DCMT070208 AH725 Tungaloy — ISO turning insert, PVD-coated carbide for Drehen

The DCMT070208 AH725 is an ISO rhombic indexable insert designed for external and internal turning, offering a universal, chip-resistant grade for steel and stainless steel applications.

• PVD-coated carbide AH725 grade
• Rhombic 07 geometry, 7° clearance
• 0.8 mm corner radius for robustness
• Cylindrical hole with single-side countersink

Stable process security for mixed-material production

The insert delivers reliable chip control through its single-sided chipbreaker and the AH725 grade, which is a PVD-coated carbide formulation developed for universal use on steel and stainless steel. This combination reduces the risk of unexpected edge wear and makes the insert particularly suitable where alternating workpiece materials and smaller tool sizes demand consistent results. The design emphasises reduced downtime and predictable tool-change intervals.

Geometry that simplifies set-up and repeatable machining

The rhombic 07 geometry, combined with a 7° clearance angle and a 55° approach angle, ensures precise contact conditions between insert and workpiece. The 0.8 mm corner radius balances strength with the ability to handle moderate finishing cuts, producing consistent surface quality. Because the insert follows ISO form and tolerance conventions, compatibility with standard holders is straightforward, simplifying fixture selection and reducing set-up time.

Coating and grade benefits that extend tool life

The PVD coating on the carbide substrate enhances wear resistance and heat protection at the cutting edge, resulting in longer tool life under varied cutting speeds. The AH725 grade is optimised for stable chip formation and process security, which supports higher productivity and repeatable outcomes in production runs. For operations prioritising economy and dependable finishing, the coated grade offers a strong cost-benefit through fewer index changes.

Practical compatibility and handling for quick changeovers

The insert is supplied in the ISO designation 070208 with a cylindrical hole and single-side countersink (40°–60°), enabling secure clamping and straightforward replacement using common clamping kits and screws. The 2.38 mm plate thickness and standard ISO sizing make it compatible with a wide range of external holders and boring bars; fit depends on form, clearance, tolerance class, clamping method, size and thickness. Clear labelling and standard contours reduce errors during retooling and inventory management.

FAQ

Which materials are suitable for this insert?
The DCMT070208 AH725 Tungaloy insert is designed as a universal, breakout-resistant grade for steel and stainless steel, and performs well when material types vary within a production batch.

What does AH725 mean in practical terms?
AH725 denotes a PVD-coated carbide grade optimised for stable chip formation and process security, offering good wear resistance and reliable edge retention under typical turning conditions.

How does the hole and countersink affect clamping?
The cylindrical hole with a single-side countersink (40°–60°) provides secure, repeatable clamping in standard ISO holders and reduces the risk of insert movement during heavier cuts.

Is this insert suitable for finishing and semi-finishing?
Yes — the 0.8 mm corner radius and rhombic 07 geometry balance edge strength and surface quality, making the insert appropriate for finishing and light to moderate semi-finishing operations.

What should be considered when choosing a holder?
Holder compatibility depends on insert form, clearance, tolerance class, clamping style, size and thickness; select a holder that matches the ISO DCMT070208 geometry and the specified 2.38 mm thickness for optimal fixation.
