CNBTR 0.5-3.2mm Brass Collet for Rotary Tools Electric Grinding Drill Collect Chuck Holder Pack of 10 (4.3mm Shank Dia)

No complaints, cheap, and a varied amount of sizes, seems to be universal, and really sturdy quality. Seems to be solid brass or heavy metal. Recommend!

I was looking for a small pin vice do I could use very small drill bits to drill slowly, by hand. When I saw these brass collets in such a range of inner diameters (3.2 mm, 3.0 mm, 2.4 mm, 2.0 mm, 1.8 mm, 1.5 mm, 1.2 mm, 1.0 mm, 0.8 mm and 0.5 mm) I was thrilled! These were much more diverse than the permanently shaft-mounted pin vises I was used to and at a very good price to boot! They are made to fit in the chuck of the Dremel tool I own and fit nicely. If you install the correct collet for the tool bit your using then take the chuck off the Dremel tool, you can still use the collets by hand. I'd say the outcome is the best of both worlds so these get a big two thumbs up!

These are great little collets. I'm new to using a dremel but had previously purchased very small drill bits (.75mm, etc.) and searched all over for collects to hold them, found these. They've worked great so far, i've drilled over 3300 holes for a project i'm working on. I would recommend these based on price. Quality is pretty good. Not certain on durability yet as i've only had them for a short time, but so far so good. 10/10.

I will use these with my dremel tool for wood carving.

Buenos

I like these a lot. I was surprised that I actually use one or more of them more often than I thought. Handy for those tiny drill bits that I would ordinarily use in a pin vise. I guess my only complaint is that I dropped the box and now don't know which size if which, but no matter if it fits it screws.

Good value.

I ordered these collets with the expectation that they would fit my Dremel model 270-5 Moto-tool, based on the advertised shank diameter of 4.3mm. They are larger than 4.3mm, ranging in size from 4.78mm to 4.85mm (measured using a digital caliper). They are just barely too large to fit into the Dremel chuck, which has a 4.65mm opening! Naturally, I was disappointed, and am returning them to Amazon.
