IIT 64510 Magnetic Bit Extensions Set, 3-Piece

I use these with a ratcheting driver set so I can get to those areas too narrow for a stubby handle since the collar on the driver is only 3/4" long. This set was less than a buck more for a single 6 inch extender. It's like getting two extenders for a buck more than one. Well, almost. The 6 inch extender is 5-7/8", the 4 is 3-15/16", the 2 is 2"(maybe 2-1/32"), to be more precise. The collar on each is almost precisely the same size, 1-5/16" (within 1/64"), but the shank is likely not uniformly set from one pack to another, so each buyer is likely to get slight variances in length of each extender. This seems true for most extenders on the market. For me, I was able to get 5-5/8" from the 4" and 2" extenders combined and 11" from all 3 extenders combined, give or take 1/32". All measurements are made without placing them in the driver. The best thing about this set over an individual extender is the ability to mix and match for different lengths. The 2 and 6 make 7.5", the 4 and 6 make 9-7/16". That's 7 different lengths from a set of 3 extenders. So if you need more than 9" for reach but less than 11" for total space, you're covered. They are also good for quick changes of hex bits with power drills (especially if using hex shank drill bits and driver bits back and forth for setting screws; much faster work). The shank ends of the extenders wobble a little in a standard hex driver just as they do in each other's collars, but that is expected from any hex bit (just more noticeable because they are longer). The magnets are good enough to hold the weight of each extender in any configuration while aiming them down and shaking vigorously, even with the wobbling, so good for standard bits too. The collars themselves are not magnetized so don't think they will retrieve lost screws, they're not designed to. I have not used them to tighten anything too much or loosen anything that was really stuck, but they are easily as capable as anything else I own in this price range. These will never replace regular screwdrivers for getting into small holes that are recessed since the collars on bit drivers are just a little too big around (3/8"), but hopefully you already knew that; better to buy long screwdriver bits for those jobs. These came coated in some kind of smelly oil like many other tools that evaporated once unpacked for a few days. Now they are like everything else in the toolbox. Would buy another set for friends/family.

I wouldn't normally think to review something so simple, but after I immediately fell in love with these, I just had to. These things are awesome. Not only are they super inexpensive (6 bucks at my time of purchase), but they are not pieces of junk. They fit super snugly in my nut driver (I am using the CRAFTSMAN CMHT65079 CM, which I also highly recommend), so there is not wiggle room at all! When inserted, it feels so locked in that it feels like it's just a permanent part of the driver. I was certain that I would be compromising a little on quality for the price, but I am super happy. Also, I love that they aren't super bulky, so when I connect them to extend the screwdriver, their width is exactly the same as the shaft on my Craftsman, so things don't get in the way and it's super slick-looking, too. I have pictures of the shortest attachment and the longest attachment installed on the Craftsman.

I bought these for my job, they are not adjustable but each one can be used in its own versatile way. The quality is good, I liked that each one was able to fit in my case I have for it so very portable size. The only thing that would make these 5 star instead of four would have been if they were magnetic.

This is exactly what I was looking for and for the least amount of money possible. As a newly single gal I have been forced to buy tools in my new home. My ex had every tool ever made, that was nice. Now I love shopping but not for tools and man stuff. These worked for what I needed and I have used them several times without fail.

These screwdriver heads aren't great. The size and weight and nice and I guess they work. But the magnetism of them is abysmal. Find a different one

This is ONLY for magnetically connecting the actual bit (like a flat head bit or a phillips head bit), not the actual screw that you are trying to screw in. It does not help with magnetically holding screws you are trying to screw in. There is not enough magnetic pull to secure the actual screw you're trying to screw in. It only has enough power to connect, for example, a flat head BIT to the "bit extender". I thought it was a "bit extender" that would hold the screw. I don't need a "magnetic bit extender". I need to buy magnetic BITS

These are just poor quality bit extenders. When insert into a Ryobi power screwdriver they wobble. They are not even close to being straight. The 2" one does not even fit into the power screwdriver. The shank is too short. It does fit into the 6" extender.On the Positive note: the bits do fit into the extenders. The magnet in the extenders works well.Could use a sleeve that allows you to hold onto while the extender turns.Don't buy these extenders. Spending extra money on ones made with some craftsmanship is well worth it.
