Question: Will these work in the 4200 with the "EZ Change" system?
Document: just what I needed to make my dremel work for me.
Make it easier to work with all kind of bits, on all my Dremell's. Don't hesitate to buy one for your kit.
Good deal. I have not used these yet but expect that they will work well for the tasks I have planned.
I bought these for very detail work on restoring bicycles and other components connect to bicycles, they have been a handy additionto my tools.
They're nice and shiny, too, which makes them more fun to work with.Word word word word word word word word.
Brought this as a spare for my Dremel tool. Have not used it yet. Before purchasing this item, make sure it will work on your particular Dremel tool by checking the specifications.
These are very good collets that I use on my Dremel tool. I have used them on many projects in my hobby shop. These work very well and last a long time.
This is very versatile and works for every need. I wouldn't probably buy this kit again though I purchased two Dremel Chuck's and they work wonderful. Don't need to keep changing the Collet's
This was a great purchase. I had gotten a bead reamer stuck in the original collet and nut assembly, and so could not use my Black and Decker rotary tool. Not only does this work, but I can use every tool I have acquired, and they all fit.
These collet nuts all work with the keyless chuck. I'm always changing from bits to cutters and back to bits on my turned pieces. Constantly changing every thing takes time, and that's really frustrating. This eliminates the frustration.
Answer: no
