Low-profile impact tools

1. An impact tool comprising:

a motor including an output shaft configured to rotate about a first axis; and

a drive train driven by the output shaft of the motor and to drive rotation of an output drive about a second axis that is non-parallel to the first axis;

wherein the drive train includes an impact mechanism comprising a hammer that rotates about a third axis to periodically deliver an impact load to an anvil, the third axis being parallel to and spaced apart from the second axis;

wherein the hammer moves axially along the third axis to deliver the impact load to the anvil;

an idler gear that engages both the anvil and the output drive;

wherein the impact load on the anvil rotates the anvil and rotates the idler gear parallel with anvil;

wherein the idler gear rotates the output drive about the second axis parallel with idler gear; and

wherein no portion of the hammer or the anvil is located above or below the output drive along the second axis.

2. The impact tool of claim 1 , wherein the second axis and the third axis are perpendicular to the first axis.

3. The impact tool of claim 1 , wherein the output drive is formed to include an opening extending entirely through the output drive along the second axis.

4. The impact tool of claim 3 , wherein the output drive comprises an interchangeable hex insert.

5. The impact tool of claim 1 , wherein no portion of the drive train is positioned adjacent the output drive along the second axis.

6. The impact tool of claim 1 , wherein an outer surface of the anvil includes gear teeth that mesh with the idler gear.

7. The impact tool of claim 6 , wherein the output drive comprises an outer ring including gear teeth that mesh with the idler gear.

8. The impact tool of claim 7 , wherein the output drive further comprises an interchangeable hex insert engaged with the outer ring.
