SNMG 190612 AH6235 indexable turning insert by Tungaloy — PVD-coated carbide, 90° square geometry

SNMG 190612 AH6235 is an ISO-standard indexable turning insert designed for external and internal turning, optimised for rostfreier Stahl and interrupted cutting conditions.

• PVD-coated AH6235 grade
• Designed for rostfreier Stahl and interrupted cuts
• Square SNMG form with 90° approach angle
• Double-sided chipbreaker, cylindrical hole

Engineered for secure cutting in demanding turning operations

The PVD-coated AH6235 carbide composition provides a tougher substrate tailored for machining rostfreier Stahl and for operations with elevated risk of insert breakout. This formulation produces more stable cutting edges under shock loading and interrupted cuts, which translates to fewer edge failures and longer cumulative cutting time. Compatibility with a compatible holder depends on insert form, 0° relief angle, tolerance class, clamping method, size and thickness, so selecting the correct clamping kit and shim is essential for achieving the promised stability.

Predictable productivity through robust geometry and coating

A square insert with a 90° approach angle and a 1.2 mm corner radius offers a balance between strength and versatility, suitable for shoulder turning and general profiling where a sturdy edge is required. The double-sided chipbreaker design and the insert’s cylindrical hole enable secure clamping and multiple index positions, extending practical service life and lowering per-edge cost. The PVD coating reduces flank wear and helps maintain consistent surface finish, supporting higher uptime and improved batch-to-batch repeatability.

Practical selection and workshop integration guidance

Choose chipbreaker style and grade based on workpiece material, machining type and machine/tooling rigidity; the tougher AH6235 grade is recommended for rostfreier Stahl and unstable cutting conditions. The full system comprises an ISO insert, a matching external holder or boring bar, a support shim/clamping set and replacement screws — keeping spare fastening hardware in stock simplifies maintenance. For quieter, more efficient runs, pair the insert with a holder that matches the SNMG form, 19 mm nominal plate size and 6.35 mm thickness to ensure correct clamping and repeatable process security.

FAQ

What materials is this insert best suited for?
The AH6235 grade is formulated for cutting rostfreier Stahl and performs well in conditions with interrupted cuts; the SNMG 190612 geometry supports robust engagement.

What is the corner radius and why does it matter?
The insert has a 1.2 mm corner radius, which provides enhanced edge strength for shoulder turns and heavier feeds while maintaining acceptable surface finish levels for many turning tasks.

Is this an indexable, double-sided insert?
Yes — the SNMG 190612 insert features a double-sided chipbreaker and a cylindrical hole for secure clamping and multiple index positions to extend usable life.

How does the PVD coating affect tool life?
The PVD coating on the AH6235 carbide improves wear resistance and reduces flank wear, helping to preserve cutting-edge geometry and deliver consistent results across production batches.

What factors determine holder compatibility?
Compatibility is governed by insert form, relief angle, tolerance class, clamping method, size and thickness; ensure the external holder or boring bar matches the SNMG form and the 6.35 mm thickness for correct fitment.
