Review: Very good quality for price - High quality and consistent. First use was on an ancient Plymouth cast iron bellhousing- had to bore the registry to adapt an A833 OD bearing retainer apx .500 x/y and .070 z. That's a fair amount of material... the insert still looks very much as new after completion, so I'm pretty happy. Proper fit into the boring bar as well. Will buy more of this brand. Good mid/low price bargain for sure.
Review: Works great - Does what I bought it for
