LUO KE9Pcs Quickly Changed Rotary Collet Set Clamping Nut Fits For Dremel

I've got several different size rotary tool bits, but only one tool, a Black & Decker RTX. Had a project that I needed to use some of my smaller bits, but the collet on the RTX was too large. Looked at buying a new rotary tool, but didn't want to spend the money. Saw these collets on the scroll bar and gave them a shot. They fit the RTX perfectly, were easy easy easy to install, and they covered all the different size bits I had! So great when I can get the perfect product/solution at such a great price! They've already more than paid for themselves! Really quick delivery, great price and a great product!

They don't fit in the Dremel correctly, they are too large a diameter to fit in the Dremel, but that is okay if you are willing to sand a bit off with some emery cloth or wet/dry sandpaper. I chucked them up in a 1/2 inch variable speed drill but a smaller drill would have been better. I noticed I didn't have to pinch the ends in order to hold them in, I could keep the bits in the chuck by keeping pressure on them while I was sanding, it just took a minute. The stainless steel is really brass, chrome plated and not magnetic. The brass ones may in fact be thinner because of no plating. Either way, if they are too thick to fit in the Dremel you can thin it to fit perfectly with some 80 grit emery cloth or similar. I did it with a trickle of water over a sink!

Works great.

Good selection of collets

They fit perfectly in my dremel tool. They are a lovely shiny silver. They glint in the sun.
