8mm Carbide Tipped End Mill Short 25mm Cutting Length HSS-Co5, DIN 844 Weldon Shank - TECWERK

Combining the heat resistance of HSS‑Co5 with a secure Weldon shank, this short multi‑flute end mill gives consistent chip evacuation and stable performance in steel and cast iron; order the cutter directly via Metav Werkzeuge or consult our specialists for machining advice.

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

A End mill DIN 844 Type NR for short, high‑precision milling in medium‑strength steels and cast iron, featuring a 25 mm effective cutting length and a robust Weldon shank.

• HSS‑Co5 high‑speed steel construction
• DIN 844 Type NR, short multi‑flute design
• 25 mm effective cutting length, 45° chamfer
• Weldon shank with drive flat for secure clamping

Stable performance in medium‑strength materials

The HSS‑Co5 composition raises red hardness and toughness compared with conventional high‑speed steels, resulting in more reliable edge retention under heat. With an 8 mm diameter and 25 mm effective cutting length, this cutter is designed for efficient pocketing and face milling operations in materials up to approximately 800 N/mm² in its uncoated form. The DIN 844 geometry and central cutting capability allow plunge operations and precise entry into the workpiece, reducing the need for pre‑drilled starts and simplifying setup for series production.

Secure clamping and vibration control for consistent results

A Weldon shank with a drive flat ensures positive engagement in the toolholder and reduces the risk of slippage during heavy intermittent cuts. The short, multi‑flute layout (three cutting edges) and the 45° protection chamfer together improve chip evacuation and lower radial cutting forces, which helps to avoid chatter on less rigid setups. The relieved flute profile provides a controlled cutting edge, delivering dimensional stability and repeatable surface quality across runs.

Predictable tool life and process economy

Supplied uncoated, this cutter offers a reliable baseline for many workshop applications; the cobalt alloy increases resistance to work‑hardening and thermal softening, extending useful life compared with plain HSS. Tool reconditioning is straightforward thanks to the classic geometry and accessible flute design, which keeps down total cost of ownership for medium‑volume production. Suitability assessments: steel – very well suited; cast iron – very well suited; non‑ferrous metals – conditionally suited, depending on feed and speed adjustments.

FAQ

What materials is this end mill suitable for?
The TECWERK end mill (DIN 844 Type NR, SKU 2000866465NW) is very well suited for steel and cast iron; non‑ferrous metals are conditionally suitable with adapted feeds and speeds.

Can this cutter be used for plunge milling?
Yes, the central cutting geometry of the tool permits plunge cutting, allowing direct entry into the workpiece without pre‑drilling for many applications.

Does the tool come coated?
This particular item is supplied uncoated; the HSS‑Co5 substrate still offers improved heat resistance, and coated variants can be considered where higher surface speeds are required.

What holder is recommended for secure clamping?
A toolholder that accommodates a Weldon shank with a matching drive flat is recommended to ensure secure clamping and to prevent rotation under load.
