SNMG120404 AH6235 ISO turning insert for turning — Tungaloy

The SNMG120404 AH6235 is an ISO-format turning insert designed for external and internal turning, offering enhanced chip control and improved resistance to edge breakout in stainless steels.

• ISO SNMG format, compatible with standard holders
• PVD-coated AH6235 grade for stainless steel
• 0.4 mm nose radius for fine finishing
• Double-sided design with cylindrical hole for secure clamping

Consistent performance on stainless steels and interrupted cuts

The insert combines a PVD-coated surface with a tough carbide substrate to balance wear resistance and edge stability. This AH6235 grade is formulated for machining stainless steel, particularly where intermittent cutting or risk of chipping exists; the tougher matrix reduces flank and crater wear while the coating helps prevent built-up edge. The result is more consistent surface quality and fewer index changes, which supports higher effective productivity on mixed-production batches.

Straightforward integration into ISO turning systems

The geometry follows the ISO SNMG specification, so compatibility with established external holders and boring bars is determined by form, relief angle, tolerance class, clamping method and plate thickness. The cylindrical hole and 90° table angle ensure reliable clamping and repeatable seating in standard toolposts. This indexable design, being double-sided, doubles the available cutting edges per insert and simplifies tool management in the shop.

Measurable benefits for process reliability and economy

With a 0.4 mm nose radius and a plate thickness of 4.76 mm, the insert supports fine finishing and stable cutting when combined with appropriate feeds and speeds. The combination of grade and chipbreaker yields improved chip control, reducing downtime from clogging and rework. By extending edge life and lowering the frequency of insert changes, the geometry and coating contribute to a shorter cost-per-part and steadier production flow in series and jobbing environments.

FAQ

What materials is this insert best suited for?
The SNMG120404 AH6235 insert is optimised for stainless steel machining, especially where interrupted cuts or higher breakout risk occur; the AH6235 grade balances toughness and wear resistance.

How many usable edges does the insert provide?
As a double-sided SNMG insert, it provides multiple indexable cutting edges per plate, extending run lengths between tool changes and reducing tool costs.

Is the insert compatible with standard ISO SNMG holders?
Yes, the insert follows the SNMG ISO geometry; compatibility depends on holder form, relief angle and clamping method but it is intended for standard external and internal turning holders.

What does the PVD coating deliver in practice?
The PVD coating enhances surface hardness and reduces friction at the cutting edge, improving wear resistance and reducing adhesion tendencies when machining stainless steels.

Can this insert be used for finishing operations?
With a 0.4 mm nose radius and stable edge properties, the plate is well suited for fine finishing passes when appropriate feeds and cutting conditions are chosen.
