I think same way Robert says. I purchased two different reducers, one from amazon ;
Other one is from Amana Tools;
First one failed in maybe two weeks, started to drop the bit.
Other Amana tool one never failed, but Looks like I lost my trust after first experience.
I decided to buy 1/8" collet. It was great. I made a mistake once, while I’m tiding the collet, bit was drop too much I didn’t realized and I gave damage to Collet. It was one time mistake deal. Now when I need to change bit, I need extra-extra force to release it.
Nothing like original. I have already return back to Amana Tool reducer. Means you have two alternatives, both have problems. Like, both ends shitty stick, you have to make a decision which end you want to hold.
