16mm Solid Carbide End Mill DIN 844 HR 4-Flute Long 45° Chamfer Alcrona Coated HSS-Co PM, Weldon Shank - TECWERK

Benefit from a combination of HSS‑Co PM construction, an ALCRONA coating and a secure Weldon shank that delivers reliable milling performance in high‑strength steels; order the tool directly via Metav Werkzeuge or request consultant support for application-specific guidance.

End mill DIN 844 Type HR Ø16 mm — HSS‑Co PM, ALCRONA‑coated, Weldon shank (TECWERK)

The End mill DIN 844 Type HR Ø16 mm is a long, four‑flute, centre‑cutting shank cutter designed for machining high‑strength steels and stainless materials with improved rigidity and secure clamping.

• HSS‑Co PM grade for high wear resistance
• ALCRONA coating for extended tool life
• Weldon shank with drive flat for secure clamping
• 4‑flute long design with centre cutting

Heavy‑duty performance for tough materials

This long DIN 844 cutter is engineered from HSS‑Co PM, a powder‑metallurgy high‑speed steel alloy that combines toughness with thermal stability. The specification enables effective machining of high‑strength steel up to approximately 1400 N/mm² tensile strength and gives very good results on stainless steel and cast iron. Where non‑ferrous metals or special alloys are involved, the tool is conditionally suitable; suitable machining parameters and coolant strategies should be selected to maintain performance. The material and geometry translate into predictable tool life and consistent part quality in industrial applications.

Geometry that increases stability and cutting reliability

The long 4‑flute layout with a conical flute root improves overall stiffness compared with straight flute bottoms, which reduces deflection during deep cuts. The Weldon shank with drive flat ensures secure clamping in standard toolholders, lowering the risk of slippage under load. Centre‑cutting geometry permits axial engagement for light plunging where required, expanding setup flexibility. These design elements together result in reproducible margins and reduced rework in production runs.

Coating and edge protection for longer productive life

The ALCRONA coating provides a hard, wear‑resistant surface that reduces built‑up edge formation and improves thermal resistance during interrupted cuts. A 45° protection chamfer at the tool entry diminishes the risk of edge chipping and supports smooth entry into workpieces, while the right‑hand cutting orientation matches common milling conventions. These features reduce the frequency of tool changes and support stable surface finish when machining demanding materials.

Practical application and handling notes

As a long version end mill, attention to overhang and clamping length is advised to preserve the blade geometry and to benefit from the tool’s enhanced rigidity. Use appropriate holder clamping and monitor runout when installing the cutter in the spindle; this maximises life and maintains dimensional accuracy. The TECWERK cutter is supplied as a single unit and is suited to workshops and production environments that require a robust, versatile cutter for steel and stainless applications.

FAQ

What materials is this end mill best suited for?
The TECWERK end mill (DIN 844 Type HR, Ø16 mm, SKU 2000866076NW) is optimised for high‑strength steel, with very good suitability for stainless steel and cast iron; non‑ferrous metals and some special alloys may require adjusted parameters.

Is the cutter suitable for plunge milling?
Yes, the centre‑cutting geometry permits light axial engagement; the centre‑cut feature of this DIN 844 long cutter supports limited plunging operations.

How does the ALCRONA coating benefit production?
The ALCRONA coating increases surface hardness and reduces built‑up edge formation, which extends tool life and stabilises surface finish under typical milling conditions.
