CNMG190616 AH6225 ISO turning insert for turning — Tungaloy

CNMG190616 AH6225 is an ISO-standard indexable turning insert designed for general turning applications, providing a balanced mix of sharpness and edge stability for machining stainless steels.

• ISO-compatible rhombic insert
• PVD-coated carbide grade AH6225
• 80° lead angle for stable cutting
• Double-sided with cylindrical hole

Consistent compatibility with ISO toolholders improves uptime

The ISO-standard geometry ensures straightforward interchangeability with a wide range of ISO toolholders and boring bars. Compatibility is governed by form, clearance angle, tolerance class, fastening and dimensional match; keeping these parameters aligned reduces setup time and prevents clamping errors. The rhombic form with an 80° lead angle gives reliable support in external and internal turning operations, while the cylindrical hole and standardised attachment method permit secure clamping and fast insert replacement, contributing to uninterrupted production flow.

Reliable grade for rostfreie Stähle and mixed conditions

The AH6225 grade is a PVD‑coated carbide developed as a universal choice for rostfreie Stähle, delivering a sharp yet stable cutting edge under medium cutting conditions and variable workpiece behaviour. This balance lessens the tendency for rapid flank wear and edge chipping often encountered with harder or more adhesive stainless grades. Selecting the appropriate chipbreaker and matching the grade to workpiece stability will enhance surface finish consistency and extend the effective life of the cutting edge.

Geometry that supports productivity and machining quality

Key geometric elements — edge radius 1.6 mm, thickness 6.35 mm and rhombic shape — contribute to rigidity and heat distribution at the cutting zone. A larger corner radius improves tool strength and surface finish when cutting with sufficient depth of cut, while the standardized thickness assists in correct seat support within the holder, avoiding micro‑movement that shortens insert life. The double‑sided design doubles the number of available cutting edges, reducing inventory cost per usable edge and improving overall economy.

Practical system considerations for workshop integration

An efficient system setup comprises the ISO insert, a suitable outer holder or boring bar, a matching shim/clamp set and replacement screws. The insert’s 0° clearance angle and ISO form mean that the correct holder profile must be chosen to match the insert’s seat and tolerance class for optimal contact and force transmission. For selection advice, choose the chipbreaker and grade according to workpiece material, machining type and machine‑tool rigidity; this approach ensures process reliability and repeatable results across batches.

FAQ

Is this insert suitable for stainless steels?
The CNMG190616 AH6225 insert is specified as a universal grade for rostfreie Stähle, offering a combination of sharpness and edge stability suited to medium turning operations.

Which insert geometry benefits heavy interrupted cuts?
A larger corner radius and the rhombic CNMG form provide better edge support and distribute cutting forces, which helps during less stable or interrupted machining conditions.

Can the insert be used on both external and internal turning operations?
Yes, the ISO CNMG form and the 80° lead angle make the insert adaptable for both external and internal turning when paired with the appropriate holder.

What does the cylindrical hole provide?
The cylindrical hole enables secure clamping and precise seating in compatible ISO holders, improving repeatability and reducing the likelihood of insert movement under load.
