IRWIN Magnetic Bit Holder, 3/8-Inch (4935071)

Great find on here, nice adapter that was hard to find in stores, exactly what I needed. I've got the 20v DeWalt 3/8 impact and wanted a single adapter for drill bit heads, instead of 2 or 3 piece one I was using, worked perfect and yes, magnetic as described.

Three things I want to say about this little bit holder: 1) Just to be clear, this is little tool has a hole on each end. On one end there is a hole (the hole you can't see in the photo) which is a square 3/8 inch hole designed to be snapped on to a 3/8 inch socket wrench, just like you would any socket. On the other end there is a hole (the one you CAN see in the photo). That end is designed to hold those little screwdriver type bits (like torx bits, phillips, whatever) that you would typically use in an electric drill, or an electric screwdriver. Why would you want this? Well, basically it enables you to use your socket wrench like a ratcheting screwdriver in places where a typical screwdriver is too long to work. This enables you to use your socket wrench like a right angled ratcheting screwdriver. 2) Notice that hole on the side of the bit holder. Many socket wrenches have a "quick release" feature that does two things. First, it holds your socket in place so it won't fall off. It would be tough to even pull it off if you tried, and you don't want the socket pulling off when you're working with it. Second, it allows you to take the socket off the wrench by pushing a button on the back of the wrench. It will literally fall off in your hand. In order for that quick release feature to be used with this item, you will need to line up that hole on the side with the little protrusion on the socket wrench. Many (most) sockets are designed so the quick release will work in any orientation, but on this one you must line up that hole with the protrusion on the wrench, and it works like a charm. 3) There IS a very nice magnet in this bit holder, and it holds the bits in very securely. I tried to shake a bit off, and it didn't budge. But the magnet isn't so powerful that it's hard to pull the bit out. It's perfect. I know this information is pretty basic, but when I was looking at this bit holder I wasn't completely sure what it was for, so I thought I'd provide more details for others who might be similarly unsure. Hope it helps someone.

Works as described but wish the magnet was stronger.

This small adapter allows you to use a 3/8 impact gun with 1/4inch hex bits. The magnet has an average grip so the tips don't fall out (it could be stronger) So what can I say it gets the job done I use mine everyday.

I was needing something to hold my hex bits for use with a ratchet. This works perfect and holds the bits securely. I would of prefered the 1/4 in ratchet one but the 3/8" was less. Odd but now I have what I needed and may get a second one jto leave in the truck.

This is a great tool for impact drivers. I can use my drill bits, screwdrivers bits and have no issues with it. The perfect tool for impacts. Mine has a hog ring on the end, so this tool is hard to get off, but that is nothing to worry about. A++++

Like the words of the great Todd Howard, "It just works".

Good quality, tough, but begins to rust easily

La verdad la herramienta tiene un buen diseño y calidad. Y se maneja muy bien para un técnico en aviacion

Very good had a year now
