DCMT 070204 AH8005 Tungaloy turning insert — ISO rhombic insert for turning

The DCMT070204 AH8005 is an ISO-format indexable turning insert engineered for stable machining of heat-resistant alloys and hard materials in general turning applications.

• PVD-coated cemented carbide AH8005
• ISO rhombic insert DCMT 070204
• Single-sided chipbreaker with hole
• 0.4 mm corner radius and 7° relief

High productivity through robust grade and coating

The PVD-coated cemented carbide grade AH8005 offers enhanced wear resistance for operations on heat-resistant alloys and harder workpiece materials. By combining a hard, thermally stable coating with a substrate engineered for toughness, the insert prolongs cutting life and reduces frequency of index changes. This reliability translates into fewer interruptions on the shop floor and a more predictable tool budget for series production.

Clear compatibility for fast system integration

Designed to the ISO geometry series, the rhomboid insert matches common holder designs when checked for form, relief angle and size tolerances. The standardised designation means the insert fits into any correctly specified ISO holder, provided matching form, thickness and clamping are observed. This simplifies tool planning and minimises setup time when replacing inserts across different machines or fixtures.

Geometry and clamping engineered for predictable chips

The single-sided chipbreaker geometry combined with the rhomboid shape and central hole with a countersink yields consistent chip formation and secure clamping. The centrally countersunk hole (cylindrical hole with one-sided countersink 40°–60°) ensures the insert seats accurately on the clamp and reduces micro-movement under load, which helps maintain surface finish and repeatability in both external and internal turning.

Practical system advice for efficient turning processes

Select the chipbreaker and grade according to workpiece material and machining stability: AH8005 for heat-resistant alloys and hard materials, and a heavier clamp or rigid holder where cutting forces are high. The recommended system consists of the ISO insert, a matching external holder or boring bar, a support shim/clamp set and replacement screws; correct assembly prevents premature wear and supports consistent dimensional results in serial production.

FAQ

What materials is this insert suitable for?
The DCMT070204 AH8005 insert is specified for heat-resistant alloys and harder materials; the AH8005 PVD-coated grade emphasises wear resistance for such workpieces.

How does the insert ensure secure clamping?
The insert’s cylindrical hole with a one-sided countersink and standardised ISO geometry enable firm seating in compatible holders, reducing micro-movement during heavy cuts.

Can this insert be used for internal boring as well as external turning?
Yes; the insert’s rhomboid form, chipbreaker and secure clamping are suitable for both external and internal turning operations when matched with an appropriate boring bar or holder.

What is the corner radius and relief angle of the insert?
The insert features a 0.4 mm corner radius and a 7° relief angle, balancing edge strength and surface finish for general turning tasks.

Which system parts are required to use the insert correctly?
A complete system typically includes the ISO insert, a matching external holder or boring bar, a support shim/clamp set and replacement screws for secure, repeatable mounting.
