A power tool is provided including a housing including a grip portion; and a brushless direct-current (BLDC) motor at least partially disposed within the grip portion of the housing. The motor includes a stator having a rotor core, a rotor, and front and rear bearing support structures. The stator core includes a non-segmented construction with a maximum diameter of approximately smaller than or equal to 34 mm, and a ratio of a motor size (Km) constant of the motor to a length of the motor is in the range of approximately 0.39 to 0.59 (Nmm/√W)/mm. When powered by a 20V battery pack, a ratio of a maximum power output of the motor to a volume of the motor is at least approximately 0.0106 W/mm{circumflex over ( )}3.

An adjustable grinding apparatus includes a grinder having a motor and grinding disk. A grinder base houses the motor. The grinder base has at least one sidewall extending around at least a portion of the motor. An adjustable motor support includes a motor support surface positioned between the motor and the grinding disk. First, second arms are affixed to first and second ends of the motor support surface and rotatably secured to the at least one sidewall. At least one of the first, second arms has at least one slotted cutout. A locking mechanism is in communication with at least one of the first and second arms and the at least one sidewall through at least one slotted cutout. The grinder and the adjustable motor support are rotatable about the grinder base to adjust a grinding orientation of the grinder. A grinder position is fixable by tightening the locking mechanism.
