1/4" Compression Bit
I don't have anything to compare to, but it seemed to do the job well. I feel like it was money well spent. I trust the quality.

1/4" Compression Bit For CNC Routers, 1/4" Shank - feedback
Overall, I love these bits. My favorite is still the 3/16" version but in the interest of saving some run time, I converted my program to the 1/4" instead. I am cutting 3/4" thick HDPE and I do have to occasionally clean out the chips during the cut, otherwise they tend to fuse back together. The 3/16" version does not do that. I am running it at 17,000 rpm and 95fpm feed.
