Review on 🪚 SpeTool DownCut Carbide Cutter with Enhanced Cutting Diameter by Robert Yates

CNC insert. It's used on the CNC on Oak and runs slow at around 40 fpm at 0.05 depth. When the oak has knots, slow down to 30 fpm at 0.03 depth. If not a little, it will break very easily. On pine and other softwoods 60 fmp at 0.06, anything faster than that bit will break. I bought a pair from Amazon and used them for about 8 hours. Lowe's 1/8 bits last 20 times longer than the $3 more expensive bits.
