Carpenters, craftsman, and the all around handy man need a tool that is capable of placing screws into material accurately, and reliably. Utilizing a powered drill is the most viable option because the drill provides mechanical advantages that far surpass the conventional screw driver. With the slight pull of the trigger a powered drill is capable of providing many foot pounds of torque that is capable of placing screws into various materials accurately and effectively.
By carefully analyzing the Black and Decker DR202 it is clear to see why this drill has been a consumer favorite over the years. At first glance one may be attracted to the black and red color scheme that has became the standard for Black and Decker products. The outer covering is made of a sturdy plastic along with rubber grips for added comfort and control. Other features that help to separate the Black and Decker DR202 from other powered drills on the market are the level on the back of the drill as well as a keyless chuck. Taking a closer look under the outer casing a powerful 5 Amp motor is utilized to provide adequate power for the toughest jobs.
Granted, Black and Decker has created a drill that accurately and reliably drills screws into various materials there is still room for improvement. By disassembling and reviewing the manufacture processes, material type, and function of ease individual component of the DR202 our team was able to suggest some design changes. These design changes could be implemented to keep the Black and Decker DR202 drill on the top of the competitive marketplace.
The objective of this project was to examine the Black and Decker DR202 powered drill. By disassembling, reassembling, and reviewing the inner workings of the drill our group was successfully able to grasp how the DR202 was manufactured and how to improve upon the design of the DR202.
Our group was a collaboration of five dedicated individuals whose contributions are noted below

Before Disassembly Section
The purpose of the Black and Decker DR202 was to fasten and remove screws into materials such as drywall, sheetrock, and wood. The DR202 is able to accurately and reliably place screws into various materials with the aid of the level that is provided on the drill. Drill bits can be removed by utilizing the keyless chuck. The DR202 chuck is capable of holding drill bits that fall within the range of 1–10 MM. Each bit can perform specific functions when utilized with the DR202. For example some bits are used to create holes in materials while other bits can be utilized to drive screws into materials. The DR202 is powered by 120 volts of alternating current and has the capability of rotating clock wise as well as counter clockwise.
Our group estimated the DR202 powered drill would have 30 parts some of these parts are listed below:
1 Directional Switch
5 Outer Casing
7 Power Trigger
Prior to disassembling the Black and Decker DR202 our group believed the Power drill consisted of 4 types of materials.

Guide to Writing Wiki Code
The beauty about Wiki is that if you don't know the code, you can steal it from someone's page that does. Feel free to click the "edit" links or tabs to view the code for sections or the pages respectively. Be weary about wrecking havoc on another's page. Each page can be rollbacked to a previous verison and your username is linked to all changes. Although you might think it's cool to go through and insert "MIKE RULES" throughout the page, I'm sure Dr. Lewis would not be pleased.
Here's a few tips on writing with Wiki:
