-Drilling and countersinking holes for screws can be done in one operation, resulting in highly efficient machining (countersink type)
-Since relief holes can be drilled at the same time as drilling pilot holes for power strips, it is ideal for drilling pilot holes in thick panels that require relief (single-cut type).

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.
