Knife broke before I could use it. The 1/4" ejector pin could not be passed through the center hole because it tapers near the cutting edge. I tried to force it and the tip broke. This pin fits all my other front teeth. I don't know if it's defective or if this cutter uses a custom-sized pin. I haven't found a PIN specification or a way to contact the seller to discuss the issue. Cutter has never been in a magnetic drill.
