🔪 MIBRO Adjustable Circle Cutter: Simplifying Precision Cutting Effortlessly Review

This is a handy little tool! I have to admit I didn't use it the way it was supposed to be used (in a drill press) but I used it in a hand drill and it did the job every time.

This hole was a bit more labor intensive than the reservoir as the cutter was able to grab the material and stop hard because I tilted the bit a bit. . I've never seen wear on an HSS cutter, but if it starts to
