Dewalt impact driver drivers#
Most DEWALT impact drivers are very compact, making them easier to get into tight spaces than a standard drill driver.Ī set of three bright LEDs lights up dark corners and stays on for 20 seconds after you release the trigger so you can see what you’ve been doing.īelt hooks are provided, but they’re easily removed if you find them getting in the way. IPM is an interesting figure, but of limited practical value. For torque, DEWALT quotes inch pounds (in-lbs) rather than the usual foot pounds (ft-lbs) – perhaps because the figure sounds higher! Just divide by 12 to convert from one to the other.

Speed (in rpm) tells you how fast the driver rotates, whereas torque tells you the actual rotational force applied – that’s what does the work when you’re driving long screws. You’ll want to look at speed, torque and, to a lesser extent, IPM (impacts per minute) when considering an impact driver. This offers high torque at comparatively low rpm, for work that requires delicate adjustment. With the three-speed models, you also have DEWALT’s Precision Drive. The first does provide variable speed, but it depends on trigger pressure, and it’s not easy to judge accurately. Single and three-speed models are offered. Although the 18V models offer good value, if you’re looking for maximum performance we would recommend the latter. It’s cheaper, but isn’t nearly as efficient as the brushless motor in the 20V range. We suspect the 18V models will gradually be phased out, because they use a brush motor. DEWALT impact driver featuresĪs we’ve just mentioned, there are three power options: 12, 18 or 20 volts. If you’re buying an 18- or 20-volt impact driver, 2Ah is a sensible minimum, though we would always recommend either the 4Ah or 5Ah alternatives. The best kits provide two batteries so you can carry on working – but that means extra cost. While highly rated by many owners, there are limits to how long these will run. The smallest DEWALT batteries are 1.1 Amp hour, fitted to the 12-volt impact driver. Amp hours (Ah) tells you how long that performance can be maintained. Voltage defines outright performance – with DEWALT you have a choice of 12-, 18- or 20-volt tools. However, battery performance has increased dramatically in recent years – to the extent that with their impact driver tools, DEWALT has now abandoned corded completely.ĭoes that mean there are no drawbacks? That still depends on the batteries. Cordless tools offer greater freedom, at the expense of outright power and the need to stop – all too frequently – to recharge. Cutting the cordĮver since the introduction of cordless power tools, there’s been a difficult choice between them and their and corded counterparts. It’s something of a specialist tool, but if you’ve got a lot of repetitive driving of substantial screws – let’s say you’re laying decking, for example – you’ll be glad you’ve got one.Ī quick change from the driver bit to a socket, and the same tool can also be used for tightening nuts and bolts. In addition to increased torque they also have a hammer action, which radically improves penetration. If you try driving 2-inch wood screws into a piece of 2x4 without first drilling a pilot hole, you’ll soon discover their shortcomings.Īn impact driver is designed to do that kind of job all day long. Why buy an impact driver?Ī standard drill driver will do a lot of jobs around the home and job site, but their performance is limited. If not, you might get better value buying a kit, rather than individually. If you already have other DEWALT tools and batteries, you can enjoy significant savings by buying bare tools that use compatible batteries. ‘Bare tool’ means it’s sold without a battery or charger.
