Rotary power tool

1. A power tool comprising:

a motor housing including an elastomeric cover having a first lip portion;

a motor positioned in the motor housing and configured to rotatably drive an output shaft;

a handle coupled to the motor housing; and

a vibration damping assembly including a first coupling portion defined by the motor housing, a second coupling portion defined by the handle, and an elastomeric damper captured between the first coupling portion and the second coupling portion;

wherein the first coupling portion includes a boss having a flange and a first groove, the second coupling portion defines an opening and includes first and second ribs extending into the opening and spaced apart along a longitudinal axis of the handle, the first and second ribs define a second groove therebetween, and the damper occupies the first and second grooves, and

wherein the first coupling portion includes a first mating surface facing toward the handle, the second coupling portion includes a second mating surface facing toward the motor housing and positioned opposite the first mating surface, the first lip portion wraps over the first mating surface such that the first lip portion is positioned between the first and second mating surfaces, and the handle includes an elastomeric grip having a second lip portion that wraps over the second mating surface such that the second lip portion is positioned between the first and second mating surfaces.

2. The power tool of claim 1 , wherein the first coupling portion includes the first mating surface facing toward the handle, and wherein the first groove circumscribes the boss and is defined between the first mating surface and the flange.

3. The power tool of claim 2 , wherein the second coupling portion includes the second mating surface facing toward the motor housing and positioned opposite the first mating surface, and wherein one of the first coupling portion and the second coupling portion includes a locating rib, and the other of the first coupling portion and the second coupling portion includes a locating groove that receives the locating rib to locate the handle with respect to the motor housing.

4. The power tool of claim 1 , wherein the motor housing comprises two motor half housings, and the damper comprises two damper halves each coupled to a respective motor half housing.

5. The power tool of claim 1 , wherein the damper is overmolded to the first coupling portion.

6. The power tool of claim 1 , wherein:

the motor housing extends along a first axis;

the handle extends along a second axis perpendicular to the first axis;

the first coupling portion includes the first mating surface facing toward the handle;

the second coupling portion includes the second mating surface facing toward the motor housing and positioned opposite the first mating surface;

the damper includes a mating surface portion that extends outward in a direction transverse to the second axis; and

the mating surface portion is positioned between the first and second mating surfaces.

7. The power tool of claim 6 , further comprising a battery pack oriented along the second axis.

8. The power tool of claim 6 , wherein the flange extends outward in a radial direction transverse to the second axis.

9. The power tool of claim 8 , wherein the damper is overmolded to the boss.

10. The power tool of claim 1 , wherein the elastomeric grip includes two grip portions.

11. The power tool of claim 1 , wherein the boss has a square cross-sectional shape.

12. The power tool of claim 1 , wherein the handle includes a first handle half housing and a second handle half housing.

13. The power tool of claim 12 , wherein the first handle half housing and the second handle half housing define a recess.

14. The power tool of claim 13 , further comprising a friction wear member positioned in the recess.
