Use for 1/4" to 4 mm Driver Adapter

I received my I Fix It Pro Tech Toolkit today and in the driver set there is the 1/4" to 4 mm Driver Adapter and was wondering what it is used for?

It's super useful if you're like me and you have a 1/4 inch power screwdriver and you want to use the 4 mm precision bits that come in the kit.

but its not magnetic so arent the bit going to fall off ?

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

Both adapters are able to hold the bits in place so they won't fall out. However if you want it to be magnetic, you'll want the older (grey) tech toolkit. The older kit comes with a magnet built into the adapter. The newer (black) pro tech toolkit did away with the magnet and comes with a friction fit adapter.

Just don't use it with a power hammer driver like I did. I ripped my 1/4 to 4mm adapter clean in half.

How do I order a replacement 1/4 to 4 mm Adapter

Also, the new design of the 1/4” to 4mm adapter is shallower than previous generations. i just took one to lowes and tried it in all the 1/4’ drill/drivers from DeWalt, Milwaukee, etc., etc.. and they no longer go in far enough to engage the retaining ring inside the bit holder. they shortened the 1/4” section and elongated the 4mm section and the flange prevents full seating… gonna swap my repair depot techs to the Wiha 75802 bit adapter so we can continue repairs…

Love this, AND… I wish there was a similar adapter to allow me to use my iFixit toolbits in my Klein Tools 32614 driver.

My adapter doesn't hold the bits since day one.

@zephyro - Contact the iFixit store to get a replacement adapter.

I thought my adapter was faulty as per the comment by Magnus G - it just took a little more pressure to insert the bit and obtain a secure friction fit. If anyone else is having that problem I suggest trying to insert the bits into the adapter with a bit more force.

I've spent too much money on cheap toolkits and so far love this one - I think I'm done spending money on electronic toolkits as this one looks like a keeper!!!

Don is right?! You really need to push to get the bits in, but that also means they don't come out easily either which is a plus, as many friction lock bits will come out when torqued on a bit
