Hollow drill also known as core drill, hole opener, center drill, steel plate drill, magnetic drill, rail drill and so on.
The main materials of drill are: high speed steel; Powder metallurgy; Cemented carbide.
Hollow drill types and specifications are complete, suitable for all kinds of imported magnetic seat drill (magnetic drill) and general drilling, milling, boring, etc. The drilling efficiency is 8~10 times that of ordinary drill.
Hollow drill (multi blade steel drill or core drill) is more efficient bit of annular cutting blade, the hole diameter from 12 mm to 150 mm, it is mainly used for drilling of steel members, such as steel structure engineering, rail transportation, Bridges, ships, machinery manufacturing, aerospace, and other areas of the hole drilling, the drilling performance is superior to the traditional two blade twist drill, With the characteristics of high drilling efficiency, light drilling and labor-saving, multi-blade steel plate drill and magnetic seat drill can be used for multi-directional drilling of large workpiece, convenient and flexible operation, effectively shorten the construction time, and become the preferred tool for drilling and annular groove processing of modern steel components [1].
