Review on Amana 51520 ALUMINUM FLUSH TRIM: The Perfect Precision Tool for Flawless Trimming by Joel Young

We have had problems with Amana bit bearings in the past but decided to try again. The two new bits fired up the bearings almost immediately. This happened with both wood cutters and metal cutters. We are a manufacturing facility with experienced operators, so we believe we have eliminated operator or application error. In the future we will look for other bit manufacturers.
