Review on Ultimate Guide to KOWOOD Router Pieces for Woodwork Beginners by Aaron Johnson

I am basically satisfied with the set. Since I only used 3 bits I will say that the even 1/8 and 1/4 bits worked as I intended. I can't confirm durability. 1/2" router bit, I was disappointed. The material was 200 year old black walnut. My cutting speed was 18000+-. The depth of the router bit was 1/4". I beveled about 10 feet and the pilot bearing seized and the Cutting edge has started to break Note: After sending an email and a picture to customer service, they made it clear that the bitrate was too high in their reply I will buy something about one high price, I know it will put an end to my vanity. My father told me over 50 years ago to buy the best you can afford. I will heed that advice next time.
