Exactly what I needed to use 5/32" rotozip bits with my M18 cut out tool **Q: Will this work for a DeWalt DCS551D2?** A: The DeWalt has a quick change collette. For this to work it seems the entire quick change system will need to be removed, or at least that is what it appears like from the photos of the DeWalt tool that I can see. You should compare these with the actual DeWalt items to be sure. **Q: Will it fit dewalt dw660?** A: Yes, bought this for the collets, they fit the dewalt DW660. The nut will not fit the 660 but the 3 collets will **Q: Will this work on chicago cut out tool #42831 ? I need 1/4 & 1/8 collets.** A: While this kit includes a 1/4" and 1/8" along with a 5/32" collet they are recommended and tested for use with a RotoZip tool. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect replacement for Dewalt DCS551 *by I***1 on 1 February 2023* 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.
