How to Use a Bosch Impact Drill as a Screw Gun
Bosch variable speed drills can double as a power screw gun by using a screwdriver bit. This lets you buy one tool and use it for two purposes. Bosch impact drills now are supplied with lithium-ion batteries, which allow for minimum self discharge and no memory effect. That means you can put the screwdriver bit and a battery in your drill, leave the drill for a period, and when you come back to it, you're ready to drive a screw.
