Mesee 0.5-3mm Brass Drill Chucks, Micro Electric Drill Bit Chuck Collet Mini Twist Drill Chuck Set with Allen Wrench for Rotary Tools Fits 2mm Shaft, 7Pcs/Set, 3 Set

Surprisingly high quality machining. Smooth action tightening the collets. There is a large lead-in chamfer on the smaller ID collets, not an issue for me but beware if that affects your application.

These are great. I actually bought them for the adapters to fit a much smaller drill and they work perfectly so that I don’t have to buy a Dremel. The size is perfect. The build quality is perfect. The fit is perfect. I definitely would recommend these if you don’t want to have to get a whole Dremel set and you have one of the little Corded drills and already have drill bits that you just want to use for that cordage drill. I would definitely purchase these again and buy these as a gift for a crafter who has or needs these bits I also like that they come with the little black screws to center the bit on each side each set comes with two mini screws to hold them in place

I was just amazed at how much force they can handle to be so small would buy them again for sure

I bought these and some 3mm stainless rods to make my own rotary tool extensions to get into hard-to-reach spots. They work great. The rods aren't hardenable, but as long as you keep the length reasonable, it isn't an issue.The 3mm grips a standard rotary tool shaft really well.

They fit perfectly and exceeded my expectations. They were very easy to install . Just 2 set screws to titen and the drill runs straight and true.

Bought and used this to make a small spot welder for making battery packs.

Used these for a fingernail Dremel because of fwd and reverse now my favorite dremmel

The chucks look okay at first glance, but after installing, I noticed thag they were not tapped straight so the lean and wobble. The not all of the threads for the set screws were tapped all the way through so only one side could be tightened. I can't use these for any application I planned.
