Reamers are certainly not the be all and end all of hole boring, but if you’ve never used one, give it a try. Here’s what G-Wizard would suggest for reamer speeds and feeds with a 3/16″ HSS Reamer in 300 series stainless, which was the question in the post: A 3/16″ reamer going 1″ deep in 304 stainless should run 458 rpm and 2.75 ipm feed.
