End mill DIN 844 Type N, 18 mm, HSS‑Co8 with Weldon shank — TECWERK

An end mill DIN 844 Type N 18 mm HSS‑Co8, designed for long‑reach milling and centre‑cutting operations with a Weldon shank for positive drive

• HSS‑Co8 high-speed steel construction
• DIN 844 Type N long‑reach design
• Four‑flute centre‑cutting geometry
• Weldon shank with drive flat for secure clamping

Robust tool steel for consistent machining performance

The cutter combines a HSS‑Co8 alloy with the standardised geometry of DIN 844 Type N, delivering a balance of toughness and dimensional reliability. This material choice supports machining of medium‑to‑high strength workpieces: the tool is specified for uncoated applications up to approx. 800 N/mm² tensile strength and, when coated, up to 1,200 N/mm², providing a predictable basis for process planning. The long‑reach profile reduces the need for workpiece repositioning, improving workflow efficiency in production environments.

Secure clamping and versatile cutting action

Equipped with a Weldon shank and a cylindrical mounting with drive flat, the cutter ensures a positive mechanical connection to the holder for high feed forces and reduced slippage. The four‑flute layout supports a favourable balance between material removal rate and surface finish, while the centre‑cutting geometry permits limited plunge operations, increasing process flexibility. These design features translate into stable performance during deep slotting and profile milling tasks common on CNC machining centres.

Clear suitability across materials and applications

Material suitability is specified for a range of common workshop metals: very good suitability for steel and cast iron, and conditional suitability for non‑ferrous metals and stainless steels. The tool is therefore particularly well suited to slotting, profiling and finishing operations in general manufacturing and repair shops where a robust, long‑reach cutter is required. The defined material limits and DIN compliance facilitate tool selection for series production as well as one‑off jobs.

Practical integration and handling benefits

The standardised shank and right‑hand cutting direction make the cutter straightforward to integrate into existing toolsets. The Weldon drive flat simplifies change‑over and reduces setup time, supporting predictable clamping repeatability. Clear conformity to DIN 844 Type N means toolholders and tool management systems can readily accommodate the item, helping to maintain process continuity across shifts and machines.

FAQ

Is this end mill suitable for plunge milling?
The tool features a centre‑cutting geometry that permits limited plunge milling; the end mill DIN 844 Type N 18 mm HSS‑Co8 is designed to handle vertical engagement within its specified cutting parameters.

Which materials are best processed with this cutter?
The cutter is optimised for steel and cast iron with very good suitability; non‑ferrous metals and stainless steel are conditionally suitable depending on cutting data and coating choices.

Can the Weldon shank be held in standard toolholders?
Yes, the cylindrical shank with drive flat (Weldon) is compatible with standard Weldon‑style holders and provides a secure mechanical drive for high feed forces.

What advantages does the HSS‑Co8 material offer for this tool?
The HSS‑Co8 composition provides enhanced red hardness and resistance to softening under elevated cutting temperatures, supporting stable machining in demanding operations.

Is the cutter compliant with industry standards for tool dimensions?
The design conforms to DIN 844 Type N, offering standardised dimensions for straightforward integration into existing tooling inventories.
