End mill DIN 844 Type NR Ø16 mm, HSS‑Co5, Weldon shank (TECWERK)

End mill DIN 844 Type NR Ø16 mm HSS‑Co5 — a short, multi‑flute cutter designed for precision milling of steel and cast iron in industrial and workshop environments.

• End mill DIN 844, Type NR, HSS‑Co5
• 4-flute, short design with centre cut
• Weldon shank with drive flat
• Suited for steel and castings up to 800 N/mm²

Durable high-speed performance for demanding materials

The cutter is made from HSS‑Co5, offering a balance between toughness and hot‑hardness that benefits interrupted cuts and elevated temperatures during milling. The DIN 844 short profile and 4 flutes reduce vibration and increase tool life in jobbing and general production work. Rated for uncoated use on materials up to 800 N/mm², the design provides predictable performance when machining medium‑strength steels and typical cast components.

Secure clamping and centre cutting for versatile operations

A Weldon shank with drive flat ensures positive torque transmission and quick tool changes in standard holders, while the centre cutting geometry enables limited plunge operations without pre‑drilling. The 45° protection chamfer and the relief‑ground flute profile improve entry behaviour and reduce burr formation at the cut start. These features combine to give a stable, reliable cutter for short‑overhang setups in production and maintenance tasks.

Compact design that improves feed rates and stability

With a diameter of 16 mm, effective length 42 mm and overall length 92 mm, the short multi‑flute format minimises overhang and deflection, allowing higher feed per tooth and more consistent surface finish. The four cutting edges increase metal removal per revolution compared with two‑flute alternatives, which is advantageous for faster cycle times in small to medium batch runs while maintaining dimensional control.

Targeted application advice and handling notes

The tool is particularly suitable for steel and castings, where it shows very good suitability; performance on non‑ferrous metals is conditional. As supplied, the cutter is uncoated and therefore specified for work up to ~800 N/mm²; selection of a coated variant is recommended if higher strength materials (up to ~1000 N/mm² with coating) are to be machined. For optimal results, maintain short tool overhang, use appropriate coolant or lubricants for the workpiece material, and check clamping torque on the Weldon shank to avoid slippage.

FAQ

What materials is this end mill best suited for?
This TECWERK end mill is very well suited for steel and castings; performance on non‑ferrous metals is conditional and depends on specific alloys.

Can the cutter be used for plunge milling?
The tool features a centre cutting geometry allowing limited plunge cuts; for extended plunging, a dedicated full‑bottom cut design is recommended.

What does the Weldon shank provide in practice?
The Weldon shank with drive flat offers reliable torque transmission and quick secure clamping in standard holders, reducing the risk of slippage during heavy cuts.

Is a coated version available for harder materials?
This item is supplied uncoated and rated for up to ~800 N/mm²; coating increases permissible strength (up to around ~1000 N/mm²)—consult Metav Werkzeuge for coated alternatives.
