20mm Quarter Radius Concave Profile Cutter R6mm 4-Flute HSS-Co Weldon Shank, Right-Hand - ALPEN-MAYKESTAG GmbH

Benefit from a robust combination of HSS‑Co construction, a R 6 mm concave profile and a secure 16 mm Weldon shank for reliable, repeatable profiling; order the cutter directly via Metav Werkzeuge or consult the specialists for application advice.

Viertelkreisprofilfräser DIN 6518B Typ N R.6mm D.20mm HSS-Co Weldon – quarter‑round profile cutter with concave form and Weldon shank

Viertelkreisprofilfräser DIN 6518B Typ N R.6mm D.20mm HSS-Co Weldon is a quarter‑round profile cutter designed for precision profiling in construction, quenched and tempered steels and general workshop milling tasks.

• HSS‑Co for high durability
• R 6 mm quarter‑round concave profile
• Ø 20 mm cutter diameter
• 16 mm Weldon shank with drive flat
• Right‑hand cutting for conventional milling

Precision profile and lasting performance

When a consistent quarter‑round profile is required, the HSS‑Co composition delivers a balance of toughness and wear resistance that supports continuous use in workshop environments. The R 6 mm concave form produces a defined decorative or functional profile with minimal surface uplift, while the presence of 4 cutting edges promotes even material removal. Because the geometry complies with DIN 6518 B and Type N specifications, the cutter is suitable where reproducible contours and tool life are decisive factors; the result is a lower rework rate and higher process reliability.

Efficient machining for steel and versatility across materials

This profile cutter is very well suited for steel, including construction and tempered variants, thanks to the cobalt‑alloyed high‑speed steel substrate. The Ø 20 mm diameter and a cutting length of 4 mm mean shallow, controlled runs are favoured—ideal for creating neat edge radii and profiles without excessive cutting forces. Use with non‑ferrous metals, stainless steel and cast iron is possible but should be treated as conditional: machining parameters and feed rates must be adapted to material ductility and workpiece hardness to avoid premature wear.

Secure mounting and reliable power transmission

A 16 mm Weldon shank with drive flat ensures positive drive and reduced slippage in toolholders, enabling stable torque transfer on machine spindles and milling arbors. The tool’s right‑hand cutting orientation suits standard rotation and feed directions, simplifying planning for typical CNC and manual milling setups. The combination of a rigid shank and the compact overall length of 67 mm keeps deflection low, so tighter tolerances can be maintained with confidence on small to medium‑sized components.

FAQ

What materials is this profile cutter suitable for?
The Viertelkreisprofilfräser DIN 6518B Typ N R.6mm D.20mm HSS‑Co Weldon (SKU 4117802012NW) is very well suited for construction and quenched/tempered steels; use with non‑ferrous metals, stainless steel and cast iron is conditional and requires adapted cutting data.

What shank and clamping system are required?
A 16 mm Weldon shank with a drive flat is provided, so a matching Weldon holder or chuck that secures the flat is recommended for stable power transmission.

Which profile and finish can be expected from the cutter?
The tool produces a R 6 mm quarter‑round concave profile with smooth surface finish when used with appropriate feeds and speeds for the workpiece material.

How deep can a single pass be with this cutter?
The specified cutting length is 4 mm; this limits the effective engagement per pass and supports accurate, controlled profiling rather than deep roughing operations.

Is the cutter compliant with industry standards?
Yes, the geometry follows DIN 6518 B and the tool is classified as Type N, ensuring compatibility with standardised toolholders and machining strategies.
