The 3-flute design supports efficient chip evacuation in slot milling, helping maintain clear cuts and steady feeds. The Alcrona Primax coating reduces wear and built-up edge, extending tool life and promoting consistent finishes across runs. Powder-metallurgical HSS-E provides a balance of hardness and toughness ideal for demanding metals, while the flatted shank delivers stable, precise seating in standard tool holders. With a generous reach and neck relief, this slot drill enables deeper pockets and reliable ramping without sacrificing rigidity, making it well-suited for both precision prototypes and small-batch production tasks.
