As an industrial and scientific user of cutting tools I was excited to test out this Router Bit. However, as my tests showed, it fell short of my expectations .While it did provide clean cuts, the bit wore down quickly and required frequent replacements. The quality of this product was lacking compared to others in the market..
Router bearings have come loose and fallen off on two different bits. Make sure the 2nd was tight and still loose. This has never happened with Home Depot or Lowe's cutters.
