Worth its weight in gold if you ask me. I had a whole drawer full of old dull bits. I usually use the bench grinder to sharpen them, but I was sharpening them off center. I bought one of these sharpeners and I now have a entire drawer full of extremely sharp drill bits. I would thrown them away if it wasn't for this sharpener. I recommend one to everyone that complains about never having a sharp drill bit. I sharpened about 200+ drill bits in about an hour.
