A hand press is a sheet metal tool that performs press working by manually operating a handwheel. It is operated by pushing and turning the handwheel. Press-fitting of parts such as bearings and shafts, removal of dowels, crimping and bending of metal plates, etc. can be performed easily. Many have relatively simple structures, are easy to maintain, and can be used for a long time. Depending on the model, the impact force can be adjusted from 0 to 6,500 kg depending on the model. There are products that are suitable for striking aluminum or brass eyelets, and products that have easily moveable heads or replace parts.
