End mill DIN 844 Type NR D 8 mm – HSS‑Co5, TiCN, Weldon shank (TECWERK)

The End mill DIN 844 Type NR D 8 mm is a short, multi‑flute solid tool designed for general milling and plunge operations in a workshop environment.

• End mill DIN 844 Type NR, 8 mm diameter
• HSS‑Co5 with TiCN coating
• Weldon shank with drive flat for secure clamping
• Centre‑cut design for controlled plunge milling

High‑performance substrate and coating for consistent productivity

The combination of HSS‑Co5 substrate and TiCN coating delivers a balance between toughness and wear resistance that suits short, intermittent cuts. The coated variant extends the allowable material strength to 1000 N/mm², while the uncoated tool is rated to 800 N/mm², which makes the tool appropriate for many common industrial steels and cast iron. The multi‑flute, short profile reduces deflection under load and improves stability in slotting and pocketing tasks; the centre‑cut geometry permits reliable plunge cuts without pre‑drilling. These characteristics translate into fewer tool changes and a smoother production flow when compared with longer or less robust cutters.

Practical design elements that speed set‑up and protect the tool

Engineered to DIN 844 specifications, the tool features a Weldon shank with drive flat, ensuring positive torque transfer in standard toolholders and easy axial location in automated fixtures. The 45° chamfer protects the cutting edges during engagement and reduces chipping in the entry zone, while the relief‑ground helix profile promotes consistent chip formation and evacuation. Right‑hand cutting and the short flute length minimise vibration in compact setups. Together, these design details reduce setup time and support repeatable quality in serial production.

Suitable applications and material guidance for workshop use

This short, robust cutter is very well suited to machining steel and cast iron in light to moderate machining tasks. Non‑ferrous metals, stainless steels and special alloys are usable with caution and process optimisation; consider the coated version for tougher workpiece grades. Typical applications include slotting, plunge milling, face milling of small features and die‑shop work where controlled tool entry and stable cutting conditions are required. The combination of a short cutting length of 25 mm and an 8 mm diameter gives a compact tool geometry that performs well in confined toolpaths while keeping cutting forces manageable.

FAQ

What materials are best machined with this end mill?
The end mill DIN 844 Type NR D 8 mm (SKU 2000866469NW) is very well suited to steel and cast iron; non‑ferrous metals, stainless steels and special alloys can be machined with adjusted feeds and speeds, and the coated version improves performance on harder grades.

Can this cutter be used for plunge cutting?
Yes. The centre‑cut geometry and short flute length enable controlled plunge milling and direct axial entry, making the tool suitable for slotting and pocketing operations that require direct entry.

What are the advantages of the Weldon shank on this tool?
The Weldon shank with a drive flat provides a secure mechanical drive, reducing the risk of slippage in the holder and simplifying quick‑change setups in workshop spindles.

How does the TiCN coating affect performance?
The TiCN coating increases surface hardness and wear resistance, raising the recommended maximum workpiece strength to 1000 N/mm² and extending tool life under higher thermal and abrasive loads.

Is this cutter suitable for automated tool changers and fixtures?
Yes. The cylindrical shank with drive flat and standard Weldon dimensions are compatible with common clamping systems and automated toolholders in production and job‑shop environments.
