Size:1 This unique, exclusive, double-duty chuck driver ensures that popular 1/4-inch and 5/16-inch magnetic hex drives are always at hands reach. The dual-sided hex socket fits over a 1/4-inch magnet-tipped, ball-detent locking hex shaft and is quickly reversed for changing sizes. Tested torque of the socket and shaft is equal to comparable one-piece single size drivers to ensure optimum screw performance. The removable, reversible socket also allows easy access for cleaning the magnet tip to eliminate any troublesome buildup of metal shavings in the hex opening. Positive engagement of hex head fasteners is never compromised. The number MSHC Reversible Hex Chuck Driver is ideal for pairing with Malco Zip-in self-piercing or Bit-Tip drill and tap metal screws.

Very useful bits in 2 popular sizes.
These are great. 2 sizes I use daily. I wish I can find the 4" & 6" versions of these bits. So glad I found these.

Almost perfect
In the hvac field and most common fasteners 1/4 and 5/16 to have both on one chuck is great. This is a 5 star item in that its quality sturdy and keep buying because i loose it before it breaks. The reason for 4 stars is that the 1/4 side is too wide to fit the head of the screw in fair amout of circumstances i run into. I modified mine by grinding down the 1/4 to alow into tight spots. And due to having to grind it down to fit my application is why it looses a star being that i believe it was designed for the hvac field. Minor flaw

great time saver
when your job primarily uses 1/4" and 5/16" retcons and screws, this is a great driver. only issue i have is, if you get it bound up against something and move on, the sleeve will pull off and either stay on the screw or fall off. i've lost one already and you can't just buy the sleeve. but overall, very handy driver and saves time vs trying to swap out drivers or trying to find where that damn 5/16" driver is hiding. probably hanging out w/ the 10mm socket.

If you do HVAC or appliance repair you need this
Saves so much time without looking for different bits. These are the two sizes that I commonly need the most. Also if you get anything stuck in the magnet it is very easy to remove unlike the normal driver bits, Highly recommend.

Easy to clean saves time can have to dig out chucks all the time
I had these before hard to find Unless there is an HVAC your house nearby. It is very nice to be able to switch your chuck at a moments notice. The main screws that i work with are 1/4 and 5/16. You can also clean out the debris pretty easy just by removing the barrel off the chuck

Super GREAT a bit expensive but the cost is forgotten with the ease of the tool
Super GREAT a bit expensive but the cost is forgotten with the ease of the tool. Now if people will stop trying them, and I can stop giving them away life will be great. I feel like the Johnnie Appleseed of driver bits.
