TECWerk 12 mm HSS‑Co5 DIN 844 Type HR end mill, Weldon shank

The TECWerk 12 mm HSS‑Co5 DIN 844 Type HR end mill is a short, four‑flute milling cutter designed for robust general machining and cast‑iron work up to approx. 800 N/mm² in its uncoated state

• HSS‑Co5 high‑speed steel with 5% cobalt
• DIN 844 short Type HR four‑flute geometry
• Weldon shank with drive flat for secure clamping
• Centre‑cutting with 45° protective chamfer

Reliable cutting performance for demanding materials

Constructed from HSS‑Co5, this short four‑flute cutter combines toughness and red hardness to withstand elevated cutting temperatures and higher mechanical loads. The tool is specified to process materials up to 800 N/mm² when used uncoated and, if coated appropriately, can extend capability to approx. 1200 N/mm². As a result, machining cycles are stabilised and tool changes are reduced, supporting efficient production workflows.

Secure clamping and stable chip control for precise results

The Weldon shank with a drive flat ensures positive torque transmission and reduces slippage in the holder, while the centre‑cutting geometry allows controlled plunging when required. A 45° protective chamfer and a relieved, finely ground helix profile improve chip evacuation and lower cutting forces, which contributes to consistent surface finish and reduced tendency for workpiece vibration in short‑reach operations.

Practical application guidance and material suitability

Designed to meet the DIN 844 Type HR short‑series specification, the cutter is very well suited for steel and cast iron applications, with non‑ferrous metals being conditionally suitable depending on feed and speed. The combination of the fine helix profile and right‑hand cutting direction favours stable finishing passes and semi‑roughing operations. For best results, select a coated variant when facing harder materials to exploit the higher permitted strength limit and extended tool life.
