Abstract
An impact tool includes a housing, a motor supported within the housing, an anvil extending from the housing, and a drive assembly configured to convert a continuous rotational input from the motor to intermittent applications of torque to the anvil. The anvil includes a body rotatable about a longitudinal axis, a driving end portion configured to receive a tool element over a distal end thereof, and a bore extending through the driving end portion of the anvil in a direction transverse to the longitudinal axis. The driving end portion includes a groove located between the bore and the distal end. The groove includes a curved portion converging toward the distal end and is configured to receive a friction ring such that the friction ring follows a contour of the groove.
