Review on Yonico 14320 Carbide Spiral Finisher by Adam Johnson

I have not had the chance to use these bits but I can assure you they are very sharp and difficult to remove from the packaging they come in. I had to use pliers and wrap a rag around the shaft to get it out of the box. That was after I cut my finger trying. Losing a star was for that reason alone. I have purchased Yonico bits in the past and have always been pleased with their performance.
