That sounds like something a parent would say to their child when purchasing their first car. I'm pretty sure we are not all naive teenagers and know that Onsrud are listing them due to various reasons like odd sizing (which they clearly state in the description). If it was an unknown business listing them cheaply I would be more cautious but because it is Onsrud I feel more than confident the product I'm getting is up to quality standards.
Due to how many 7/32 bits I've bought (all on a 1/4 shank), I now cut the majority of my wood based on those specs. I know at the end of the day that purchasing them saved me thousands of dollars and that I got a 'Bargain' from my smart move. Why pay full price when some of these Onsrud bits will perform just as good if not better at a much cheaper price?
