July 14, 2016 - Hougen Manufacturing, Swartz Creek, Mchigan, has introduced a new battery-powered Hougen-Ogura Punch-Pro Electro-hydraulic portable hole puncher. The new battery powered unit, 76000PR 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 11 tons punching force and can punch round or oblong holes up to 19/32 in. diameter in 1/4 in. mild steel in 4.5 seconds. The unit’s throat depth is .98 in. and it can punch flat bar or angle iron.

Weighing just 17.4 lbs the 76000PR cordless hole puncher 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. The model includes the new “Power Retractable” Punch system which allows the user to power reverse the punch back out of hole. This improves productivity in harder, more elastic materials which tend to grip the punch (not allowing it to auto return to the home position) after the hole is produced. 

Its 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 1/4 in. mild steel on a single battery charge. Hougen offers other models of Electro-hydraulic portable hole punchers for making holes from 1/4 in. up to 15/16 in. in material 5/64 in. up to 1/2 in. thickness.
