Quarter‑round profile cutter (R3 mm) — ALPEN‑MAYKESTAG, HSS‑Co, Weldon shank

The quarter‑round profile cutter by ALPEN‑MAYKESTAG for profile milling of construction, case and quenched steels with a concave form and secure Weldon drive

• HSS‑Co for enhanced wear resistance
• Quarter‑round concave profile R3 mm
• 12 mm Weldon shank with drive flat
• Very well suited for steel applications

Longer life through cobalt high‑speed steel and sturdy geometry

The use of HSS‑Co (cobalt high‑speed steel) gives the cutter improved red hardness and edge stability, which translates into longer service life under thermal and mechanical load. The tool’s 4 cutting edges distribute cutting forces evenly, reducing chatter and enabling steady material removal when machining demanding steels. For production workflows this means fewer tool changes and more predictable process windows, improving throughput and reducing downtime.

Accurate concave profiling and dependable clamping for consistent grooves

The cutter’s R3 mm concave profile produces a quarter‑round groove with repeatable geometry; the 4 mm cutting length is optimised for shallow profile work and finishing passes. The 12 mm shank with a drive flat (Weldon) secures the tool in the holder, preventing slip under intermittent or heavy cuts and ensuring concentricity. This combination benefits tasks that demand uniform edge radii and fine surface quality, such as decorative profiling, joint preparation and detailed component finishing.

Application range, workshop benefits and procurement confidence

Designed primarily for milling structural, case‑hardened and quenched steels, the cutter is very well suited for steel and conditionally suitable for stainless steel, non‑ferrous metals and castings. With an overall length of 60 mm and compact geometry, it suits standard milling setups and compact tool magazines. Sourcing through an experienced partner like Metav Werkzeuge brings an assurance of quality: Metav combines a broad range of precision tools with logistics and advisory competence, backed by a large customer base and a European quality filter at its Emmerich location.

FAQ

What materials is this quarter‑round profile cutter best suited for?
The quarter‑round profile cutter (ALPEN‑MAYKESTAG, SKU 4117802006NW) is very well suited for steel, including structural, case and quenched steels; stainless, non‑ferrous metals and castings are only conditionally suitable.

How does the Weldon shank benefit workshop use?
The Weldon shank with drive flat prevents axial and rotational slip in the tool holder, providing secure clamping and consistent groove geometry when using the ALPEN‑MAYKESTAG cutter.

What surface quality can be expected from this cutter?
Thanks to HSS‑Co and the tool geometry with four cutting edges, the cutter delivers stable cutting action and improved edge life, supporting smooth surface finishes on steel profiles.

Is this tool suitable for finishing passes on small radii?
Yes, the R3 mm concave profile and a 4 mm cutting length are intended for precise profiling and finishing of quarter‑round radii and small concave features.

Can this cutter be used in tool holders of standard 12 mm shank machines?
The cutter’s 12 mm shank is compatible with standard 12 mm collets and holders; the Weldon drive flat further secures the tool for medium to demanding milling operations.
