4mm Corner Rounding Cutter HSS-Co8 3-Flute Short 40° Spiral, DIN 844 - TECWERK

Take advantage of a purpose‑built short slot cutter in HSS‑Co8 and three‑flute geometry to machine long‑chipping aluminium and other non‑ferrous metals with consistent results; the combination of centre cutting, a Weldon shank and a 40° helix ensures secure clamping and efficient chip control. Order the tool directly via Metav Werkzeuge or consult the technical team for material‑specific recommendations.

TECWERK slot cutter DIN 844 Type W, 4 mm — HSS‑Co8, 3‑flute, short

The TECWERK 4 mm slot cutter (Type W) is a short, three‑cutting‑edge tool designed for milling slots and grooves in long‑chipping aluminium and non‑ferrous metals

• HSS‑Co8 for increased heat resistance
• DIN 844 Type W, short design
• Three‑flute geometry for smooth chips
• Weldon shank with drive flat for secure clamping

Precision where long‑chip materials demand consistency

The short three‑edge milling geometry offers a balance between rigidity and chip evacuation that is particularly useful when working with long‑chipping alloys. Constructed from HSS‑Co8, the cutter resists thermal softening during interrupted cuts, preserving the cutting edge and reducing wear. The 40° helix promotes smooth engagement with the material, while the centre cutting tip allows limited plunge operations without the need for a separate drill, improving setup efficiency and shortening cycle times.

Material suitability and machining benefits

Engineered for non‑ferrous applications, the tool excels on long‑chipping aluminium and similar metals where consistent chip formation is critical. The three‑flute design supports even chip distribution and reduces the risk of built‑up edge, which in turn produces cleaner slot walls and a finer surface finish. The cutter’s short configuration increases stability under lateral load, yielding repeatable slot dimensions in series production or prototyping environments.

Secure clamping and reliable tool handling

A Weldon shank with drive flat and a nominal shank Ø 6 mm ensures positive drive and minimises slip in standard collets and chucks. The modest overall length and an effective length tailored for slotting applications reduce overhang and vibration, contributing to dimensional stability and improved tool life. Right‑hand cutting direction matches conventional machining setups, simplifying integration into existing processes.

Practical application notes and setup recommendations

For best results, select feeds and speeds suitable for long‑chipping aluminium alloys and ensure consistent coolant or air blast to evacuate chips. The tool’s DIN 844 Type W form and centre cutting capability make it suitable for operations where a compact cutter must deliver both plunge and peripheral milling. Maintenance of clamping surfaces and correct torque on the tool holder will preserve the clamping benefits delivered by the Weldon shank and support sustained accuracy.
