25mm Helical End Mill HSS-Co5 TiCN Coating 63mm Effective Length, DIN 844 - TECWERK

Take advantage of a robust HSS‑Co5 construction and a TiCN coating for extended life and consistent results in demanding milling tasks; order the cutter directly via Metav Werkzeuge or consult the specialists if required.

TECWERK end mill DIN 844 Type HR – Ø 25 mm, HSS‑Co5, TiCN, Weldon shank

The TECWERK end mill DIN 844 Type HR is a short, four‑flute HSS‑Co5 cutter designed for rigid milling of steel and cast iron in general workshop and industrial applications.

• HSS‑Co5 for high wear resistance
• TiCN coating extends tool life
• 25 mm Weldon shank for secure clamping
• Short 63 mm effective length for rigidity

High‑speed steel and coating: precision where it counts

The short‑fluted cutter is produced from HSS‑Co5, a cobalt‑alloyed high‑speed steel engineered for improved red‑hardness and abrasion resistance, which translates into longer service life under elevated temperatures. The additional TiCN coating reduces friction and increases surface hardness, improving performance when finish quality matters. Certified to DIN 844, the tool’s geometry and tolerances conform to recognised workshop standards, helping maintain repeatability in serial production. Together these aspects reduce downtime and tool changes, supporting efficient workflows.

Rigidity and cutting geometry for reliable metal removal

With a four‑flute layout and centre cutting capability, the cutter permits axial plunging and stable side milling. The Weldon shank provides secure torque transfer in clamping systems, while the 45° chamfer protects the cutting edges during engagement. The specification supports machining of common steels very well and cast iron very well; the tool handles materials up to approx. 800 N/mm² with uncoated edges and up to 1200 N/mm² when the coating is applied, offering a clear technical lead for medium‑hard workpieces. These properties minimise chatter and improve surface finish in short‑overhang setups.

Workshop benefits and application guidance

The short design with a 63 mm effective length and a compact overall form gives high stiffness for interrupted cuts and slotting in constrained setups. A finely honed relief profile reduces burr formation and eases deburring after machining, particularly in ferrous materials. While non‑ferrous alloys and special alloys are conditionally suitable, the cutter excels in standard workshop steel and cast iron tasks. For selecting optimal feeds and speeds or matching holders, Metav’s technical guidance is available to align cutter choice with machining strategy and machine capability.

FAQ

What materials is this cutter best suited for?
The TECWERK end mill (Type HR) is very well suited to machining steel and cast iron; non‑ferrous and special alloys are conditionally compatible depending on process parameters.

Can the cutter perform plunge cutting?
Yes. The centre‑cutting geometry allows axial plunging; the four‑flute layout supports stable side milling as well.

How does the TiCN coating affect performance?
The TiCN coating reduces friction and raises surface hardness, extending tool life and enabling machining of harder steels up to around 1200 N/mm² with the coated tool.

What clamping is recommended for best rigidity?
A firm Weldon‑shank clamping system is recommended to take full advantage of the cutter’s stiffness and to minimise run‑out during aggressive milling.

Is this tool standardised?
The cutter complies with DIN 844 specifications for Type HR short end mills, ensuring consistent geometry and interchangeability.
