A multi-tool (100) includes a power head (120) including a power head housing (122) having a handle (124) operably coupled thereto, a tool attachment (106, 108, 110) configured to perform a work function, the tool attachment (106, 108, 110) being alternately separable from and operably coupled to the power head (120), a motor (140) disposed in the power head housing (122), a battery (130) configured to be operably coupled to the motor (140) to selectively power the motor (140), a drive provider portion (300) disposed at the power head (120), and a drive receiver portion (320) disposed at the tool attachment (106, 108, 110). The drive provider portion (300) includes a driving portion (302) of a shaft (150) operably coupled to the motor (140), and the drive receiver portion (320) includes a driven portion (322) of the shaft (150). The driving portion (302), the drive receiver portion (320), and the motor (140) share a common axis (148). The power head (120) receives the battery (130) at an opposite end of the power head housing (122) relative to an end of the power head housing (122) at which the motor (140) is located, and the handle (124) extends from a first portion of the power head housing (122) above the motor (140) to a second portion of the power head housing (122) above the battery (130).
