BF-3 Edge Mount Bi-Fold Drill

The BF-3 Bi-Fold Machine provides drilling for hardware and alignment for edge-mounted hinge applications. Doors with widths from 8” to 24”, heights from 3’0” to 8’0” and thicknesses from 7/8” to 1⅜” are supported. The standard machine is set for 1⅜” doors, though this can be specified prior to order.

Standard features include drilling either 3/8” or 7/16” diameter pivot hardware holes with a range in depth from 1” to 2”. Drills are mounted 1-1/4” from the door edge unless otherwise specified. If unequal drilling is required (either 1/4” or 3/4” offset), a special motor block may be included on the original equipment or used later to modify machines in use.

The machine design enables production at a rate of approximately 200 two-door units per eight-hour work shift with a single operator using a basic pneumatic screwdriver.
