Abstract
A power drill can comprise a housing having a motor that includes an output member. A rotary output spindle can be journaled in the housing. A transmission can be disposed in the housing and include a first output gear and a second output gear. The transmission can selectively couple the output member to the output spindle through one of the first output gear or the second output gear for rotating the output spindle at one of a first speed or a second speed, respectively. A speed shift assembly can include a guide plate and a user engageable member. The guide plate can selectively influence movement of the first and second output gears. The user engageable member can be movable between a first speed position and a second speed position. Movement between the first and second positions can cause the second output gear to at least partially nest into the first output gear.
