Knockout Punches

Slug-O-Ster knockout punches are a boon for panel manufacturers, electrical contractors, and for offshore projects. Knockout punches are very useful for punching big holes in sheet metal and panels, a job which is otherwise difficult, tedious, and time consuming, more so, when the panel size is very big. It is just unsurpassable for punching such holes on existing panels at site. Slug-O-Ster can punch holes within a minute, ranging from 12 mm to 125 mm dia in sheet metal thickness up to 10 gauge (3 mm approx.). Special punches can be supplied for making holes of square, rectangular, or other shapes as desired. These are available in wrench-driven, hand, hydraulic, or electro hydraulic models. Benefits of hydraulic knockout punch driven with hand pump over wrench-driven knockout punches: fast, easy, and simple to operate, it punches holes three time faster than wrench method; takes very less amount of cutting load; life of stud is more found; cutting in the corner of panel or where one cannot rotate the wrench easily, and the use of hand hydraulic is necessary.
