Catalog number: PUMD-9.1 Features: ●There is a small diameter drill at the tip, and the second stage has a circular blade that cuts with an end mill, so even thin plates and plastic resins do not crack and can make clean holes 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): 9.1 ●Groove length (mm): 89 ●Total length (mm): 124 ●Shank diameter (mm): 9.1 ●Effective machining depth: 3D (blade diameter x 3 times) Material/Finish: ●High-speed steel (HSS)
