The magnetic drill hinge hole can be used as the bolt hole of the main engine seat, but it should be noted that

The cutting ability of magnetic drill is limited, so it is necessary to choose suitable reamer and cutter to ensure proper cutting edge angle and good chip cleaning.

In the process of using magnetic drill and reamer, it is necessary to prevent foreign matter from entering the threaded hole as much as possible to avoid damaging the threaded hole on the surface of the main engine seat.

Before drilling, the drilling depth must be determined according to the specifications of the main engine seat, and appropriate fixing methods should be adopted, such as fixing the magnetic drill on the drilling site with a magnetic base.

It is necessary to select the appropriate coolant according to the material and requirements of the main engine seat, and clean the chips and coolant in time.

Using magnetic drilling reaming can provide an effective processing method for the bolt hole of the main engine seat, but attention should be paid to the safety and precautions in the operation.
