My analysis of this product showed that it was lacking in quality compared to other router bits I've used in the past... Despite its low price point, the Yakamoz bit proved to be ineffective and struggled to cut through the wood. i had to apply excessive pressure for it to even make a dent, which is unacceptable for an industrial and scientific cutting tool. The only pro I can list is its affordability, but in this case, you truly get what you pay for. Overall, I would not recommend this product to any serious woodworker..
