The GHD-22A Industrial Drilling Machine features a 3 Morse Taper spindle geared head rather than a pulley and belt drive system, making adjusting speed faster and simpler.  
Using this machine is straightforward, thanks to its large cast table with 14mm T-slots, which rotates 360 º and uses a rack and pinion to adjust its height. Drilling speeds vary from 105 to 2900rpm and, there is a drill depth stop for accurate and repeatable drilling.
