A power tool with an ergonomic handgrip comprising: a housing with a rear end portion, a first front end portion, a second front end portion, and lateral sidewalls, the housing defining a tool axis(X-X) and includes a motor housing portion and a transmission housing portion; a motor disposed in the motor housing portion; a working end coupled to the front end portion of the housing, and configured to be driven by the motor; a handle with a proximal portion coupled to the housing, a distal end portion away from the housing, a rear wall portion, a front wall portion(43,59), and a pair of sidewalls, the handle defining a handle axis(Y-Y); a trigger coupled to the handle, the trigger defining a trigger axis(Z-Z) extending in a direction of trigger movement; a first gripping region; a second gripping region including a convex surface on the rear wall portion of the proximal portion of the handle; a third gripping region on the second front end portion of the housing and offset rearward from first front end portion; a fourth gripping region on the rear end portion of the distal portion of the handle; a fifth gripping region on the front wall portion(43,59) of the distal portion of handle adjacent the trigger; and a sixth gripping region on the front wall portion of the distal portion of the handle, distal of the fifth gripping region, wherein the handle has a first depth, a second depth from the fifth gripping region to the fourth gripping region, and a third depth from the sixth gripping region to the fourth gripping region, the first depth being greater than the second depth, and the second depth being greater than the third depth, and wherein the handle has a first width between the sidewalls at the trigger, a second width between the sidewalls at the fifth gripping region, and a third width between the sidewalls at the sixth gripping region, the first width being less than the second width, and the second width being approximately equal to the third width; characterised in that the first gripping region includes a rear concave recess which wraps around the rear end portion of the housing and a lateral concave recess which extends along most of the length of the transmission housing portion along one of the lateral side walls of the housing generally parallel to the tool axis(X-X) wherein the rear concave recess is in communication with the lateral concave recess; wherein the convex surface of the second gripping region is generally defined by an ellipse centred at a centre point that is proximate to the trigger axis(X-X) and that is positioned below and in front of the trigger; wherein the first depth is from the trigger to the convex gripping surface. a housing with a rear end portion, a first front end portion, a second front end portion, and lateral sidewalls, the housing defining a tool axis(X-X) and includes a motor housing portion and a transmission housing portion;
