What To Check

Exact tip sizes (Phillips, square, Torx) are not itemized on DEWALT's page
Driving bits only; no drill bits in the set

The DWA2T40IR is DEWALT's 40-piece impact ready bit set: short and long FlexTorq screw bits, a socket adaptor, magnetic holders and nut drivers in a clear-lid ToughCase+. It is one of Amazon's top sellers in Screwdriver Bit Sets.

Plain bits snap or round off under an impact driver. These are made for it, which matters the first time you sink a long lag or a stack of deck screws.

The Numbers That Matter

40 pieces. Twenty-five 1 in. bits, nine 2-1/4 in. bits and one 3-1/2 in. bit, plus the holders and adaptors that make them useful. The long bits reach into recessed holes on furniture and cabinets.

15 degree flex. The FlexTorq zone gives a little under the peak hits of an impact driver instead of cracking, which is where bit life comes from.

Magnetic screw lock sleeve. It holds the screw straight on the bit, so you can start a screw with one hand while the other holds the board.

Who It Is For

Anyone with an impact driver and a list of screws to drive. It is built for tools like the one in the DEWALT DCK240C2 drill and impact driver kit. The case slips into the WORKPRO 16-inch tool bag, and the RAK magnetic wristband holds the screws while you work.

The Short Version

A bit set is what turns an impact driver into a useful tool, and the DWA2T40IR is built for that job: deck screws, cabinet hinges, battery covers on toys. The clear case makes it easy to see what walked off before a project starts. If you also need drill bits, plan on a separate set.
