We offer several different punch clamp tools for different service requirements. We have two "pocket" size tools for field or infrequent repair (the N60-38 is economical and the N70-S038 is more heavy duty). The N60-1 & N70-T300 are more suitable for service repair or production lines where more clamping will occur (they are just 2 different mfg brands depending on user preference). Lastly, the N60-TA3 is a standup production machine for faster, easier assembly (also available for rental where a range of assemblies must be done on-site). Assembly instruction sheets are provided with the tools.
