The machine body is with height adjustment. Its suitable for both long and short annular cutters as well as general chuck which is for holding drill with straight handle.
The body height adjustment enables the machine to use different length of the annular cutters. If the height of the working space is without limit, using long type annular cutter is smoother for removing metal chips from the cutter.
The general chuck is applicable for holding drill which is with straight handle for drilling smaller holes (from 2-13 mm).
The machine body can be lowered to 197mm to get in the small space of the object for drilling work.
The angle of the drilling handle is adjustable, so the operator can choose suitable handle angle for drilling.
The rotating disk can be used for adjusting drilling position, the ranges are front/rear 16mm and left/right 50mm.
The cutter lifting tube is with tooth row design which is stronger and more durable than the old slide plate type.
