Catalog number: PUMD-8.1 Features: ●There is a small diameter drill at the tip, and the second stage of the circular blade performs end mill cutting, so even thin plates and plastic resins will not crack and clean holes will be made without burrs on the back. ●A new drill that combines a centering drill and an end mill allows cutting at twice the feed speed, resulting in high efficiency. Applications: ●Cutting materials: aluminum, steel, resin and other plates, rivet pilot holes, pipes, H-shaped steel, thick plates. Specifications: ●Blade diameter (mm): 8.1 ●Groove length (mm): 84 ●Total length (mm): 117 ●Shank diameter (mm): 8.1 ●Effective machining depth: 3D (blade diameter x 3 times) Material/Finish: ●High-speed steel (HSS)
