CPMT080204 AH6225 Tungaloy indexable insert — Turning, ISO CPMT geometry

A CPMT080204 AH6225 indexable turning insert engineered for external and internal turning of stainless steel, featuring a rhombic form, 11° relief and a 0.4 mm nose radius for versatile medium machining.

• PVD-coated AH6225 carbide grade
• ISO CPMT geometry for holder compatibility
• 0.4 mm nose radius for versatile finishing
• Single-sided chipbreaker for stainless steel

Consistent, economical performance in stainless steel turning

The PVD‑coated AH6225 grade combines a sharp cutting edge with edge stability suited to variable workshop conditions, delivering a balanced mix of wear resistance and toughness. This makes the insert especially effective when machining stainless steel in medium cutting regimes, where repeated tool life and surface quality are priorities. The coated cemented carbide substrate reduces flank wear and stabilises cutting forces, which supports longer uninterrupted cycles and more predictable tool change intervals, improving process efficiency on production and jobbing lathes.

Secure clamping and ISO compatibility for predictable set‑ups

The ISO CPMT080204 geometry ensures compatibility with standard CPMT holders; the plate form, relief angle and tolerance class are matched to the holder family to provide repeatable clamping and concentricity. The insert features a central hole with a cylindrical bore and a single‑sided countersink (40°–60°), enabling robust fixation with the usual screw-and-seat systems. With a plate thickness of 2.38 mm and a rhombic shape, the component offers stable seating, reduced vibration and consistent chip control—factors that directly affect surface finish and tool life.

Machining benefits and practical application advice

The single‑sided chipbreaker designed for this grade aids chip formation when turning ferritic and austenitic stainless steels, reducing built‑up edge and improving evacuation. The modest 0.4 mm nose radius allows better control of surface finish without excessive cutting forces, while the 11° relief minimises rubbing on the flank. For best results, choose feeds and speeds matched to the grade’s medium‑duty range and pair the insert with a rigid toolholder and stable workpiece clamping; this combination yields consistent dimensional accuracy and reduces the risk of chatter. The insert supports both external and internal turning operations when matched with the appropriate holder and set‑up.

FAQ

What materials is this insert designed for?
The CPMT080204 AH6225 insert is specified as a universal grade for stainless steel, optimised for medium machining with a balance of edge sharpness and stability.

Which toolholders fit this insert?
The ISO CPMT080204 geometry matches standard CPMT turning holders and boring bars; compatibility depends on holder form, relief, tolerance class, fastening and plate size.

What is the purpose of the single‑sided chipbreaker?
The single‑sided chipbreaker on this Tungaloy insert promotes controlled chip formation when turning stainless steels, helping to avoid built‑up edge and easing chip evacuation.

How does the 0.4 mm nose radius affect surface finish?
A 0.4 mm nose radius gives a compromise between surface quality and cutting force; it enables improved finishing without excessive tool load when using appropriate feeds.

Is the insert supplied with screws or a clamping set?
The CPMT080204 AH6225 insert is supplied as the indexable plate itself; holders, underlay/locking sets and replacement screws form the system and should be procured separately.
