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