Whether you are just learning the fundamentals of simple care or are carrying on another addition to the home, a fantastic drill is essential. And when it is a cordless model, you can drill holes and drive screws with the same tool — and not have to be concerned about finding an outlet near the work to power the drill. The fantastic news: There are countless of these drills on the market. The good thing: It’s not necessarily apparent which drills you need to be considering.
For cordless drills, power is measured in voltage. Higher voltage means more torque-spinning strength to overcome resistance. Today’s higher-voltage drills have sufficient capability to bore large holes in framing timber and flooring. That’s impressive muscle. But the trade-off for electricity is fat. A typical 9.6V drill weighs 3 1/2 lbs., while an 18V model weighs up to 10 pounds. Handles Before cordless drill/drivers arrived, most drills had pistol grips, where the handle is behind the engine such as the handle of a gun. But the majority of today’s cordless models are equipped with a T-handle: The manage base flares to stop hand slippage and adapt a battery. Because the battery is centered under the weight and bulk of the engine, a T-handle provides better overall balance, particularly in heavier drills. Also, T-handle drills can often get into tighter spaces as your hand is from the way in the middle of the drill. But for heavy duty drilling and driving large bits, a pistol grip does let you apply pressure higher up — almost right behind the bit — allowing you to put more pressure on the job.
An adjustable clutch is what separates electric drills from cordless drill/drivers. The result is that the engine is still turning, but the screwdriver bit isn’t. Why does a drill need a clutch? It gives you control so you don’t strip a screw or overdrive it when it is cozy. It also helps protect the engine when a lot of resistance is met in driving a screw or tightening a bolt. The number of separate clutch settings varies based on the drill; greater drills have 24 configurations. With this many clutch configurations, you can really fine-tune the power a drill provides. Settings with the lowest amounts are for small screws, higher amounts are for larger screws. Most clutches also have a drill setting, which permits the engine to drive the bit at full power.
The cheapest drills operate in a single rate, but many have two fixed rates: 300 rpm and 800 rpm. A slide switch or trigger lets you select low or high rate. These drills are excellent for many light-duty operations.
For more refined carpentry and repair tasks, choose a drill which has the exact same two-speed switch and also a cause with variable speed control that lets you vary the rate from 0 to the top of every range. And if you do more hole drilling than screwdriving, start looking for more 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 are smaller and operate longer than standard nickel-cadmium (Nicad) batteries. NiMH batteries also pose less of a hazard when it comes to disposal than Nicads because they don’t contain any cadmium, which is highly toxic. Makita, Bosch, Hitachi and DeWalt offer NiMH batteries, along with other manufacturers will soon create these power cells also. All cordless drills include a battery charger, with recharge times that range from 15 minutes to three hours. But faster isn’t necessarily better. A contractor might rely on quick recharges, but slower recharging isn’t usually a concern in your home, especially in the event that you have two batteries. What’s more, there are drawbacks to rapid charging. A quick recharge can harm a battery by generating excess heat, unless it is a specially designed device. If you want a speedy recharge, then go with an instrument from Makita, Hitachi or Panasonic, whose”smart” chargers are equipped with temperature sensors and feedback circuitry that protect batteries. These units provide a fee in as few as nine minutes without battery harm.
Have a look at drills at home centers, imagining their weight and balance. Test vertical and horizontal drilling positions to learn how comfortable you feel. Contoured grips and rubberized cushioning on some models make them quite comfortable, even when you’re applying direct palm pressure. While you’re at it, see how easy it is to alter clutch settings and operate the keyless chuck. Home centers often discount hand tools, so be watching out for promotions. If you know the model you need, check out costs over the telephone.
Considering all the different models of drill/drivers on the market, it’s easy to buy more tool than you actually need. The solution: Purchase a drill based on how you’ll use it. It doesn’t make sense to pay $200 for a tool you’ll use only to hang pictures. Nor can it be a fantastic idea to pay $50 for a drill only to have the engine burn out after a few days of heavy work. You don’t have to drive yourself crazy trying to think up all the possible tasks you’ll have on your new tool. Have a look at the three scenarios that follow below and see where you match.
