DCMT 070204 AH725 ISO turning insert for turning by Tungaloy

A DCMT070204 AH725 indexable turning insert for ISO-standard applications, developed for external and internal turning where process security and material versatility are required.

PVD-coated AH725 carbide grade for stable edge life
ISO DCMT 070204 geometry for easy holder matching
Suitable for steel and stainless steel machining
0.4 mm corner radius for strengthened cutting edge

Consistent process security from a universal PVD grade

The AH725 grade is a PVD-coated carbide designed for universal use on steel and stainless steel, combining wear resistance with reliable fracture control. For shops processing mixed batches or using smaller tooling, the material and coating reduce the risk of premature edge failure and deliver predictable tool life. Choosing a breakout-resistant grade such as this helps maintain cycle times and reduces unexpected interruptions, making it particularly suitable where repeatable results and process security are priorities.

ISO geometry and precise dimensions simplify integration

The ISO DCMT 070204 form and the specified dimensions — including a 7° clearance angle and 55° lead angle — allow straightforward selection of compatible holders and clamping sets. Compatibility depends on form, clearance, tolerance class, fastening and thickness; the standardised shape ensures interchangeability across ISO tooling systems. The 0.4 mm corner radius provides a compromise between edge strength and surface finish, supporting moderate feeds while limiting the risk of chipping during interrupted cuts.

Practical chip control and system-level benefits

A single-sided chipbreaker and the insert’s hole with a cylindrical bore and one-sided countersink (40°–60°) support secure clamping and effective chip formation in turning operations. The insert forms part of a system comprising an ISO insert, matching external holder or boring bar, shim/clamping kit and replacement screws; this system approach simplifies maintenance and tooling logistics. As a result, productivity improves through predictable tool changes and reduced scrap rates, while machining specialists gain flexibility to adapt insert choice to workpiece material and stability conditions.

FAQ

Which materials is this insert suitable for?
The DCMT070204 AH725 insert by Tungaloy is intended primarily for machining steel and stainless steel and performs well when workpieces vary between these materials.

How does the ISO form affect holder compatibility?
ISO DCMT geometry ensures compatibility with standard external holders and boring bars; correct matching requires checking form, clearance angle, tolerance class, fastening, size and thickness.

What advantages does the 0.4 mm corner radius offer?
A 0.4 mm radius increases edge strength and reduces chipping risk while still allowing reasonable surface finish and feed rates in general turning operations.

When should the AH725 grade be chosen over other grades?
Select the AH725 grade when a universal, breakout-resistant solution is needed for mixed-material batches or when high process security is demanded, particularly with smaller tools.

How does the chipbreaker support machining?
The single-sided chipbreaker aids predictable chip formation and evacuation during turning, helping to maintain stable cutting forces and reduce the likelihood of surface defects.
