Support Documentation : DownloadThis vacuum based portable drill press gives users the holding power of a magnetic drill press with the flexibility to use it on non-ferrous surfaces. The drill motor carriage puts consistent pressure on the cutting tooth, extending the life of the cutters and decreasing drill time. The easy to use air pressure button releases the vacuum to reposition the unit quickly. The tear drop control allows the cutter to easily reach corners. The Vac-Force requires 100 to 120 psi of compressed air to operate, including air needed for most air drill motors. Modified with feed stop (Drill motor sold seperately).
