TPMT090204 AH6235 TPMT indexable turning insert — PVD‑coated AH6235 grade for turning, 60° triangle, with hole

The TPMT090204 AH6235 indexable insert is an ISO‑standard triangular turning insert designed for external and internal turning, optimised for rostfreier Stahl and applications with a higher risk of chipping.

• PVD‑coated AH6235 carbide grade
• Suited to rostfreier Stahl and interrupted cuts
• ISO triangular insert, 60° geometry
• 0.4 mm nose radius with one‑sided chipbreaker

Higher process reliability in rostfreier Stahl turning

The insert’s PVD‑coated AH6235 grade provides a tougher carbide substrate and a wear‑resistant coating that together improve resistance to chipping during interrupted cuts. This combination results in more consistent cutting performance when machining rostfreier Stahl, where built‑up edge and material stickiness often threaten surface quality. The tougher grade reduces unexpected edge loss and helps to maintain stable chip formation, leading to fewer unscheduled tool changes and improved overall throughput.

Fast integration into ISO tooling systems for predictable set‑up

Designed as part of an ISO indexable insert system, compatibility with a holder is governed by form, clearance angle, tolerance class, clamping method, size and thickness. The triangular 60° geometry and the central hole with a cylindrical bore and single‑side countersink (40°–60°) ensure secure seating and repeatable clamping. This predictable interface reduces set‑up time and increases repeatability across batches, making the insert suitable for production environments that demand quick changeovers and tight tolerance control.

Geometry and chip control that safeguard surface finish

A 0.4 mm nose radius and a one‑sided chipbreaker are balanced to deliver a compromise between edge strength and surface integrity. The 2.38 mm plate thickness supports edge stability under radial loads, while the chipbreaker directs swarf away from the cutting zone, improving evacuation during turning operations. These features help achieve a consistent surface finish with fewer passes and reduced risk of thermal or mechanical damage to the workpiece.

Economic benefits and application guidance

Choosing a tougher, coated grade reduces tool consumption in challenging rostfreier Stahl work and helps avoid scrap and rework. The insert is intended for turning operations where interrupted cuts or unstable chip formation are likely; pairing the insert with an appropriately rated holder, underlay and correct clamping hardware enhances productive machining and protects the cutting edge. For applications outside rostfreier Stahl, confirm material suitability and process parameters to match feeds and speeds to the insert’s strengths.

FAQ

Which materials is this insert best suited for?
The insert is specified for rostfreier Stahl and is particularly effective in interrupted cuts and conditions with elevated chipping risk; the AH6235 PVD coating enhances wear resistance in these applications.

Will the insert fit existing ISO toolholders?
Compatibility depends on form, clearance angle, tolerance class, clamping method, size and thickness; the ISO‑compliant triangular geometry and central hole allow integration with holders designed for TPMT090204‑style inserts.

How should the insert be mounted and secured?
Use a matching outer holder or boring bar with the correct underlay/clamping set and replacement screw; the cylindrical hole with a single‑side countersink ensures firm seating and correct clamp engagement.

What cutting scenarios benefit most from this grade?
Applications involving rostfreier Stahl, interrupted cuts or higher risk of edge breakout will benefit from the tougher AH6235 grade and PVD coating, which together promote stable cutting and longer edge life.
