Dewalt DWA2T40IR FlexTorq Screw Driving Set Review 

Thanks for taking your time to read our detailed review of the extremely popular Dewalt DWA2T40IR FlexTorq screw driving set. Please note that these bits are designed to be fitted directly into an "impact driver."

We believe that this set is very well made. It certainly fits screws better than any other types of bits out there. They are designed for professionals working at sites, but these are also an excellent set of bits to own, if you like to do DIY work or projects around the home and yard.

They come in a hard case that is tough as durable and can be easily opened and closed without having to about it braking or springing open.

Drills vs Impact Driver Bits

Some buyers do get a bit confused between the use of an impact driver and a drill when it comes to driving screws home. They are very different tools, and this is important to understand when loading bits.

  • Drills typically have keyless chucks that accept a variety of either round or hex shank bits, These bits are then held in place by twisting and tightening the chuck around the bit
  • Impact drivers have a collet that accepts 1/4-inch hex shank driver bits—to insert or release a bit you pull the collet forward.

If you haven't bought bits for an impact driver before, that is an important difference to be aware of. The bits are a little bit harder to change in an impact driver in that they need a bit more force.

It isn't a big deal, but it is just important to understand.

Who Should Buy this Dewalt Screw Driving Set?

Dewalt DWA2T40IR

Our opinion on this particular set is that if you want to own a ‘buy it for life’ type product, then this is the set of bits for you. Like most things in life you truly do get what you pay for.

If you have ever bought and used cheap driver bits, we are certain that you will have ended up extremely frustrated. The reason is that cheap driver bits break very easy, strip their heads and wobble like crazy.

These bits are more expensive than other brands but they don't break. That means a one time purchase and you never have to worry about having the right bits again.

People may buy an impact driver in addition to owning a drill. When using an impact driver for driving either screws or bolts, you should know that you can do tougher jobs. These are typically harder screwdriving jobs that would stall out a cordless drill.

For example driving longer screws into hard woods. 

Impact drivers can deliver 2-3 times more torque than a drill and is less likely to twist your wrist. With an impact driver and bits you are much less likely to strip screws.
