Nice Idea, Doesn't Work Too Well [Posted on 2007-07-16]
This is a really nice idea from Dremel that is supposed to make changing bits a lot faster. And that it does. Plus it is very well made. However, I stopped using it as no matter how hard you tighten it, it loosens up and the bit begins to wobble (not a good thing at 5000 rpm). Then you have to stop and retighten. So it's too much of a bother. I do not recommend this item.

I love it! [Posted on 2007-08-21]
I began using the Multipro Chuck as soon as I got it! No need to switch collets and it will hold the tiniest bit. It is just what I needed to interchange brand accessories.
Love it, love it!

Dremel chuck [Posted on 2007-08-23]
This item works great. My only question is why doesn't the manufacturer provide it as a stock item with all its tools?

its so fine [Posted on 2007-08-28]
it may vary, but mine is nicely centered, no wobble. doesn't hold quite as snug as a collet.

they got it right the second time [Posted on 2008-01-26]
In 1994 I purchased a Dremel kit and a version of this chuck was included. I was quite excited as those who have worked with the fixed-size collets know how pesky they are, especially for small drill bits.

ohmi Vibration. I contacted Dremel Manufacturing and they, in 1995, had withdrawn this chuck as it was "too heavy" and "did not run true." They were glad to send me a package of fixed collets (but, having about fifteen different Dremels -- AC and battery), I have enough collets, thank you.

Several years passed and then I saw that the adjustable chuck was again provided. I have one and will get more ... Dremel has solved the 'balance' issues which, are mighty, given the mass of this steel and speeds of 30K RPM.

Also, I am a fan of the 50-bit box sets of carbide drills. When Harbor Freight sold these at half price, $4, I bought eight boxes. However, if you've tried these, you know that using such bits on metals, even 'soft' metals, they break easily.

Using the variable chuck I devised a solution. If you have ever tried to deal with a carbide drill, broken off in a drill hole that is critical, you will mightily appreciate this ... so ... for $9.95, check or Paypal, I'll provide instructions and 2 additional components that virtually eliminate breakage.

And, if you haven't tried such a drill, for $12.95 I will send the instructions, kit, and 3 carbide drills for you to try. Quite honestly, if you have not had the delight of using a carbide to drill, say, medium-hard steel, or even a printed circuit board, you will be very pleased.
