MACHINERY: Vacuum Holddown Portable Drill
Click photo to enlarge• GISON Machinery Ltd., Taichung, Taiwan, offers the GPD-231, a new portable drilling machine that eases vertical, horizontal and straight-into-surface drilling by leveraging innovative vacuum-suction technology
The unit works on a variety of surfaces, including natural stone, steel, lumber, plywood and cement – no matter if the surface is smooth, rough, wet, greasy or dusty.
The 21-lbs. drill uses a 4HP air compressor for three 8.5cm suction cups, and operates without the need for an additional vacuum pump. It operates at 1,500 rpm with a maximum drill bit size of 125mm; and uses a ruler for the control of drill depth. Unlike the traditional drill machines, drilling depth is controlled by a depth-stop spindle.
