Review on 🔧 Polished MMO5 32 4FSE Drill America by Michael Glassburn

It's hard to find a 3/16" end mill with a long cut or a shank the same diameter as the cutting face. That fits the bill. We have a selection of these for cutting round holes through rubber stoppers about 1 inch thick. Regular drill bits aren't designed to cut through the sidewalls of the rubber, so they just push it aside leaving a very rough cut. End mills work much better and this one is perfect for small 3/16" holes.
