TECWERK End mill DIN 844 Type HR – 8 mm, HSS‑Co PM, ALCRONA‑coated

The TECWERK short 4‑flute end mill is designed for robust milling of steels and stainless materials, offering centre‑cutting capability and a Weldon shank for reliable clamping in industrial toolholders.

• HSS‑Co PM substrate with ALCRONA coating
• DIN 844 Type HR short 4‑flute geometry
• Weldon shank with drive flat
• Suited for materials up to ≈ 1400 N/mm² tensile strength

Consistent performance in demanding steel machining

The HSS‑Co PM core provides a balance of toughness and wear resistance that benefits interrupted cuts and high‑load operations. With ALCRONA surface treatment, the tool shows improved resistance to adhesive wear and reduced built‑up edge, which extends service intervals and maintains surface finish quality. This combination is especially effective when machining steels and stainless materials that approach the upper tensile range indicated for the cutter. The result is predictable tool life and fewer unscheduled tool changes, supporting smoother production flow.

Rigidity and control for accurate features

Short overall geometry and a 4‑flute layout enhance stiffness and reduce overhang‑related deflection, which helps preserve dimensional accuracy in pocketing and contouring tasks. The 45° chamfer on the cutting edge gives a defined engagement that softens entry effects while the conical flute root increases shaft stiffness; together they reduce chatter and improve repeatability when producing milled features. For jobs requiring precise depths and clean edges, the cutter’s reduced projection and stiff design contribute directly to part quality.

Secure clamping and straightforward integration on the shop floor

A Weldon shank (drive flat) ensures positive drive transfer to standard toolholders, allowing rapid tool changes without complex adaptors. The 10 mm shank diameter and compact overall length reduce the need for long extensions, lowering the chance of vibration. Centre‑cutting geometry permits limited plunge operations, and the cutter is specified for reliable machining of steel, stainless steel and cast materials—non‑ferrous and certain special alloys are conditionally compatible. For complex applications or material mixes, Metav Werkzeuge’s technical team can supply additional cutting‑data guidance and holder recommendations.

FAQ

Is this cutter suitable for stainless steel applications?
The TECWERK end mill is specified as very well suited for INOX; the HSS‑Co PM substrate and ALCRONA coating help maintain edge life and surface quality when machining stainless materials (SKU 2000866057NW).

Can this cutter perform plunge cuts?
Yes, the tool features centre‑cutting geometry, which allows limited plunge operations; the cutting length of 4 mm supports short plunges and entry cuts.

Which clamping system is required for this tool?
The cutter has a Weldon shank with a drive flat and a 10 mm shank diameter, designed for secure clamping in Weldon holders and standard setscrewed toolholders.

For which materials is this end mill optimised?
Optimised for steels and stainless steels (very good suitability) and cast materials; non‑ferrous metals and special alloys are conditionally suitable depending on cutting conditions.

How does the ALCRONA coating improve performance?
ALCRONA reduces adhesion and thermal wear on the cutting edges, extending tool life and improving consistent surface finish during prolonged milling of tougher materials.
