EyourlifeUniversal 6.5mm Hanging Grinding Chuck Flex Shaft Key Drill Chuck Handle Handpiece Accessory for Rotary Tool Hanging Grinder Carver

I have an old Harbor Freight Chicago Electric 1/4 HP Motor with a flexible shaft. so I changed the handle and it fit in perfectly. HF shaft handles chuck too small none 1/4". Eyourlife Flexible Shaft Grinder Handle have 1/4" chuck perfect for work Carbide Burr or sander (1/4" shank). Test running is good. thumb up.

Working well so far at a fifth the price of the big name brand option. Fits on my Foredom flex shaft but you do sorta need to push a bit harder to get it to snap on there, it's not quite easy as a Foredom hand piece. At first I thought it would not fit bit I fidgeted more with it and got it on. Like another guy said, it got a bit hot in use at first but seems to be getting better. It's also slightly more noisy. The key they use is slightly different and Foredom keys are not very compatible but this key actually is easier to use than the Foredom setup, convenient if you change bits a lot like I do. This key grips better and doesn't fall off as easily. It does come with a key but you only get the one so don't lose it, although I think I could scrape by with a Foredom key in a pinch.

I bought this originally for my Harbor Freight flex tool and it works great, no real issues. But now I have just upgraded my tool to a Foredom flex tool. But this does not fit my new foredom in any way. So now I have to find a handpiece for the foredom; yes they are both key type flexshafts. I did have some issues with it getting hot but after using it for a few hours it no longer gets hot.

I am very happy with this item. I have a Harbor Freight rotary tool. The chuck that comes with it does not fit 1/4 in bits. This item is a great solution for those larger bits. Easy to use and a great price. I would recommend this item.

Don't think there's a day goes by if I'm out in the Cave sooner or later I'm gonna hit the power tools. Specifically this new hand piece and really like the molded key handle, makes changing bits alot easier.The hand piece it self is not much different than my original other than is 1 is gold in color which I liked .Vibration I'm not 100% sure about because I'm fairly new with this system so what's normal and what's not I need to look that up, both of em seem to have a fair amount of vibration.I'd buy it again and happy with the 1 I ordered.I'd do a quick change head next time...FYIWell here's just a quick update.I stand behind my orginal comment, (up to the Jan update) butAs u can see from pictures it broke from the screw in plastic piece.When I looked it up the purchase date it was just out of warranty so doubt if any will happen naturally. Another concerning part was not being able to contact seller (Eyourlife Store) so idk.When you go to the store this isn't even on the list I saw as far as products. Everything that "was" shown on their website that was listed/marked was unavailable !Just something ya mite want to keep in mind. Greatful it wasn't a high dollar item.As part of the Jan update, I personally would not be purchasing another one.FYI

the size of bits that can be used

Small enough to be used by small hands. Handy addition to hand pieces.

When you search for Foredom head this pops up. The area where it attaches to the flex shaft is too small and it won't fit over the shaft. If you're buying for a Foredom don't waste your money. And it's kind of poorly made, it has an uneven spin and clinics when you turn it. Just a bad buy especially for something as strong/powerful as a Foredom. Motor has too many rpms for that head. I'm returning it.
