With its 2-flute geometry and powder-metallurgical HSS-E core, this drill delivers efficient chip evacuation and robust wear resistance for dependable slot creation. The bright finish helps reduce built-up edge and improve surface quality, while the 30° helix and 12° rake angle optimize cutting action for smoother ramps and cleaner shoulders. The DIN 844 K standard Weldon shank ensures a secure, true fit in standard toolholding, minimizing runout and vibration. Ideal for professional workshops and fabrication shops, this drill supports consistent performance across multiple materials, including copper alloys and steel components that require precise slots and shoulders.
