End mill DIN 844 Type N, 5 mm (HSS‑Co8, 4‑flute, long, Weldon shank) – TECWERK

The End mill DIN 844 Type N is a long, four‑flute high‑speed steel cutter with centre‑cut geometry, designed for general milling of steel and cast iron in medium‑duty industrial applications.

*HSS‑Co8 high-speed steel for improved tool life
*DIN 844 Type N – long shank for deep milling
*Four-flute, centre-cut geometry for accurate results
*Weldon shank (6 mm) with drive flat for secure clamping

Robust high-speed steel construction for consistent machining

Made from HSS‑Co8, this long end mill delivers a balance of toughness and hot‑hardness that supports stable cutting edges under fluctuating loads. The four‑flute layout increases cross‑sectional stiffness, while the centre‑cut design permits controlled plunge operations where necessary; this combination reduces chatter and improves surface finish on interrupted cuts. According to the tool specification, machining of materials up to ~800 N/mm² is viable with the uncoated tool, with potential extension to ~1200 N/mm² if a suitable coating is applied, which offers measurable flexibility across different production tasks.

Precision dimensions and secure clamping for repeatable results

Compact yet rigid dimensions contribute to predictable tool behaviour: 5 mm cutting diameter, 6 mm shank diameter and an overall length of 68 mm with an effective cutting length of 24 mm. The Weldon shank with drive flat ensures a positive mechanical grip in collets and end mill holders, reducing the risk of slippage during heavy engagement. This configuration supports deep pocketing and slotting in small diameters while maintaining tool stability, so set‑ups run with fewer interruptions and consistent tolerances.

Application range and practical machining guidance

The cutter shows very good suitability for steel and cast iron, with conditional applicability for non‑ferrous metals and stainless steels; right‑hand cutting is standard for efficient chip evacuation. Its long design is particularly useful for components requiring access into recessed features or stepped profiles. For stainless and tougher alloys, reduced feed or optimised coolant use is recommended to manage built‑up edge and heat; when climb‑milling and appropriate axial depth values are chosen, the tool performs efficiently in repetitive production cycles.

FAQ

What materials is this end mill suitable for?
The End mill DIN 844 Type N is designed for very good performance on steel and cast iron, with conditional suitability for non‑ferrous metals and stainless steels according to the tool specification.

Can this cutter be used for plunge milling?
Yes, the centre‑cut geometry allows controlled plunge milling when required, making the cutter versatile for operations beyond conventional slotting.

What are the key dimensions for toolholder selection?
Select toolholders for a 6 mm Weldon shank and account for the 68 mm overall length and 24 mm effective cutting length when setting up fixtures.

How many cutting edges does the cutter have and what is the impact?
The cutter features four cutting edges; the four‑flute arrangement increases stiffness and improves surface finish on continuous cuts, while helping chip control in many materials.

Is this the correct cutter for deep pocketing in small diameters?
The long version of this DIN 844 Type N cutter is specifically suited to reach recessed features and perform deep pocketing in limited diameters, provided feeds and speeds are adapted to the workpiece material.
