9Pcs 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!

Using a Dremel is always great fun, but not so much the different size collets needed to support the bit shafts. Having these collets all in one place and all different sizes makes it so much easier to work. Before, if I used a buffing bit, I would have to tape the shaft to make it fit. Gratefully, now that's no longer the case. Great set for the money.

Works great

A few reviews said they didn't fit on their Dremel brand rotary tool, but they work just fine on mine. Much cheaper than the name brand ones too. Held my smaller diameter bits in place.

fits both my 3000 and 4000 and gives me the ability to use a wide variety of bits.

I'm happy with them. They fit my Dremel stylo, hold the bits as they should and are far cheaper than genuine Dremel collets.

I should have realized that these parts, coming from China, would be a lesser quality than the original Dremel parts. They do fit, but are obviously lighter in weight, strongly suggesting that they are made from a lesser quality or lesser processed steel. They simply feel shoddy. Since they will be used on a high-speed Dremel too, I have doubts that they will be able to withstand any hard or rugged use. However, only time will tell as to their overall quality and longevity. Remember, you get what you pay for.
