SNMG 190612 AH6225 Tungaloy indexable turning insert — PVD‑coated carbide, 90°

The SNMG190612 AH6225 Tungaloy insert is an ISO‑standard indexable insert designed for general turning, optimised for rostfreier Stahl and mixed‑condition machining.

• SNMG190612 geometry for general turning
• PVD‑coated AH6225 carbide for stainless steel
• Double‑sided chipbreaker for stable chip control
• Square 19 mm, 6.35 mm thick, 1.2 mm radius

Consistent performance for rostfreier Stahl turning

The AH6225 grade is a PVD‑coated carbide engineered as a universal solution for stainless steel machining. Its formulation balances a sharp cutting edge with edge stability under fluctuating cut conditions, reducing built‑up edge and promoting a consistent surface finish. For medium cutting depths and variable feeds, this combination lowers the risk of premature flank wear and supports longer intervals between indexings, which in turn reduces downtime and tool handling.

Secure clamping and geometry that reduces vibration

The insert’s square form and 6.35 mm plate thickness provide the rigidity required for stable turning operations; the cylindrical hole ensures positive seating and repeatable clamping when paired with the correct holder and clamping set. The specified 0° clearance and 90° included angle give predictable engagement geometry that helps maintain dimensional accuracy and reduce chatter in many lathe setups. The double‑sided chipbreaker supplies dependable chip control across a range of feeds, improving cycle reliability.

Economical indexing and system compatibility

As an ISO‑standard indexable plate, the SNMG190612 fits into common clamping systems provided the holder matches in form, tolerance class, fastening style, size and thickness. The 1.2 mm corner radius delivers a robust edge suited to moderate turning, offering a good compromise between edge strength and achievable surface quality. Selecting the correct chipbreaker and following the grade’s intended use for rostfreier Stahl will maximise tool life and reduce total machining cost per part; consult the insert’s system requirements when planning holder and screw choices.

FAQ

Which materials is this insert optimised for?
The AH6225 grade of the SNMG190612 insert is optimised for rostfreier Stahl (stainless steel); selection of chipbreaker and machining parameters determines suitability for other alloys.

How is compatibility with a holder determined?
Compatibility depends on the insert’s shape, clearance angle, tolerance class, fastening type, size and thickness; the SNMG190612 must be matched to a holder designed for ISO‑standard square inserts.

How is the insert mounted and clamped?
The plate uses a cylindrical centre hole and is secured with the appropriate clamping set and screw in a matching external holder or toolpost system.

Does the grade provide reliable edge life under varying conditions?
The PVD‑coated AH6225 grade is formulated to provide a sharp yet stable edge in medium machining and changing conditions, offering dependable performance and reduced risk of edge chipping.

Can the insert be indexed for multiple cutting positions?
The square, double‑sided design allows economical indexing within compatible holders; the exact number of usable positions depends on the holder and mounting method.
