More Information
● Boring and counterboring processes when drilling bolt holes can be done in a single step to realize a high-efficiency process. (Counterbore Model)
● When drilling pilot tap holes, a relief hole can be drilled at the same time, which is ideal for drilling pilot holes in thick sheet metal to provide scrap clearance. (Cutting Model)
● Designed for very frequent drilling of pilot holes for M4 – M12 metric coarse thread.
● High-efficiency hole drilling is achieved by reducing the chamfering process.
