Impacting ratchet tool with multiple operating modes

An impact mechanism for an impact tool, the impact mechanism comprising:

• a camshaft configured to rotate about an axis in response to receiving a motor output;
• an anvil including anvil lugs;
• a first hammer mounted to the camshaft and including hammer lugs that are configured to rotationally impact the anvil lugs;
• and
• a second hammer sleeved onto the first hammer;
• wherein one of the first hammer and the second hammer includes a plurality of key portions and the other of the first hammer and the second hammer includes a plurality of keyways, each of the key portions configured to slide along a corresponding one of the keyways to allow for relative axial movement between the first hammer and the second hammer.
