6mm Cylindrical End Mill HSS-Co8 4 Flute Short 4mm Cut, DIN 844 Weldon Shank - TECWERK

The combination of a high‑cobalt HSS‑Co8 grade, DIN 844 Type N geometry and a short, rigid design provides reliable metal‑removal performance and reduced chatter for demanding workshop tasks; order via Metav Werkzeuge or consult the technical team for application advice.

TECWERK HSS‑Co8 DIN 844 Type N 6 mm 4‑Flute Short End Mill, Weldon Shank

The TECWERK HSS‑Co8 DIN 844 Type N 6 mm end mill is a short, four‑flute cylindrical shank cutter designed for precision milling of steels and cast iron in conventional and CNC setups

• High‑cobalt HSS‑Co8 core for durability
• DIN 844 Type N geometry, 4 flutes
• Weldon shank for secure clamping
• Short design with 19 mm effective length

Precise cutting performance for medium‑strength metals

The short four‑flute design with centre‑cut geometry and HSS‑Co8 material enables controlled entry into material and consistent chip evacuation. The tool follows the DIN 844 specification, which standardises flute geometry and tolerances to ensure repeatable results in production environments. With a nominal diameter of 6 mm and 4 cutting edges, the cutter balances material removal rate and surface finish, while the right‑hand cut promotes predictable tool behaviour in standard machining directions. For uncoated variants the tool is suited to workpieces up to approximately 800 N/mm², and performance can be extended to around 1000 N/mm² when a suitable coating is applied.

Short overall length for stiff clamping and reduced vibration

A short design with an effective length of 19 mm and an overall length of 57 mm reduces overhang and therefore deflection during milling operations. The Weldon shank and cylindrical body with a drive flat provide secure clamping in holders that accept Weldon‑style shanks, improving repeatability and reducing the risk of slippage under load. The cutting length of 4 mm and the specified relief length ensure that the cutting zone is focused and rigidity is maximised, which is particularly advantageous when machining narrow shoulders, slots or finishing passes where dimensional control and surface quality matter.

Application spectrum and workshop suitability

This tool is optimised for machining steel and cast iron, where it is rated as very good for tool life and performance; suitability for non‑ferrous metals and stainless steel (INOX) is indicated as conditional and depends on cutting parameters and workpiece condition. Typical applications include slotting, side milling and light profiling in metalworking shops, tool rooms and small‑batch CNC production. The combination of a high‑cobalt substrate and DIN‑compliant geometry means the cutter is a practical choice for shops seeking a durable, economical end mill for medium‑strength materials and occasional tougher tasks when paired with an appropriate coating.

FAQ

What materials is this end mill best suited for?
The TECWERK HSS‑Co8 DIN 844 Type N 6 mm end mill is rated very good for steel and cast iron; performance on non‑ferrous metals and stainless steel is conditional and depends on cutting data.

Can the tool be used in CNC machines as well as manual mills?
Yes, the short design and Weldon shank of this TECWERK cutter make it suitable for both CNC and conventional milling setups where rigid clamping is possible.

What clamping interface is required for secure use?
A toolholder accepting a Weldon‑style shank with a flat for positive drive is required to ensure secure clamping and repeatable results with this cutter.

How deep can this cutter mill in a single pass?
The specified cutting length is 4 mm, which defines the maximum practical axial depth for a full immersion cut without exceeding the intended effective cutting zone.

Does the cutter handle hardened steel?
This tool is intended for materials up to roughly 800 N/mm² when uncoated; harder or pre‑hardened steels will require specialised tooling rather than this HSS‑Co8 DIN 844 Type N cutter.
