Comparing these to expensive bits of the same type, these do 80% of the work at about 5% of the price. If this is good enough for you, great. I use these and occasionally find them indispensable, but every time I use them I am irked by their imprecision and the destruction they wreak if I'm in a stupid hurry and don't step up one by one to the size I ultimately need. They are big bruisers and need a drill press with very low runout, or they'll tear up your workpiece and likely rip up your hand, too. They will rapidly make square holes if you let them. When feasible, I opt for other types of drill bits -- forstner or hole saws, for instance -- to avoid using these. Be sure to clamp your workpiece very well.
