Designed for consistent, efficient cutting in a variety of materials, this slot drill maintains precise geometry under demanding conditions. The 30° helix supports efficient chip evacuation and smooth cutting, while the 12° rake enhances shoulder milling performance. A Weldon 16 mm shank provides a secure grip in standard milling setups, reducing runout and improving part accuracy. The combination of powder-metallurgical HSS-E and a bright finish offers improved wear resistance and a dependable tool life, making it a solid choice for deep slots, pockets, and shoulder features in free-machining steels, copper alloys, and challenging high-temperature alloys.
