DCMT070208 AH6225 Tungaloy turning insert — rhombic ISO 07, PVD-coated carbide for turning

The DCMT070208 AH6225 is an ISO-compliant rhombic indexable insert intended for external and internal turning, optimised for stainless steels and medium cutting conditions.

• PVD-coated carbide AH6225
• Rhombic ISO insert size 07
• 0.8 mm corner radius
• Single-sided chipbreaker with hole

Consistent performance for stainless steel turning

The DCMT070208 AH6225 insert combines a PVD-coated surface with a wear-resistant carbide substrate to deliver a sharp cutting edge that resists chipping under varying conditions. The coating supports temperature management at the cutting zone, which prolongs tool life and reduces process interruptions. For shops seeking dependable cycle times, this geometry delivers repeatable performance in medium-duty operations on stainless steels, where control of work-hardening and edge stability is critical.

Compatibility and system considerations that simplify planning

Designed to the ISO standard, the insert fits conventional external holders and boring bars when matched by form, clearance angle, tolerance class, fixation method, size and thickness. The rhombic shape and a 7° clearance enable straightforward seat and clamping arrangements, while the cylindrical hole with a single-side countersink ensures secure fastening. Specifying ISO parts reduces setup complexity and helps maintain inventory compatibility across multiple toolholders.

Precision geometry for predictable surface finish and tool life

A 0.8 mm corner radius balances edge strength and surface quality: it supports stable cutting at moderate depths of cut while limiting burr formation on stainless alloys. The single-sided chipbreaker promotes controlled chip formation and evacuation, which aids coolant access and reduces the risk of built-up edge. For production environments prioritising consistent surface finish and fewer rework cycles, this insert geometry provides measurable gains in process stability.

Practical benefits for workshop efficiency

The insert’s combination of material and geometry allows longer tool intervals and predictable replacement planning, translating into reduced downtime and lower handling overhead. Selecting the AH6225 grade is particularly advantageous where mixed batches of stainless steel components are machined under variable cutting conditions; the universal character of the grade reduces the need for frequent grade swaps. The result is a more streamlined production flow with fewer tool changes per shift.

FAQ

What materials is this insert suited for?
The DCMT070208 AH6225 insert is formulated for stainless steels, offering a balance of edge sharpness and wear resistance for medium machining.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm corner radius provides greater edge strength than smaller radii while still enabling good surface finish; it helps to reduce edge chipping in interrupted cuts on stainless materials.

Can this insert be used in standard ISO toolholders?
Yes — the rhombic ISO 07 form of the DCMT070208 is compatible with standard ISO toolholders when the holder matches form, clearance angle, size and thickness.

What fastening does the insert require?
The insert is supplied with a cylindrical hole and a one-sided countersink (40°–60°) for secure fixation with standard ISO clamping screws and pads.

Is AH6225 a universal grade?
AH6225 is a universal PVD-coated carbide grade optimised for stainless steels and variable conditions, reducing the need for frequent grade changes during mixed production.
