Whether you’re just learning the basics of simple care or are carrying on another improvement to the house, a good drill is essential. And if it is a cordless version, you can drill holes and drive screws with the same tool — and not have to worry about finding an outlet close to the work to power the drill. The good news: You can find hundreds of those drills on the market. The good thing: It’s not always apparent which drills you should be considering.
Electricity, Handles, Clutch
For cordless drills, power is measured in battery voltage. Higher voltage means more torque-spinning power to conquer resistance. Over the previous ten years, top-end voltage has risen from 9.6 to 18V, but the range of models comprise 6, 6, 7.2, 9.6, 12, 14.4 and 18V. Now’s higher-voltage drills have enough capability to bore large holes in framing timber and flooring. That is impressive muscle. But the trade-off for electricity is weight. Handles Before cordless drill/drivers came, most drills needed pistol grips, in which the handle is supporting the motor like the handle of a gun. But the majority of today’s cordless models are equipped with a T-handle: The handle base flares to prevent hand slippage and accommodate a battery. Since the battery is centered under the bulk and weight of the motor, a T-handle provides better overall equilibrium, particularly in thicker drills. Additionally, T-handle drills may often get into tighter spaces as your hand is out of the way in the center of the drill. But for heavy duty drilling and driving large screws, a pistol grip does let you apply pressure higher up — almost directly behind the bit — letting you put more pressure on the job.
An adjustable clutch is the thing that separates electric drills from cordless drill/drivers. Situated just behind the chuck, the clutch disengages the drive shaft of the drill, which makes a clicking noise, when a preset degree of resistance is attained. The result is that the motor is still turning, but the screwdriver bit isn’t. Why does a drill need a clutch? It provides you control so that you don’t strip a twist or overdrive it once it is cozy. Additionally, it can help protect the motor when a lot of resistance is met in driving a twist thread or tightening a bolt. The number of separate clutch settings varies depending on the drill; greater drills have at least 24 settings. With this many clutch settings, you can really fine-tune the energy a drill provides. Settings using the lowest amounts are for smaller screws, higher amounts are for larger screws. Many clutches also have a drill setting, which allows the motor to push the little at full power.
The cheapest drills run in a single rate, but many have two fixed speeds: 300 rpm and 800 rpm. A slide switch or trigger enables you to select low or high rate. These drills are ideal for many light-duty operations. The minimal rate is for driving screws, the higher speed for drilling holes.
For more elegant carpentry and repair tasks, choose a drill that has the exact same two-speed switch plus also a trigger with variable speed control that lets you change the rate from 0 to the top of every range. And if you do much more hole drilling than screwdriving, start looking for greater rate — 1,000 rpm or greater — in the top end.
Batteries and Chargers
Nickel-metal-hydride (NiMH) batteries represent the most recent breakthrough in batteries. They’re smaller and run longer than regular nickel-cadmium (Nicad) batteries. NiMH batteries also pose less of a danger when it comes to disposal than Nicads because they don’t contain any cadmium, which is highly hazardous. Makita, Bosch, Hitachi and DeWalt offer NiMH batteries, and other producers will soon produce these power cells too. All cordless drills include a battery charger, with recharge intervals ranging from 15 minutes to 3 hours. But faster isn’t necessarily better. A contractor may rely on quick recharges, but slower recharging isn’t typically a concern in your home, especially if you’ve got two batteries. What is more, there are drawbacks to rapid charging. A quick recharge can harm a battery by generating excessive heat, unless it is a specially designed unit. If you want a speedy recharge, go using an instrument from Makita, Hitachi or Panasonic, whose”smart” chargers are equipped with temperature sensors and feedback circuitry that protect batteries. These components provide a charge in as little as nine minutes without battery harm.
Have a look at drills in home facilities, imagining their weight and balance. Try vertical and horizontal drilling positions to see how comfortable you feel. Contoured grips and rubberized cushioning on some models make them quite comfortable, even when you’re employing direct hands on pressure. Home facilities often dismiss hand tools, so be watching out for promotions. If you know the version you want, check out costs over the phone.
Considering all the different models of drill/drivers available on the market, it’s simple to purchase more tool than you actually need. The solution: Purchase a drill based on how you will use it. It will not make sense to pay $200 to get a tool you’ll use only to hang pictures. Nor is it a good idea to cover $50 to get a drill only to have the motor burn out after a couple of days of heavy work. You don’t have to drive yourself mad trying to think of all the possible tasks you are going to have on your new tool. Look at the 3 scenarios that follow below and see where you fit in.
