Zusammenfassung:	A drive assembly for portable, hand-held, battery powered tools is provided. The tool may be configured as a crimping tool, a cutting tool or other type of tool. The tool has an in-line handle assembly and a working head assembly. The drive assembly includes a drive assembly housing, a gear assembly, a lead drive shaft and a bearing system. The gear assembly is a multi-stage gear assembly having an input tier and an output tier. The input tier is operatively connected to a motor and the output tier is connected to a lead drive shaft. The lead drive shaft has a proximal end extending into a distal end portion of the drive assembly housing. The bearing system is positioned within the drive assembly housing adjacent the output tier of the gear assembly. The bearing system is interactive with the lead drive shaft enabling the drive assembly to withstand radial and axial loads as the lead drive shaft is rotated during an operation of the tool.
