I recently purchased a router bit from Industrial and Scientific category and was extremely disappointed with the results. My analysis of this product showed that it was not only poor quality but also failed to meet industry standards. Although it had a relatively low price, it was not worth the investment as it broke after just one use. The only advantage is the thickness of the shank, but it is overshadowed by the poor quality of the tool. In conclusion, do not waste your money on thisβ¦
