If you can only afford one drill at the moment, it’ll tackle most of your applications without any issue.
PROLEVEL CONCRETE PRO
Pro Pick: For heavy-duty drills, get at least 750 in. Generally speaking, as you move up that line you get more torque along with increased size. There are several classes from 12V to 18V compact and 18V heavy-duty. So how much torque do you really need? Some drills go as high as 1200 in-lbs and others fall in the low 300’s. Pro Pick: Make sure your drill has at least 2 speeds and hits 1800 RPM for it to sit at what we call a “Pro” level. You typically find more variability and control than first meets the eye. However, even our diminutive 12V single-speed Ryobi has a variable speed trigger (as do larger 18V tools). Once in a great while, you’ll even run across a 4-speed drill like the Hilti SF 10W A22 which provides lots of control for nuanced work. That second speed really fills a nice gap and delivers faster drilling in harder materials. You’ll find a few drills with three speeds. The choice, of course, depends on the material being drilled or the fastener being used. On drills and hammer drills, lower speeds deliver higher torque. Top speeds range from around 300 to 2000 RPM or more. Many drills, however, include both a Low and High RPM gear switch. Some smaller or less expensive drills have just one speed. Looking for that Pro Level Drill Speed and Control Later, supplement with a 12V model if it lightens the load and your budget allows. Pro Pick: Start with a 1/2-inch 18V drill. However, you’ll still run into tough or stubborn jobs that require 18V muscle. They are lighter, charge faster (at least for now), smaller, and less expensive. Unless you’re in production work, chances are you can perform 80–90% of your job (and tasks around the house) with a 12V tool. So how about 12V vs 18V tools? Good question! We wrestled with that question in-depth. Brushless motors are also lighter but-as you may have suspected with all these advantages-more expensive. This works as an app-based tool control and fleet management technology. But that’s not all brushless motors allow smart electronics – that is, communication between the motor and battery that maximizes performance and protects against damaging thermal overload.Ĭompanies like Milwaukee Tool have innovated around these smart electronics to create even more impressive functionality like Milwaukee One-Key. This eliminates that wear and tear and results in longer motor life. Brushless motors are electronically-commutated. This creates friction, heat, and wear on the brushes that will eventually need replacement. Brushed motors are physically-commutated, which means inside the motor there’s contact between brushes and the commutator. Regular readers will be familiar with our article on the contrast between brushed and brushless motors which we link to quite often. What to Look for on a Pro Level Drill: Brushless Motor So if you’re new to your trade, start here, but ask around to see what the other Pros you work with carry. However, electricians have different needs than general contractors. Generally speaking, this is a good list to go by for the construction industry.
