The Showa Super Drill system, distributed by ERI America, allows for precision drilling of holes up to 15 times their diameter from 50 — 270mm (1.97 — 10.63"), to a maximum depth of 1800mm (70.86"). It uses a combination of a center drill that creates its own pilot hole, a roughing blade, and a finishing blade which create small chips for ease of removal. While the basic set includes a head, shank, center drill, roughing blade, and finishing blade, Showa's modular design allows for use of 10 head sizes, 4 shank styles, and a wide variety of extension arbors, center drills, roughing and finishing blades. The Super Tool allows you to maximize your flexibility and productivity without overcommitting to your tool room inventory. Blades and drills are manufactured from sintered HSS for excellent performance and edge holding; sharpening is simplified thanks to the modular design and our available re-grinding fixture.
