Quarter‑circle profile cutter DIN 6518B Type N, R 1 mm, Ø 8 mm — HSS‑Co, Weldon shank

A Quarter‑circle profile cutter DIN 6518B Type N designed for accurate concave profiling in construction, case‑hardened and quenched steels, featuring a Weldon cylindrical shank for secure clamping

• HSS‑Co construction for demanding steels
• DIN 6518B, Type N geometry for precision
• Weldon shank Ø10 mm with drive flat
• Concave quarter‑radius R1 mm profile

High‑performance geometry for predictable results

The cutter is built in HSS‑Co, which combines hardness and toughness to maintain cutting edge integrity under intermittent and heavy loading. Its DIN 6518B Type N geometry gives a defined concave profile with R1 mm, enabling precise quarter‑radius contours without secondary profiling operations. With 4 cutting edges, the tool distributes cutting forces evenly, which helps to reduce chatter and extend tool life — beneficial in batch production where consistency reduces rework and downtime. The result is a reliable tool for profile milling where dimensional repeatability is essential.

Improved surface finish and reduced processing steps

A dedicated profile tool of this form produces the required contour and a controlled surface quality in a single pass. The combination of the concave R1 mm contour and the Type N form minimises the need for subsequent finishing, saving time on each part. The cutter is right‑hand cutting, ensuring conventional feed patterns and machine set‑up. For workshops moving from general‑purpose cutters to profile tools, this cutter offers a clear efficiency gain through fewer tool changes and predictable part output.

Secure clamping and practical handling

The Weldon shank Ø10 mm with drive flat offers a secure mechanical grip in standard toolholders and shrink or collet fixtures designed for Weldon profiles. The solid shank design supports stable machining even during interrupted cuts and gives straightforward handling on both conventional and CNC milling centres. The Ø 8 mm cutting diameter combined with an overall length of 60 mm and a cutting length of 4 mm provides a compact footprint while allowing adequate reach for many profiling tasks.

Recommended applications and material suitability

This cutter is intended primarily for steel and is marked as very well suited for steel, including construction, case‑hardened and quenched variants. It is conditionally suitable for non‑ferrous metals, stainless steel and cast iron, which means testing on the specific alloy and machining conditions is advised before series use. Typical applications include radius profiling on components, mould and die preparatory work for edges, and finishing operations where a defined concave section is required. Use appropriate coolant and conservative feeds when processing hard or heat‑treated materials to preserve edge life and surface integrity.

FAQ

What materials is this quarter‑circle cutter best suited for?
The quarter‑circle profile cutter in HSS‑Co is very well suited for steel, including construction and heat‑treated steels; it is conditionally suitable for non‑ferrous metals, stainless steel and cast iron depending on the alloy and machining parameters.

Which shank size and clamping type are required?
The cutter uses a Weldon shank Ø10 mm with drive flat; compatible Weldon toolholders or fixtures with a matching clamping capacity are recommended for secure mounting.

Is the tool coated?
No coating was specified for this item; the tool is supplied in HSS‑Co substrate without additional surface coating.

What profile does the tool create and how precise is it?
The tool produces a concave quarter‑circle profile with R1 mm radius and is built to DIN 6518B Type N geometry, providing a defined contour suitable for precision profile milling.

Can this cutter be used on CNC machines and conventional mills?
Yes; the cutter is suitable for use on both CNC milling centres and conventional mills provided the machine and holder support a Weldon shank Ø10 mm and appropriate feeds and coolant are applied.
