As a result of my tests, I determined that this straight router bit is top-notch. It made quick and accurate cuts in a variety of materials without any chipping or tear-out. The carbide-tipped blade maintained its sharpness even after prolonged use. However, the price is on the higher end for a single router bit.
Excellent plunge drill! Cuts a very clean hole. I will buy others like it. I've only used it a couple of times so I don't know how long it will keep its sharp edge.
