I was disappointed that the sleeve was made of plastic. I thought it was a stainless steel or aluminum sleeve which is what it looks like in the pics. Needless to say it has already broken on the top of the sleeve. I can't blame the seller for this although the description doesn't say that it's plastic. Typically Dewalt makes good products, but this is garbage. I don't know why Dewalt would make a plastic guide sleeve for a bit holder other than the fact that it breaks sooner than expected and you'll have to buy a new one. Like I said this is not the seller's fault, but they need to mention that it is plastic in the description. The pics are from only one day of use. I don't see it lasting a week.
