20-PC TiN-Coated H.S.S. End Mill Set offers a broad selection of inch-based cutters for general-purpose machining. The set includes 2-flute and 4-flute tools, allowing machinists to match flute count to workpiece material. The 2-flute tools provide chip space suitable for aluminum, non-ferrous alloys, and wood, while the 4-flute cutters offer rigidity and improved finish in steel. All tools feature straight shanks and center-cutting geometry to support plunging, helical entry, slotting, and side milling. TiN coating enhances durability and heat resistance for extended tool life. The set is stored in a fitted wooden case for organization and protection, serving production shops, training labs, and maintenance departments.
