Impaktor TriTorsion Ringmagnet Bit Holder
6000 10x4's can't be bad!!
This bit holder is expensive but massively outlasted all others i have used.used with 18v makita impact driver besides the 6000 10x4's into 9x2 timber and the 6in screws the magnet comfortably holds solid it's also done around 400 joist hangers with 20 1-3/4 screws in each finally wearing out.
HIGHLY RECOMMENDED AND AM ON MY 3RD. I HONESTLY DON'T BUY ANYTHING ELSE.
Might be pricey for the DIYer but if you're a heavy user you can't go wrong with this

Good Mainly 4 Impact Drivers?
This is one of the most expensive bit holders available, so is it worth paying the premium? I've found quite a few pros & cons which may not be entirely obvious, particularly if you haven't had a chance yet to handle this product....
Firstly, the holder is very solidly engineered. So much so, though, that it is quite heavy compared to most other holders of a similar length. Not an issue when used on big power tools, but might become a factor on compact units & hand tools/ drivers.
The bit can be a little tricky to grip & remove from the holder because 25mm bits only stick out of the holder by about 11mm, & the magnet which holds it is quite strong. But if you use a longer, 50mm bit, the 2nd magnet, a ring magnet which is intended to hold the fastener/ screw in place, can't be used because it only extends 10mm & wouldn't reach the screw head. Also, it is quite hard to see where the bit is when, say, trying to manoeuvre it into position onto a screw already in a wall, because the holder is quite wide & it obscures the view of the (only) 11mm of bit which sticks out.
The advantage of this holder using a ring magnet system are that it can hold larger screw heads than holders which use a system with a sleeve that slides, because it only hangs on to the outer head of the screw, & doesn't have to slide over it. It also means the screw sits nice & squarely on the holder. The downside of the ring magnet system are that you usually either need to use your 2nd hand to steady the screw when first driving it in, or need a pilot hole, because it often doesn't hold the screw strongly enough to prevent it from falling off.
Thus overall, I'd probably say not to get this holder if you only do lighter-duty jobs, & go for something cheaper, thinner & lighter etc, & possibly with a sliding sleeve. But for the jobs for which this has mainly been designed, heavy duty fastening using an impact driver, it is probably money well spent.
I still have 2 questions regarding this tool, though... Will repeated concussion from the impact driver eventually weaken the magnetism? Only time will tell. Also, this TriTorsion holder, in combination with using TriTorsion bits (which aren't strictly necessary) are designed to gives maximum absorption of the stress-inducing blows from an impact driver. Though I do wonder, then, what was the point of using an impact driver in the first place?!

Does the job well
Just decided to write this as I read a review above that said that the magnet would not hold the screws in place. The sleeve needs to be slid forward for the magent to work, when it is slid forward it holds the screws very well.
Bit expensive but hopefully it will last well with my Makita impact driver, only put in a couple of hundred screws so far.
