Attention, homeowners: Don't pay another repairman until you check out this video series on simple repairs you can make yourself.
You Will Need
- Chuck size
- Battery type
- Voltage determination
- Hardware stores
- Long cord (optional)
Determine chuck size
Determine the chuck size that best suits your needs. The chuck is the part of the drill that bits and other extensions fit into. They are typically 1/4-inch, 3/8-inch, or 1/2-inch. Three-eighth-inch drills are best for having around the house; 1/4-inch drills are good for very light-duty work, but are small and have less torque; 1/2-inch drills have more torque, but are slower.
Decide to go corded or cordless
Determine whether you want a rechargeable drill or a cordless one. Cordless drills are more convenient, but they're also more expensive and have a limited run time before they have to be recharged.
Drilling holes or turning screws
Decide whether you'll do more boring or screwing. If you're doing construction around the house -- remodeling a room or constructing a deck -- you'll want a "hammer drill," which can chisel as well as drill. If your purposes are light maintenance -- tightening loose screws or minor household repairs -- all you'll need is an "electric screwdriver."
Decide on battery type
Decide on a battery type. Nickel-cadmium (NiCd) batteries are being replaced by more efficient and earth-friendly batteries, such as Lithium-ion (Li-Ion) and nickel-metal-hydride (NiMH).
Decide how much power you need
Determine your power requirements. Cordless drill power is measured in battery voltage. High-end models are available in 18 volts and more; battery power voltage also includes 6, 7.2, 9.6, 12, and 14.4 -- 12 volts is generally enough for most jobs.
Visit hardware stores
Visit hardware stores or home centers to get a feel for several models. Try different drilling positions to get a feel for comfort. Handles may be pistol-grip, T-handle, or right angle.
