negotiable.

Tough AH725 PVD Grade

Combines a high-aluminum content (Al-rich) PVD coating with a tough carbide substrate, ensuring excellent resistance to flank wear and built-up edge.

-PS Finishing Breaker

Optimized for light-to-medium depths of cut, this breaker ensures stable chip control even in gummy materials like 304 or 316 stainless.

Premium Surface Integrity

The thin, smooth PVD coating maintains a sharp cutting edge, drastically reducing cutting temperatures and vibration.

⭐⭐⭐⭐⭐ "Smooth Cutting" - L. Tan, Singapore
"Low vibration and very sharp edge. Perfect for our small CNC lathe batch production."

8. FAQ - Professional Support

Q: Is AH725 better than AH120 for steel?

A: Yes. AH725 is a more advanced PVD grade with higher aluminum content, offering superior heat and wear resistance for steel materials.

Q: Can I use this for interrupted cutting?

A: Absolutely. The PVD coating and tough substrate of AH725 are specifically designed to handle the mechanical shock of interrupted cuts better than thick CVD coatings.

Q: What tool holder do I need?

A: Use any standard ISO holder that accepts SCMT 09T3 size (like the SSDCN series).

Expert Tip: Why 0.8mm Radius for PVD?

While 0.4mm is for fine finishing, the 0.8mm radius (Size 308) provides significantly better edge strength. Combined with the AH725 PVD grade, it allows you to push higher feed rates while maintaining a sharp cutting action, making the SCMT09T308-PS the perfect "all-rounder" for any machine shop.

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.
