Review on 🔧 Enhance Your Grinder with Yakamoz Converter Attachment Accessories by Evan Haynes

I would give this one five stars if the first one worked. Had to order a second one due to poor quality control. The Yakamoz square converter fits both of my grinders, but you have to play around with the square cord that goes into the collet so it doesn't press against the top of the tool when you tighten the nut. I had to order two because when I removed the collet nut (or collet chuck for you purists) not only was a socket wrench required, but it was also impossible to unscrew the threads back in a straight line. The cartridge was very light aluminum and had a burr on the bottom which indicated to me that the machine had probably over-tightened it and damaged both the nut and the threads. I tried to find a die to re-cut the collet holder as everything worked except nothing could be screwed to tighten the collet to the cable that powers the tool. I figured since it turned out to be universal, I might find a die and cut the threads. HA! My thread gauge showed 40 threads per inch, but it was 7mm in diameter, so the closest metric die I could find had a thread pitch of 7mm by 0.75, which was still too large. I called all the local Tap and Die vendors and no one had or had anyone who knew of such an animal. Since the price was less than 1/2 the Dremel contra-angle I tried a different one and apart from the fragile cartridge it seemed just as durable as the Dremel if not better. I would recommend using collets and chucks from your other grinders as the Yakamoz is really light, but I've run it a few times and it seems to work fine. All my Dremel and Milwaukee tools work great with it and I love the fact that there is an adjustment ring on the bottom where it screws onto the end of the tool. So if you need to change the angle, just flip the ring back. rotate slightly, rotate tool and tighten again. Fairly basic, no instructions but metal gears and when properly adjusted they don't seem to get hot in use. It's worth the money to me and if it weren't for the questionable quality control I'd give it to anyone I know who has a Dremel grinder. Since Revain is so good in terms of returns, I would recommend giving it a try.
