20mm Slot Cutter DIN 327D Type N HSS-Co8 TiCN Coated, Short Z2 Weldon Shank - TECWERK

Take advantage of a combination of HSS‑Co8 base material and TiCN coating for extended tool life and higher cutting speeds, together with a short two‑flute geometry that ensures accurate keyway and slot machining; order the cutter via Metav Werkzeuge or consult the technical team for specification support.

Keyway cutter DIN 327D Type N — 20 mm, HSS‑Co8, TiCN, Weldon shank (TECWERK)

Keyway cutter DIN 327D Type N designed as a short, two‑flute slot cutter for precision keyways, narrow fits and deep keyseat milling in steels and stainless steel

• HSS‑Co8 for high thermal resistance
• TiCN coating for superior wear resistance
• Short two‑flute geometry for precision fits
• Weldon shank, 20 mm diameter

Precision slotting for tight keyways and form‑fit grooves

The short two‑flute geometry with centre cutting capability delivers consistent axial engagement and reduced vibration when machining tight keyways and narrow fits. The DIN 327D Type N profile is optimised for form‑fitting grooves and passkey slots where positional accuracy and surface quality are essential. The compact length lowers overhang and minimises deflection, producing repeatable dimensions and helping to meet close tolerance requirements in series and single‑part production.

Durable high‑speed cobalt with TiCN for longer tool life

Built from HSS‑Co8 and finished with a TiCN coating, the tool combines substrate toughness with a hard, low‑friction surface layer. This pairing increases resistance to abrasive wear and reduces built‑up edge on challenging materials, which supports higher cutting speeds and extended tool life under intermittent and continuous cutting conditions. The coating also improves chip flow and thermal stability, making the cutter suited to demanding production runs where downtime and tool changes must be reduced.

Secure clamping and rigid mounting for consistent results

The Weldon shank with drive flat provides a positive mechanical drive and reliable anti‑rotation in standard toolholders. A 20 mm shank diameter together with the short design enhances rigidity in the spindle and reduces run‑out, which is critical when machining deep slots or passkey grooves. Right‑hand cutting and the two‑edge geometry promote efficient chip evacuation while maintaining cutting stability on both milling centres and vertical machining operations.

Material suitability and practical machining guidance

The tool is specified for machining workpieces with low to medium strength up to approximately 1000 N/mm²; it is very well suited to steel, stainless steel (inox) and cast iron, while performance with non‑ferrous metals and certain high‑grade alloys is conditional. The flute length (free grind) of 19 mm defines the effective cutting depth for slotting tasks. For best results, select appropriate feeds and speeds in line with the substrate and machine rigidity; coolant use and short axial passes help manage heat and maintain dimensional integrity.
