What is the difference between these two tools?

What is the difference between a DEWALT 18-Volt 1/2" Cordless Compact Drill/Driver and a DEWALT 18-Volt 1/4" Cordless Impact Driver? Does the first tool switch between a drill and a driver?

    the 1/2 inch refers to the chuck capacity

    and the 1/4 inch is also

    the 1/2 inch will take up to a 1/2 drill bit the 1/4 will only take a 1/4 inch bit

    get the 1/2 size

    The drill driver is a changeable option

    you switch to either one

    First tool is a drill or screwdriver tool that will hold up to a 1/2 inch diameter bit.

    Second tool is a 1/4 inch square drive impact wrench it will not drill or drive screws it is used with a socket set to remove nuts and bolts.

    A drill driver is a common, multi-purpose drill, mostly used for drilling holes; it can also drive screws. It has a clutch that slips when encountering resistence to avoid over-driving a screw.

    An impact driver is mostly used for driving screws; it can also drill holes. It can automatically adjust torque per encountered resistence and is prefered when driving large numbers of screws.

    A drill/driver is used to drill holes and tighten/loosen screws.

    An impact driver is used exclusively to tighten/loosen screws. An impact driver is better for this because it reduces the risk of twisting the head off a screw, as a drill/driver could. It also allows more precise tightening of screws to a specific torque.
