Combining ALCRONA-coated HSS‑Co PM construction with DIN 844 Type N geometry, this short Ø 8 mm Weldon end mill provides high stiffness, reliable vibration control and consistent results in steel and stainless applications; order the end mill directly via Metav Werkzeuge or ask our consultants if needed.

End mill DIN 844 Type N Ø 8 mm — HSS‑Co PM, ALCRONA-coated (TECWERK)

The End mill DIN 844 Type N Ø 8 mm is a short, centre‑cutting milling tool designed for precise machining of steel, stainless steel and cast components in shop and industrial environments

• HSS‑Co PM with ALCRONA coating
• DIN 844 Type N, centre‑cutting geometry
• 4 flutes with uneven spacing to reduce vibration
• Weldon shank for positive drive and rigidity

High‑performance material for longer tool life and edge stability

The combination of HSS‑Co PM (powder‑metallurgical high‑speed steel with cobalt) and an ALCRONA coating gives the cutter improved wear resistance and heat tolerance compared with standard high‑speed steels. For everyday production this means more consistent edge retention when machining materials up to roughly 1,000 N/mm², fewer tool changes and a steadier surface finish. The coating reduces adhesive wear and supports higher cutting loads in finishing and semi‑finishing passes, translating into measurable productivity gains in batch work and frequent operation cycles.

Stiff, short form and secure shank for precise machining

Built to the DIN 844 Type N specification and supplied in a compact short form, the tool’s geometry focuses on rigidity and positional accuracy. The Weldon shank with drive flat ensures positive clamping and torque transmission in standard toolholders, reducing the risk of slippage under side loads. As a centre‑cutting tool with right‑hand helical geometry, it permits controlled axial entry for pocketing and slotting while maintaining tight positional tolerances and repeatability across machined features.

Controlled chip flow and reduced chatter for better surface quality

The four‑flute design, combined with unevenly spaced cutting edges, actively disrupts harmonic vibration and lowers the tendency to chatter on interrupted cuts. A conical flute root increases core strength and overall tool stiffness, improving resistance to deflection under load. These features enhance chip control and improve heat dissipation, which helps to maintain consistent cutting forces and surface integrity — particularly valuable when finishing stainless steels and cast parts where tool deflection would otherwise compromise dimensional accuracy.

Suited materials and practical application advice

The cutter is optimised for machining common engineering steels and shows very good suitability for stainless steel (INOX) and cast materials, while non‑ferrous metals and certain special alloys are only conditionally suitable. Use the tool where a combination of rigidity and surface quality is required: finishing passes, precision pocketing and short‑span slotting in components with medium to high tensile strength. For best results, fit in a accurately concentric holder and favour moderate axial depths of cut in harder materials to preserve tool life and surface finish.

FAQ

What materials is this end mill best suited for?
The TECWERK end mill (End mill DIN 844 Type N Ø 8 mm) is very well suited to steel, stainless steel (INOX) and cast materials; non‑ferrous metals and certain special alloys are conditionally suitable.

Can the cutter perform axial plunging operations?
Yes — as a centre‑cutting DIN 844 Type N cutter, this tool allows controlled axial entry for pocketing and short plunge cuts.

How does the ALCRONA coating benefit machining?
The ALCRONA coating improves wear resistance and heat tolerance, extending edge life and supporting higher cutting loads compared with uncoated HSS‑Co PM tools.

Why are the flutes unevenly spaced?
Uneven flute spacing reduces harmonic vibrations and chatter, improving surface finish and dimensional stability during interrupted or varying cuts.

What shank type is supplied and what clamping is recommended?
The tool is supplied with a Weldon shank (drive flat) for positive clamping; use a concentric, securely tightened holder to preserve rigidity and repeatability.
