Review on 🔧 SPEED TIGER ISE Carbide Square End Mill - High-Quality Micro Grain End Mill for Alloy Steels/Hardened Steels - 2 Flute - ISE5/16"2T - Made in Taiwan (1 Piece, 5/16") by Charles Purnell

Bought on recommendation. Used for milling 404 stainless steel. Coiled with just one bit to mill 6 pieces and the bit was still in perfect shape. Destroyed 3 more windmills while trying to complete the job. I had to order new beats and buy them on the internet based on a recommendation. The company said it would use the speed and feed they proposed over traditional specs. Followed her instructions and used sewing machine oil as a lubricant. The result is excellent surface quality and phenomenal racquet durability. The Speed Tiger Carbide ISE cutters have exceeded all expectations and will be my go-to cutters for future needs.
