I had to buy this as I have no idea what happened to the original I had with the saw. Now that I've bought this one I'm sure it will turn up. I don't know what the other reviewers are complaining about. I have a Dewalt DW3278 saw and it fits perfectly. This is definitely an OEM part. Solid and well made, I suspect some people took a chance and didn't pass. In this case just send it back? Finally, if you have a Dewalt Model DW3278 Circular Saw, this is definitely the part and it will fit easily. Because of this and the high quality of the part, I can recommend it without hesitation.
