I needed a cutter but picked this set as I didn't have a decent sized cutter in my collection. The bevel turned out to be the most useful. Good quality bits in terms of value for money. I have other Yonico bits and I think they work well although not used very often so keep that in mind. I didn't have any rattling or burning with them and the cuts were smooth, but I mostly worked with pine. I would consider buying more Yonico bits in the future. Now if only I could find a 1r bit for less than 100.00.
