This short-series slot drill leverages powder-metallurgical HSS-E for enhanced toughness and wear resistance, helping it stand up to repeated passes in demanding materials. The 2-flute design promotes efficient chip evacuation and stable cutting in narrow slots, while the 30° helix and 12° rake angle optimize cutting action for cleaner shoulders and reduced burr formation. The 10 mm Weldon shank ensures secure clamping in compatible toolholders, enabling precise, repeatable results. DIN 844 K compliance means easy compatibility with common tooling systems, reducing setup time in production environments. Ideal for engineers and machinists tackling slot milling, shoulder milling, or ramping tasks in steel, cast steel, and copper alloys.
