When I first saw the price of these Yonico bits, I knew they MUST be very cheap, 'disposable', so I bought them with that mindset. I was very wrong! They resist anything I put in front of them. Even teak and Brazilian cherry are beautiful, smooth and even with no burn marks. I've recommended Yonico bits to all my friends, especially those who like to show off all the money they've invested in their expensive bit sets! They are LESS EXPENSIVE, NOT CHEAP, made by people who are tired of seeing…
