End mill DIN 844 Type N, 5 mm — HSS‑Co8, TiCN, Weldon, 4‑flute (short) — TECWERK

The End mill DIN 844 Type N, 5 mm is a short, four‑flute HSS‑Co8 cutter with TiCN coating and a Weldon cylindrical shank, engineered for milling medium‑strength steels and stainless steel with reliable axial entry.

• HSS‑Co8 construction for high toughness
• TiCN coating for extended tool life
• Weldon shank for secure clamping
• Four flutes with centre‑cut entry

High‑performance cutting for medium‑strength materials

The short HSS‑Co8 body combined with a TiCN surface treatment offers a balance of toughness and wear resistance that is well suited to workshop and small‑series production. The cobalt‑alloyed high‑speed steel substrate maintains edge stability under elevated temperatures, while the hard, low‑friction coating reduces built‑up edge and extends usable life. This combination means fewer tool changes during runs and more consistent dimensional results on parts made from carbon and alloy steels.

Geometry engineered to improve surface finish and efficiency

A four‑flute configuration with centre‑cut geometry provides good chip evacuation and allows axial plunging when required, improving process flexibility. The short design reduces overhang and diminishes chatter, which benefits both surface quality and dimensional accuracy during finishing passes. The cutter’s DIN 844 Type N profile is optimised for general milling tasks, translating into reliable performance in both slotting and peripheral milling operations.

Secure clamping and stable machining

The Weldon shank (cylindrical shank with driving flat) ensures a positive mechanical drive and minimal slippage in the toolholder, which is particularly important for short, high‑precision cutters operating at higher spindle speeds. Right‑hand cutting geometry and the compact form factor combine to reduce vibration and runout, supporting repeatable hole entries and tight tolerances in serial manufacture. Suitable clamping and correct speed/feed settings will further reduce micro‑chatter and prolong the tool life.

Broad application range and clear material guidance

This cutter is specified for machining materials up to approximately 800 N/mm² with an uncoated tool and up to 1000 N/mm² when used with the TiCN‑coated version; the specification reflects the tool’s capacity across common workshop steels. The tool is listed as very good for steel, very good for stainless steel and cast iron, with conditional suitability for non‑ferrous metals and special alloys. For best results, match coolant and feed rate to the workpiece and monitor chip formation to avoid premature abrasion.

FAQ

Which materials is the end mill best suited for?
The TECWERK End mill DIN 844 Type N, 5 mm (SKU 2000866350NW) is rated very good for steel, stainless steel and cast iron, with conditional suitability for non‑ferrous metals and special alloys.

Can the cutter be used for axial plunging?
Yes, the centre‑cut geometry allows axial entry; the short, four‑flute design supports controlled plunging and improved chip evacuation during such operations.

What are the advantages of the Weldon shank?
The Weldon cylindrical shank provides a driving flat for secure clamping, reducing slippage and runout risk during high‑precision milling tasks with the TECWERK cutter.

How does the TiCN coating affect performance?
The TiCN coating increases surface hardness and lowers friction, extending tool life and enabling machining of materials up to approximately 1000 N/mm² compared with about 800 N/mm² for the uncoated variant.
