As a homeowner, you may not have the demand for so many individual specific tools, and that’s where the many power tool accessories may help dial in your tool needs and reduce large tool storage.
In my case, I prefer using a drill driver as much as possible for inserting screws and have long ago abandoned my 1/4-inch impact driver. I feel impact tools make a lot of annoying noise, so I avoid using them until a job truly requires their performance benefit.
But, I tend to do a fair amount of maintenance on our cars and a cordless impact wrench belongs in my tool collection, which, combined with one of these adapters, also serves as an impact driver for those building projects involving difficult fasteners.
What exactly are these adapters for?
Quickly convert a 1/2″ square impact driver to a 1/4″ hex power bit driver to hammer in those difficult fasteners. Lessen the need and storage for a dedicated 1/4-inch impact driver that may not fulfill the needs for majority of your home builder projects.
Testing of these adapters discovered the following details…
If losing the compact design of an impact driver is important, you may want to reconsider. An impact wrench already has a disadvantage with protrusion of the square anvil. Add an adapter, and you have an average of 1.6″ (40mm) longer, compared to an impact driver.
**Tool lengths will vary between manufacturers.
A few adapter complaints I’ve read:
Complaint – The 1/4″ hex quick-load mechanism is too deep, and therefore hard for short driver bits to be removed.
Complaint – Adapter is difficult to remove from impact tool compared to normal sockets.
My Response – For safety, impact sockets are designed in a way where you have to depress the spring-loaded lock pin, for both attaching and removing. A screwdriver, torx, etc. will work to depress the ball spring. Standard sockets don’t have the thru hole and just pressure fit, so they can slide on / off with greater ease.
Complaint – There is excessive wobble from the adapters on the 1/2″ anvil connection.
My Response – This issue is true, and appears to be an engineering mistake. (i) The picture below shows how any of my IR (Ingersoll Rand) impact sockets are designed with a flat seat. (ii) Both Dewalt and Milwaukee (right) seem to have copied a standard sockets seat with a tapered design, which allows the adapters to sit further back on the 1/2″ anvil. Instead of a proper fit like IR, where the locking pin pushes tight against the back wall of the pinhole, and allows zero movement, the pin sits more forward or center of the thru hole and allows 1-2mm of loose travel.
**The wobble only exists in static mode and has no effect on driving a fastener once pressure is applied.
