This router bit did not meet my expectations... The quality is subpar and caused the bit to dull quickly. It was not able to handle tougher materials causing it to break after minimal use. However it did have a decent initial sharpness. Overall, I do not recommend this product to those IN need of a durable and long-lasting router bit for their Industrial and Scientific needs..
Pros
High-quality cutting tool that is durable and long-lasting
Cons
Requires careful handling due to its sharpness and should be kept out of reach of children or inexperienced users
will not work with HPU foam. 1/32" deep cutout in 15# HDU foam cannot be removed. The chisel deflects and creates partial gouges, and it's scary to watch. Don't you dare run that thing over 12,000 RPM. If you Don't cut styrofoam, don't do it!
