RotoZip CN1 Replacement Collet and Nut Kit,Silver

works like original

After looking on Amazon for days and days, and reading another reviewer's post, the RotoZip Collet is the same size the DeWalt 660 uses. Unfortunately, the Nut doesn't work due to it's rounded head and elongated size. You're basically getting 3 Collets for the price of one DeWalt Collet.

These work all right, but I have a lot of trouble with the colic sticking hard to get out if you don’t use them very often they’re all right

Like many of you, I came here looking for collet sizes compatible with the DeWalt DW660… because, while DeWalt does sell a 5/32" collet, it costs three times as much as this whole kit. And why? They are mostly compatible. The collets aren't identical, but they have the same length and the same outer diameter (~8.9mm). They are interchangeable from what I can tell, which is to say the RotoZip collets work fine in the DeWalt tool. I'm not sure why the DeWalt collet is machined to a slightly smaller diameter at the ends. The nuts have the same hex size and the same threads, but the RotoZip nut is a bit longer and the DeWalt nut has the corners of the hex nut turned off for part of the length to accommodate their chuck system. Thus, while a DeWalt nut would likely work on a RotoZip, the RotoZip nut does not fit on the DeWalt chuck, though it could be easily modified to do so with a lathe, or even a file assuming you don't need it to be pretty. The RotoZip components are made in USA, which is nice. Keep up the good work Bosch Corp.

I have used this with my drywall cutter and it works great. It's study and hold the bits very well.

Perfect. Figures brand new tool doesnt come with ALL arbor sizes.

Know what is less than great? Having a specialty tool that would be perfect for a particular project and finding that you're missing the smallest possible piece. A piece that, when absent, renders the tool completely useless. I could Roto all day but could not Zip without actually having a bit in place. Enter this collet. This solved my Zipping woes and now I have a tool that will be functional when called upon in the future.

Perfect fit. Works exactly as advertised

Fit as described

All good

I bought this having lost the collets for my Dewalt DCS551, and also wanting a 5/32 collet that didn’t come with the Dewalt to allow for the bit in between the light 1/8 and the more substantial 1/4. Exactly the same size as the original collets and the nut also fits albeit is slightly different in size to the original.

Buena calidad
