DEWALT DWA2T40IR 40-piece FlexTorq Impact Ready bit set delivers CNC-machined precision, cam-out reduction, and magnetic sleeve support for impact driver jobs.
Categories : tools
SKU : WOR-TOO-004
The DEWALT DWA2T40IR is a 40-piece Impact Ready screwdriver bit set built for anyone who uses a cordless impact driver on the job or around the house. It pairs CNC-machined bit tips with the patented FlexTorq Zone, a torsion section that flexes up to 15 degrees to absorb torque spikes in hard joints. That means fewer stripped screws, less cam-out, and a set that keeps working on high-torque fasteners.
The FlexTorq Zone is the defining feature here. When an impact driver hammers up to thousands of impacts per minute, a standard bit can twist and break. The FlexTorq Zone flexes with that force, transferring more torque into the fastener and less into the bit. Each tip is CNC-machined for a precise fit, so it engages the screw recess more completely and reduces the chance of stripping or cam-out.
The 40-piece assortment covers the fastener profiles you’ll meet in HVAC, electrical, plumbing, carpentry, and maintenance work. Bits range from short to extra-long, and the included 10X Magnetic Screw Lock Sleeve fits 2-inch and longer bits to hold screws steady and minimize wobble.
The clear-lid storage case uses a patented bit-bar layout that lets you pop bits out with your thumb and put each one back exactly where it belongs. The clip latch keeps the lid secure, and the compact case fits inside DEWALT ToughCase+ small and medium cases (sold separately) for even better organization on the van or jobsite.
Whether you’re roughing in a new build, doing maintenance, or running a weekend project, this DEWALT bit set gives you impact-rated durability and a convenient storage system for one price.
Impact-rated FlexTorq design flexes up to 15° to manage torque spikes and extend bit life.
CNC-machined tips seat securely in screw heads, reducing cam-out and stripped fasteners.
10X Magnetic Screw Lock Sleeve holds longer bits steady, less wobble and fewer drops.
40-bit assortment covers common fastener profiles for HVAC, electrical, plumbing, carpentry.
Clear-lid storage case with bit-bar system keeps bits organized and easy to grab.

Impact drivers produce sudden, high-torque pulses. Standard bits twist at the tip and eventually snap. The FlexTorq Zone in these DEWALT bits is a specially engineered torsion zone that absorbs the shock by flexing up to 15 degrees. That flex keeps torque flowing into the fastener while reducing stress on the bit tip. You get a bit that lasts longer and far less chance of rounding out screw heads.
The set includes a mix of common profiles—Phillips, slotted, and Torx—plus the magnetic sleeve. For deck screws, drywall, and self-tapping fasteners, choose a bit that fits snugly and use the sleeve when driving longer screws to stop them from wobbling. For high-torque structural work, the impact-ready FlexTorq bits excel.
The bit-bar design lets you see every bit at a glance and remove it with one hand. When you’re on a ladder or tucked into a tight spot, that saves time. The case’s clear lid also makes it easy to check that you have the bit you need before opening the latch.
Yes, the DWA2T40IR bits work in standard drill/drivers, but they are specifically reinforced for high-torque impact drivers.
It slides over 2-inch or longer bits to hold screws firmly on the bit and reduces wobble, which helps prevent dropped fasteners and stripped heads.
Yes, the small bulk storage size fits inside DEWALT small and medium ToughCase+ cases (sold separately).
Yes, you can buy individual DEWALT Impact Ready bits, but the 40-piece set offers a convenient assortment at a better value.







Great bits, no stripping.
The case is nice. Bits hold up well in my impact. A bit pricey.
These bits are excellent. I use them daily for electrical work. They seat snugly and don't strip screws. The case keeps them organized. Great quality.
Fine for the price. The magnetic sleeve is a plus.
So durable! I've snapped cheap bits before, these don't break. Highly recommend.
I've been in the trades 50 years. These are the best bits I've used. They fit tight and last.
I wish it included more common sizes in duplicate. The ones you use most wear out eventually. But the case is sturdy.
