DCMT DCMT11T312 AH6235 indexable turning insert for Turning by Tungaloy

DCMT11T312 AH6235 Tungaloy indexable insert is a 55° rhomboid insert designed for external and internal turning, optimised for stainless steels and interrupted cutting conditions

• DCMT11T312 - 55° rhombic insert
• PVD-coated cemented carbide AH6235
• 1.2 mm corner radius for robust edges
• Suitable for stainless steel and interrupted cuts

Reliable ISO compatibility reduces set-up time and uncertainty

The insert is manufactured to ISO-standard dimensions, which means compatibility with a broad range of commercially available holders is determined by form, clearance angle, tolerance class, clamping method, size and thickness rather than bespoke geometries. This standardisation supports rapid replacement and fewer toolholder variants on the shop floor, lowering inventory complexity. For production planners this translates into reduced machine downtime, consistent fixturing and predictable changeover times. The relief angle of 7° and the rhomboid geometry ensure a known datum for toolsetting and repeatable positioning in both solid bar turning and boring applications.

Tough PVD-coated grade engineered for stainless steels and tough alloys

The cutting grade AH6235 is a PVD-coated cemented carbide chosen for its toughness and resistance to edge breakdown, especially where interrupted cuts or work-hardening materials like stainless steel are encountered. The coating promotes thermal resistance and adhesion while the substrate provides plastic deformation resistance, which together reduce crater wear and the risk of premature chipping. The combination extends tool life under unstable cutting conditions and contributes to consistent productivity and lower unit costs per component when compared with uncoated or less resilient grades.

Geometry and clamping for secure mounting and improved chip control

The 55° included angle of the rhomboid insert and the 1.2 mm corner radius deliver a practical compromise between edge strength and access to detail work. The insert is supplied with a cylindrical hole and a single-sided countersink (40°–60°) for positive seating and secure clamping in a wide range of ISO-compatible toolholders. A one-sided chipbreaker supports controlled chip formation for turning operations, helping to avoid long, stringy chips in many stainless-steel machining scenarios. The plate thickness of 3.97 mm and size code 11 provide rigid support under moderate depths of cut and are well suited to both external and internal turning tasks where stability is a priority.

Operational benefits and application guidance for shop-floor decision makers

In everyday production the combination of a robust carbide substrate, a PVD barrier coating and an effective chipbreaker results in fewer interruptions from edge failure and more predictable component quality. Typical applications include outer diameter profiling, shoulder turning and light boring where interruptions or built-up edge may occur. For best results, select a holder that matches the insert’s form and tolerance class and adapt cutting parameters to account for the tougher grade — lower cutting speeds and increased feed per revolution are often beneficial at the start when finishing work-hardened stainless steels. The insert’s geometry and mounting design simplify inventory planning and make it a pragmatic choice for job shops and series production alike.

FAQ

What workpieces is this insert best suited for?
The DCMT11T312 AH6235 Tungaloy indexable insert is optimised for machining stainless steel and for operations with interrupted cuts, offering improved edge toughness and reduced breakout risk.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form and specifications; select an ISO-compatible turning holder matching the insert’s 55° rhomboid form, 7° relief and size code 11 to ensure correct seating and clamping.

How does the AH6235 grade affect cutting parameters?
The AH6235 PVD-coated cemented carbide grade provides enhanced toughness; initial cuts typically use moderate speeds and slightly increased feed to avoid built-up edge, then parameters can be optimised for cycle time while monitoring wear.

Is the insert suitable for internal boring as well as external turning?
Yes; the insert’s geometry, thickness and secure hole mounting make it suitable for both external and internal turning, provided the chosen holder permits the required reach and clearance.
