What to Look For in a Cordless Drill

1. Chuck jaws: Maximum capacity on most drills is 3/8 inches. Some 14.4 and 18V drills can handle 1/2-inch-diameter bits.
2. Clutch: More settings give you greater control of the depth screws are driven.
3. Speed-range switch: High is for drilling; low is for driving screws. Look for the widest range between them.
4. Forward/reverse switch: Should be easy to operate with your thumb and trigger finger.
5. Hand grip: Texture and contour should aid your grip; try out the grip before you buy.
6. Voltage: More voltage means more power but also added weight.
7. Battery: Two are better than one. New NiMH batteries offer some advantages.
8. Trigger: Make sure your index finger fits around it comfortably when gripping drill. Variable speed offers the greatest control.
9. Keyless chuck: Hand-turn it to open and close the chuck jaws.
