DCMT 070204 AH6225 Tungaloy turning insert — ISO turning insert for Drehen

A DCMT070204 AH6225 turning insert for external and internal turning that delivers a sharp, stable cutting edge optimised for rostfreie Stähle in changing machining conditions.

• PVD-coated carbide grade AH6225
• Optimised for stainless steel machining
• 55° rhombic geometry for versatile turning
• Cylindrical hole with 40°–60° countersink

Proven performance for stainless steel turning

The insert is supplied in grade AH6225, a PVD-coated carbide composition developed for reliable performance when machining stainless steel. The coating improves wear resistance and thermal stability, which means the cutting edge remains effective over longer engagement times; this reduces tool changes and supports uninterrupted production. With an edge radius of 0.4 mm, the geometry balances finish quality and edge strength, making it suitable for medium cutting depths where a compromise between surface integrity and tool life is required. The result is a dependable insert that maintains consistent dimensional results under variable conditions.

Secure geometry and straightforward mounting for stable cuts

A rhombic 55° geometry provides versatility across both external and internal turning tasks, allowing effective approach angles while preserving flank support. The insert features a cylindrical hole with a one-sided countersink (40°–60°), which ensures secure clamping and repeatable seating in compatible holders; compatibility is determined by holder form, relief angle, tolerance class, fastening, size and thickness. The plate thickness of 2.38 mm gives robust support for the cutting edge, and the ISO designation simplifies selection for standard toolholders. These design elements combine to reduce vibration and improve cutting stability, leading to better surface finishes and predictable tool life.

Practical application guidance and productivity benefits

The single-sided chipbreaker and the combination of grade and geometry are intended to assist with chip control and process reliability during turning operations. For external and internal turning, select the chipbreaker and cutting parameters that match workpiece stability and material condition; this indexable insert is a solid choice where consistent performance with rostfreie Stähle is required. Where process optimisation is sought, matching the insert to an appropriate holder and adapting feed and speed will yield measurable productivity gains. If further cutting data or specific advice is required, Metav Werkzeuge provides application support by e‑mail and phone to help integrate the insert into the production process.

FAQ

Is this insert suitable for internal turning operations?
The DCMT070204 AH6225 insert is designed for both external and internal turning; its 55° rhombic geometry and reliable clamping hole allow use in appropriate internal toolholders when stability and tool access are sufficient.

Which materials does the AH6225 grade work best with?
The AH6225 PVD-coated carbide grade is optimised for rostfreie Stähle and performs well under medium-duty conditions where a sharp yet stable cutting edge is required.

How does the hole and countersink style affect mounting?
The cylindrical hole with a one-sided countersink (40°–60°) ensures secure and repeatable seating in compatible holders; correct matching of holder form and tolerance class is essential for optimal clamping.

What cutting edge radius is recommended for finishes and strength?
This indexable insert features a 0.4 mm corner radius, which offers a practical balance between surface finish capability and edge robustness for general-purpose turning tasks.

Can the DCMT070204 AH6225 be used interchangeably with other ISO inserts?
The insert follows ISO dimensions, but interchangeability depends on holder relief angle, fastening method and plate thickness; ensure holder compatibility before substitution.
