VCMT160404-TM AH6225 — VCMT 160404 turning insert by Tungaloy, PVD‑coated carbide for turning

A VCMT160404‑TM AH6225 ISO‑standard rhombic turning insert engineered for external and internal turning, delivering a sharp but stable cutting edge for medium‑duty machining of stainless steels

• PVD-coated carbide grade AH6225 for stainless steel
• Rhombic VCMT form with 0.4 mm corner radius
• TM chipbreaker for consistent chip control
• 35° approach angle, cylindrical hole with countersink
• 4.76 mm plate thickness for stable clamping

High‑performance grade for stainless steel machining

The VCMT160404‑TM AH6225 is based on a PVD‑coated carbide substrate and the AH6225 grade, which is engineered to balance a sharp cutting edge with the toughness required for stainless steel work. This combination reduces built‑up edge and supports consistent surface quality during medium machining and changing workpiece conditions. In practice, the result is fewer interruptions for rework and a predictable tool life that contributes to efficient cycle times and reduced overall machining cost.

Geometry tailored for accuracy and secure clamping

The rhombic VCMT form and the modest 0.4 mm corner radius deliver an effective compromise between edge strength and the ability to produce fine contours. The insert’s 35° approach angle improves chip flow and cutting forces in many turning set‑ups, while the 4.76 mm thickness and the cylindrical hole with one‑sided countersink (40°–60°) ensure stable seating and repeatable clamping. These geometric details make the insert suitable for both external and internal turning where positional accuracy and reliable clamping are essential.

Controlled chips and stable processes with the TM chipbreaker

A TM chipbreaker provides predictable chip formation across typical stainless‑steel feeds and depths of cut. The breaker is designed to divide chips into manageable segments, which reduces the risk of entanglement and improves component finish. Combined with the PVD surface, the chip control contributes directly to machining stability: fewer tool‑related stoppages, improved operator safety and a smoother downstream handling of swarf.

System compatibility and application guidance

This indexable insert is supplied as an ISO‑standard component and is intended to work within a system comprising a matching external holder or boring bar, backing pad/clamp set and fastening screw. Compatibility depends on the insert form, clearance (7° free angle), tolerance class, fixation and the insert’s size and thickness; therefore the choice of a suitable holder and clamping layout is essential for achieving the grade’s potential. For customers seeking guidance on holder selection or cutting parameters for specific stainless‑steel alloys, Metav Werkzeuge can provide application support and machining recommendations.

FAQ

What materials is this insert suitable for? The VCMT160404‑TM AH6225 is primarily intended for stainless steel machining; the PVD‑coated AH6225 grade is optimised to maintain a sharp, stable edge under variable conditions.

Which chipbreaker is fitted and what benefit does it provide? This insert features a TM chipbreaker, which produces shorter, controllable chips to improve surface quality and reduce swarf issues in turning operations.

How does the insert secure to the holder? The insert uses a cylindrical hole with a one‑sided countersink (40°–60°) and requires a matching clamping system and screw; the 4.76 mm thickness supports secure, repeatable seating.

Is this insert suitable for both external and internal turning? Yes; the geometry and 35° approach angle make it appropriate for many external and internal turning tasks when used with the correct holder and set‑up.

How should holders be selected for optimum performance? Holder selection should match form, free angle, tolerance class, fixation, size and thickness; Metav Werkzeuge can advise on the correct holder and cutting data for specific applications.
