No tool box should be without a power drill. The versatility of the power drill is one of its most attractive qualities. Even though the corded power drill is losing popularity to its cordless counterpart, corded tools cost less and deliver more torque. Matched with the correct drill bits and accessories, the power drill can be the most useful tool you own.
Besides the conventional electric power drill, the drill/driver looks like an average power drill but is used to drive screws. The hammer drill which is a demolition-type tool is used for drilling concrete. The Home Depot carries a wide selection of power drills from consumer to professional models as well as all the accessories you will need for your projects.
Before selecting a power drill, consider:
1. What type of materials will you be drilling into? Harder materials require a more powerful drill.
2. How often will you be using this drill? A standard duty drill is usually sufficient for routine home
Other points to consider:Drill Size/Chuck Capacity -
The size of the chuck determines the maximum drill bit diameter allowance for that drill. The most popular is 3/8” diameter; lightweight-use capacity is 1/4" while heavy-duty capacity uses a 1/2" diameter.
Speed and Power -
Revolutions Per Minute (RPM) determines the speed of the drill. The higher the RPM, the lower the torque delivered. Amperage equals power. A lower amperage power drill may be suitable for house hold use or occasional shop use. A higher amperage model will deliver more power and is better suited for heavy-duty or professional use. Variable Speed -
This is a desirable feature on a power tool. A variable speed motor has multiple speed settings that use a single switch.
Reverse Mode -
Most drills manufactured today have a reverse action switch. This is convenient when removing screws or backing out when boring holes.
Keyless chucks offer the convenience of quick bit change operation; keyed chucks offer a better bit grip for larger drills.
The handle or grip should be comfortable to hold. The weight of the drill is also a factor-- since a heavy drill will cause your hand to fatigue faster.

Always exercise caution when using power tools. Follow the manufacturer's instructions for proper use; use tools for their intended purpose. Depending upon the job or project, wear safety equipment including eye and respiratory protection.
