TECWERK End mill DIN 844 Type N, Ø 5 mm – HSS‑Co8, 4‑flute, Weldon shank

A short, four‑flute end mill (DIN 844 Type N, Ø 5 mm) for precise slotting and peripheral milling in medium‑strength steels and cast parts, supplied with a Weldon shank for secure clamping

• HSS‑Co8 for enhanced wear resistance
• Short design for stable, precise milling
• Weldon shank with drive flat for secure clamping
• Suitable for steels and cast materials

High cutting performance in a compact form

The short four‑flute cutter delivers high material removal rates while keeping vibration low, which is essential for stable, accurate milling in confined spaces. The HSS‑Co8 substrate provides improved red hardness and wear resistance compared with standard high‑speed steel, making the tool well suited to interrupted cuts and tougher operating conditions. The combination of a reduced overall length and a stout shank reduces deflection, so the result is consistently tight tolerances and improved surface finish even in demanding small‑feature operations.

Reliable material suitability and cutting behaviour

Designed according to DIN 844 Type N, this cutter features a central cutting geometry and a right‑hand helix that supports plunge and peripheral cutting. The tool is specified for machining materials up to approximately 800 N/mm² with an uncoated tool, and higher up to 1,000 N/mm² when a suitable coating is applied; this rating reflects its capability on medium‑strength steels. The tool is also very suitable for cast iron and conditionally suitable for non‑ferrous metals and stainless steels. These performance indicators help planners choose feeds and speeds with confidence and avoid costly trial‑and‑error on the shop floor.

Secure clamping and practical workshop handling

A Weldon shank with drive flat ensures positive torque transfer and reliable retention in standard holders, which reduces slippage during heavy cuts and supports repeatable set‑ups. The shank diameter of 6 mm matches common collet and chuck systems, simplifying integration into existing tool inventories. Short overhang and a compact effective length contribute to lower spindle loads and extend both tool life and machine uptime, reducing the frequency of tool changes and the risk of scrapped parts due to chatter or deflection.

Application benefits and user guidance

For technicians seeking a robust, short‑reach milling solution, the tool’s four cutting edges balance chip evacuation and surface quality, resulting in efficient slotting and shoulder milling where access is restricted. When using the tool for tougher alloys or higher cutting speeds, a compatible coating can expand the working range; in many routine operations the uncoated HSS‑Co8 variant provides an attractive compromise between cost and wear resistance. It is recommended to adjust feed per tooth and depth of cut to account for the short cutting length and to use coolant where appropriate to preserve geometry and edge life.

FAQ

What materials can this short end mill machine effectively?
The TECWERK short end mill, DIN 844 Type N, performs very well on steel and cast iron; it is conditionally suitable for non‑ferrous metals and stainless steels, with higher hardness capacity when a coating is applied.

Is the Weldon shank compatible with standard toolholders?
Yes, the Weldon shank with drive flat fits common collet chucks and Weldon holders, and the 6 mm shank diameter matches standard retention systems used in small‑tool applications.

Can this tool be used for plunging operations?
The tool features a central cutting edge (Zentrumschnitt), so short plunge moves are possible; however, using moderate feeds and coolant is recommended to preserve edge life on deeper plunges.

What makes HSS‑Co8 advantageous for this end mill?
The HSS‑Co8 substrate increases red hardness and wear resistance over conventional HSS, improving tool life in interrupted cuts and elevated temperatures without the immediate need for a coating.
