Product Description

[Features]
·Drilling and counterbore processing can be performed in 1 process for bolt hole processing, realizing highly efficient processing (Counterbore type)
·Since relief hole can be drilled at same time as drilling power strip pilot hole, it is ideal for drilling pilot hole in thick plates that require relief (Incision 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.
