Dewalt MaxFit 30 Piece Screw Driving Set – #THD – ProSpective

Dewalt Impact Bits

For years DeWalt has been making really good driver bits.  They have an exact fit in the different fasteners and are pretty durable.  Instead of sitting back and enjoying the success they have pushed ahead and improved upon them in a few areas.

Why We Need Them

Impact drivers are much harder on bits than drills because they work differently from drills to deliver higher torque in a smaller package.  In a drill the torque is constant and smooth.  With an impact driver there is a rotating hammer which impacts an anvil thousands of times per second delivering higher torque.  That torque is not smooth.  That hammer can be very destructive to bits in just a few seconds.

Because of this we need bits with different characteristics in different zones.  We need the tips to be hard so they last a long time without wearing out.  However, harder steel can be brittle.  If the entire shaft is hard it will most likely break in short order.

Impact rated bits can be made in a few different ways.  DeWalt manufacturers most of their impact rated bits with a torsion zone.  That means they have a normal 1/4″ hex shaft where the bit meets the impact driver and a slimmer more flexible area that is made to twist slightly to absorb some of the impact energy from the hammer mechanism.  It may seem strange that a slimmer shaft would make the bits more durable but it works very well.

This 30 pc. set is perfect for 99% of all my driving needs.  I prefer to use Torx head screws when I can.  It includes T 20 and 25 in both 2″ and insert tip sizes.  It also has a good mix of Phillips and Robertson in both lengths as well as 1/4″ and 5/16″ nut drivers.

Two nice features of this set are the sleeved bit extension and the 10x magnetic screw lock.  The 10x means it is 10 times stronger than regular magnets.  It really helps keeping the screw straight and definitely reduces screw drops even if you cam out of the screw head.

For the money you may find a different configuration that works better for you.  For my needs this is as close to ideal as it gets for a smaller set.  You can find these at your local Home Depot or click here to buy online  At The Home Depot

  1. Thanks for the review.
    Question was there an old set? If so what’s the new model number?

    I am not a fan of the insert bits. Is there a well rounded set that does not have the insert bits that you could recommend?
    Cheers
