While it’s certainly not necessary to purchase all the basic tools at once, a kit can provide cost savings over purchasing each tool singly. We especially like the DeWalt 20V MAX Lithium Ion 5-Tool Combo Kit.
The DeWalt 20V Max Cordless Tool Kit comes with a hammer drill with patented 3-speed all-metal transmission and 1/2-inch self-tightening chuck; a reciprocating saw with key-less blade clamp that allows for quick blade change; a 1/4-inch impact driver featuring 3 LED lights with 20 second delay to provide visibility; a 20V Max LED work light that delivers 110 lumens of light output; and a circular saw with 6-1/2-inch carbide blade that can cut 2-by-4’s at a 45-degrees angle.
