Group 1 - Black & Decker Drill

Executive Summary

The Black & Decker® DR202 3/8” Variable Speed/Reversible Drill is a must-have tool for almost any project. This six-pound power tool is light enough to be used for the everyday 'do it yourself' tasks while the five-amp motor is powerful enough for professional carpentry and construction jobs.

The main purpose of the DR202 is to drive and remove screws, and drill holes through various materials such as dry wall, steel, soft and hard woods, and plastics. It operates by taking electrical energy supplied by a standard household power outlet which it converts to rotational energy used within the motor. The rotational energy is transferred to mechanical energy, moving the gears within the motor, which supplies the torque to move the bit. It has variable speed: the farther the trigger is depressed, the higher the speed of the drill. The drill can also be locked for continuous use by squeezing the trigger while pushing in on the trigger lock mechanism. Additionally, the drill has a 8’ electrical cord with a two-prong plug. It has a direction reverse switch: push the switch to the right for forward rotation (clockwise rotation), push the switch to the left for reverse rotation (counterclockwise). The drill has a fifteen-position keyless chuck and a convenient bit holder located on top of the drill.
