Inline Cut-Off Tool

Abstract

A family of power tools provided, the power tools including a common back-end assembly comprising a tool housing, a motor disposed within the tool housing, a peripheral switch, and other features that are substantially the same on the common back-end assembly; and distinct front-end assemblies securely mounted to the back-end assembly. The family of power tools provide significantly high power-to-weight and power-to-volume ratios. In at least one tool, a ratio of a maximum power output produced by the spindle to an overall weight of the power tool is at least approximately 0.52 watts/g when the battery pack has a maximum voltage of 20 volts and an impedance in the range of approximately 67 to 75 mOhms.
