Hougen Manufacturing's new battery-powered Hougen-Ogura Punch-Pro Electro-hydraulic portable hole puncher 76000 model, can be easily operated on-site where electric power may not be available or high up on a man-lift where power is not readily accessible.
Although it is battery powered, it packs enough punch to generate 8.5 tons punching force and can punch round or oblong holes up to 19/32″ diameter in 15/64″ mild steel (65,000 psi tensil strength) and 19/32″ in 5/32″ stainless steel (89,000 psi tensil strength) in four seconds. The unit's throat depth is 1.02″ and it can punch flat bar, angle or channel stock.
Weighing just 16.5 pounds, the 76000 model is ideally suited for applications typically done with electric hand-held twist drills. The operator can easily position the tool when working in narrow or awkward positions by rotating the motor 360 degrees in either direction during operation. The punch can be jogged down to the center mark to confirm hole location accuracy. An auto-return mechanism returns the punch to the starting position.
Its DC magnet motor is powered by an 18V DC Lihium-ion battery that can be fully charged in 22 minutes using the included battery charger. It can punch approximately 150 holes through 15/64" mild steel on a single battery charge. Hougen offers five other Punch-Pro Electro-hydraulic portable hole punch models for making holes from 1/4″ up to 15/16″ in material 5/64″ up to 1/2″ thickness.
