This is the easiest and potentially cheapest way to get the 3/32 bits to fit a Dremel without having to always change chucks or buy an adapter shim (that is hard to find and obtain). It also offers the ability to get REALLY small drill bits to work in a Dremel or other 1/8" (or even 3/32) chuck.

The two larger chuck work very smoothly. The smaller chucks are a little stiff. All chucks handle a range of drill bits from No. 78 to 1/8 in. I mostly use the smaller of the two large chucks. This chuck grips drill bits very securely withno slippage even in hard to drill materials like delrin, polypropylene, and brass. The larger chucks are suitable for1/4 in drills. The smaller chucks work well in a Dremel tool. I highly recommend them.

Three small springs inside the adapter attempt to hold the clamping jaws in place. On first use, one of the springs broke causing one of the clamping jaws to twist resulting in my drill bit to become lodged inside the adapter. I had to fight the adapter in order to even retrieve my drill bit.Also, the item is very low quality and any inserted bit will spin rather than be held fast.Good idea, poor execution. Returned immediately.

The chuck gripping power seems a bit lower than expected. The chucks are lightweight which is ok provided they can perform. The smallest chuck will be very handy when using tiny bits.

Now I can use my itsy bitsy drill bits.

Seems to be made well. Perfect for putting real small drill bits in larger drills and dremels. Just took about a month to get. So order way before you need them.

Great value

Happy with my purchase

The two smaller chucks have so much run-out it is impossible to drill a 1/16 hole in aluminum without breaking bits. The two larger chucks slip badly even if I tighten them with pliers - they are supposed to be hand tightened (maybe by a gorilla). I bought these to use for precision work in my mini mill and used precision collets to hold them perfectly centered but they are totally unsuitable for any kind of precision work.

Excelente, entre mis aficiones es el modelismo naval y se emplean minibrocas en donde estos broqueros son buenísimos y me permiten sujetarlas con seguridad y comodidad.
