• Flutes: 2-flute configuration for efficient chip evacuation and stable cuts
• Length of cut: 13 mm
• Overall length: 57 mm
• Shank: 6 mm Weldon flat for secure clamping and torque transfer
• Material: HSS-E powder metallurgy with bright finish for enhanced wear resistance
• Helix angle: 30° to promote smooth chip formation and evacuation
• Rake angle: 12° to improve cutting action in shoulder milling and slotting
• Standards: DIN 844 K compatibility for broad tooling compatibility
• Applications: Shoulder milling, slot milling, and ramping in steel, cast steel, and copper/copper alloys

Designed to deliver durable, precise slots and clean shoulders, this slot drill minimizes deflection and maintains consistent diameters through moderate depths. The combination of HSS-E powder metallurgy and a bright finish provides wear resistance and long tool life, while the 30° helix and 12° rake angle enhance cutting efficiency and surface finish. The Weldon flat shank ensures a secure grip in standard chucks and collets, helping you maintain tight tolerances in demanding workpieces.
