I was looking into getting this ratchet for my Craftsman set to replace my raised panel one. When I look up the part number, CMMT86723, it shows that it's 72T rather than the 90T you received. The Craftsman website lists as a 72T also...
I have one that I got used off of Ebay. Worked great for installing a window. I can run it with the few Craftsman batteries I have or my PC batteries with an adapter I bought off of Amazon.
I have two of these (one for house, one for garage) in Black and Decker. My PC batteries fit them after I cut the appropriate notch in them. I also have a B&D stick vacuum that also uses PC batteries.
I use my band file pretty much where I would use a hand file, wood and/or metal. It's just that much faster. It also give a lot better access to crevices that you can't reach with a hand file. I used it today to clean up mig weld boogers I got because there was painted steel involved.
I've used my PC version of the band file more than I though I would. So far for I've used it on both metal and wood and not been disappointed. It seems to last a long time on even smaller 2ah batteries.
I've had the Porter Cable equivalent of this gun for few years now. The ring was super tight at first on a few of my impact sockets but not all of them. I found that my Astro nanos were fine from the get go. It was extensions that I had the most trouble with if I remember correctly. All is good now.
I was using one of the wheels tonight and also noticed they look quite a bit alike. I'll check the packaging next time I'm at Menards for country of origin. I'm always amazed when using these how something made of plastic is so affective at paint removal.
Looking to buy the Pferd 43740168. Where did you purchase yours? As a side note, I've used the Performax brand from Menards. The tool works pretty good. I would imagine that Pferd would be a step up in quality and, or course, price...
