Review on SPEED TIGER Carbide Stainless Square by Joseph Hall

I have tried many end mills and they have always burned out, like the 24k spindle. I bought one of these for hardened steel and stainless steel that I needed to route and this one end mill I have an actual cutting time of: 6 hours contact in hardened steel and 11 hours total in stainless steel and it still cuts through space like a hot knife . temperature oil. 3137 rpm at a speed of approx. 650 mm/min works perfectly with any metal. First order from this company and not the last as all my purchases are made from this company.
