this was a great purchase, my employer provides a greenlee set on all our trucks and this tko really seems to be just as good. i have owned a few other brands which all look very similar but this one seems to stay sharp and keep its teeth longer. as with all metal cutting bits keep it slow, the slower the better if you want it to last a while
