Battery driven electric power tool with brushless motor

An electric power tool comprising:

• a power source enclosed in a casing, wherein the power source is a brushless DC motor;
• a drive mechanism for a cutting device, wherein the drive mechanism comprises a central shaft and a spring clutch assembly and is driven by the brushless DC motor, wherein the central shaft, spring clutch assembly and DC brushless motor share a common axis, wherein the central shaft extends from the DC brushless motor into the spring clutch assembly;
• an oil pump, wherein the oil pump is at least partly housed in the casing of the electric power tool;
• and
• a brake assembly, wherein the brake assembly comprises a collar member provided with a projecting lug such that a brake lever is selectively engageable with the projecting lug,
• wherein the oil pump is driven by the brushless DC motor.
