Application Of Hollow Bit
Nov 07, 2018

Hollow drill (multi-edged steel plate drill or coring drill) is an efficient multi-edge ring cutting drill. The diameter of drill hole is from 12 mm to 150 mm. It is mainly used for drilling steel components, such as steel structure engineering, rail transit, bridge, ship, machinery manufacturing, aerospace and other hole processing fields. Its drilling performance is obviously better than transmission. The traditional two-edge twist drill has the characteristics of high drilling efficiency, light drilling and labor saving. The multi-edge steel plate drill and magnetic base drill can drill holes in many directions for large workpieces. It is convenient and flexible to operate and can effectively shorten the construction time. It has become the preferred tool for drilling and annular groove processing of modern steel components.
