Quarter‑radius profile cutter DIN 6518B Type N — R 6 mm, D 20 mm (HSS‑Co, Weldon) by ALPEN‑MAYKESTAG

The Quarter‑radius profile cutter DIN 6518B Type N is a compact profile cutter designed for precise concave milling of construction, tool and quenched‑and‑tempered steels in production and workshop environments.

• HSS‑Co for increased wear resistance
• Concave quarter‑radius profile R6 mm
• Weldon shank Ø16 mm with drive flat
• Very good suitability for steel

Durable cutting performance for demanding steels

The cutter combines a high‑cobalt HSS‑Co composition with the DIN‑specified Type N geometry to deliver enhanced hot hardness and improved wear resistance under continuous machining. This material choice reduces flank wear and maintains the R6 mm profile over longer production runs, resulting in longer tool life and fewer tool changes. Right‑hand cutting direction and the concave form support stable chip formation when working with hardened or tempered steels, contributing to consistent dimensional accuracy and reduced scrap rates.

Consistent profile accuracy and reliable clamping

Standardised geometry according to DIN 6518B guarantees interchangeability and predictable edge forms for profile work. The concave quarter‑radius profile produces clean, repeatable contours and grooves with minimal secondary finishing. The Weldon shank design, paired with a 16 mm shank diameter and an 8 mm neck, offers rigid support in the tool holder and prevents slippage during heavier cuts. This mechanical stability translates into improved surface finish and predictable process outcomes in batch production.

Efficient application across workshop materials

The tool is optimised for use on steel (very good suitability) and is conditionally suitable for non‑ferrous metals, stainless steel and cast iron, allowing flexible deployment across common workshop tasks. The Type N profile is particularly suited to profile milling, form generation and edge rounding in component manufacture. By focusing on process reliability and reduced downtime, the cutter supports operational efficiency and a lower total cost of ownership for routine profile machining tasks.
