Choose a product with a larger chuck diameter if you expect to routinely drill larger diameter holes. The larger the battery’s amp hours, the longer you can operate a cordless drill.įunctions: Cordless drills are always equipped with a clutch that allows the tool to drill or drive, but it may also be equipped with a hammer function that allows the tool to drill a hole in concrete or stone using a carbide-tip masonry bit.Ĭhuck size: Cordless drills are equipped with two different size chucks, 3/8 inch or ½ inch. Increase the voltage and you can drill larger diameter or deeper holes, drive larger screws or tighten a bigger nut.īattery size: This is measured in amp hours. The larger the battery/motor voltage, the heavier work these tools can do. Mechanical insight: Four things determine the work that these tools do.īattery voltage: It ranges from 8 volts all the way up to 60 volts with 12-volt and 18-volt the most common voltages. Where to use it: Use these anywhere you need to make a hole or drive a screw, set a nut or tighten a small bolt. By disengaging the drivetrain at that point, it prevents stripping the fastener head, snapping the fastener off or driving the fastener right through a piece of wood. It’s equipped with a clutch that disengages the drill’s drivetrain when the tool reaches a specified amount of torque (turning force). It’s a battery-powered hole maker and a fastener driver for screws, nuts and small bolts.
