TECWERK End mill DIN 844 Type HR, 12 mm, HSS‑Co5 TiCN (Weldon shank)

The TECWERK end mill DIN 844 Type HR is a long‑style, centre‑cutting milling cutter designed for robust slotting and plunge work in a workshop or production setting.

• HSS‑Co5 core with durable TiCN coating
• DIN 844 Type HR long shank geometry
• Cylindrical shank with Weldon drive flat
• Centre‑cut 4‑flute for plunge and slotting

Longer tool life and consistent cutting performance

The combination of a HSS‑Co5 substrate and a TiCN surface finish reduces abrasive wear and minimises heat build‑up, resulting in a longer service interval compared with uncoated high‑speed steel. The DIN 844 geometry ensures repeatable flute form and tooth strength across batches, which stabilises process parameters in serial production. This makes the tool particularly suitable where tool life and predictable performance affect cycle times and component quality.

Secure clamping and freedom to plunge and slot

A Weldon style cylindrical shank with a drive flat provides positive torque transmission and fast tool changes in common toolholders. The cutter’s centre‑cut capability and 4‑flute design allow controlled vertical entry and efficient chip evacuation during slotting or plunge milling. With an effective cutting length of 63 mm and an overall length of 110 mm, the geometry balances reach with rigidity for deeper cuts without unnecessary vibration.

Suited materials and application limits

The cutter is assessed for materials up to approximately 1200 N/mm², with very good suitability for steel and cast materials, and conditional suitability for non‑ferrous metals, special alloys and stainless steels. Right‑hand cutting orientation supports common machining strategies, and the honed relief of the flute profile reduces the risk of built‑up edge when machining tougher workpiece grades. These characteristics assist in selecting cutting parameters that favour surface finish and dimensional control.

Workshop readiness and standards compliance

Conforming to DIN 844 ensures compatibility with established machining practices and tool inventories. The 12 mm nominal diameter and matching shank diameter facilitate straightforward mounting, while the 45° chamfer and refined flute profile improve entry behaviour and extend tool usability. For detailed machining data or assistance with toolholder selection, Metav Werkzeuge’s technical team can provide measurement charts and setup recommendations to integrate the cutter into existing processes.

FAQ

Is this cutter suitable for plunge milling in hardened steel?
The TECWERK end mill (Type HR, SKU 2000866552NW) is centre‑cut and capable of plunge milling; it is designed for workpiece strengths up to approximately 1200 N/mm², so suitability depends on the actual hardness and the chosen cutting data.

What benefit does the TiCN coating provide?
The TiCN coating on the HSS‑Co5 substrate reduces friction and improves wear resistance, which helps to extend tool life and maintain consistent cutting behaviour during longer runs.

Can the cutter be used for stainless steel (INOX) machining?
Stainless steel is conditionally suitable; the cutter can machine INOX materials but may require optimised feeds, reduced cutting speeds and appropriate coolant strategies to avoid work hardening.

Which toolholder is recommended for mounting?
A Weldon‑clamped toolholder that accepts a 12 mm cylindrical shank with a drive flat is recommended to ensure secure torque transmission and repeatable concentricity.

What does conformity to DIN 844 mean for users?
Compliance with DIN 844 confirms standardised flute geometry and dimensions, facilitating predictable performance and interchangeability within established tooling systems.
