Designed for dependable performance, this slot drill delivers clean slots and accurate shoulders with controlled chip evacuation. The 30° helix and 12° rake angle optimize cutting action, reducing resistance and improving surface finish across a range of hard and ductile metals. The 2-flute geometry balances material removal with rigidity, making it suitable for precise pockets, slots, and ramping operations. Its Weldon 12 mm shank ensures secure clamping in standard tool holders, while the powder-metallurgical HSS-E core provides enhanced wear resistance and edge retention for longer tool life in demanding machining tasks.
