• Overall length: 49 mm
• Series: Extra-short (short series) for precise control in limited-depth pockets
• Shank: 6 mm Weldon shank
• Material & coating: Powder-metallurgical HSS-E with Alcrona Primax coating for improved wear resistance and reduced friction
• Flutes: 3-flute design for stable cutting and efficient chip evacuation
• Helix & rake: 30° helix and 12° rake angle optimize cutting action, chip flow, and surface finish
• DIN standard: DIN 327 D compatibility for reliable tooling fits
• Applications: Shoulder milling, slot milling, and ramping across steel, cast steel, cast iron, copper alloys, and titanium alloys

This slot drill is crafted to deliver consistent slot dimensions and clean shoulders, even in demanding materials. The 3.0 mm diameter, combined with the short length of cut, provides precise entry and controlled depth, making it ideal for fabrications, prototyping, and production environments where tight tolerances matter. The Alcrona Primax coating reduces wear and extends tool life, while the powder-metallurgical HSS-E substrate handles tough cutting with resilience. Use this tool to achieve smooth slotting, accurate shoulder milling, and efficient ramping in a wide range of metallic workpieces.
