Hey guys, I'm having a little trouble getting more life out my 3/4 inch carbide endmills. I only get to use them about twice before they need to be resharpened. Granted each time is on a 6 to 8 foot brake that I mill. I only have it running at .1 Z depth and it only fully engaged on each part for 200 to 300 inches at about .050 depth. The rest of it is side milling maybe .05. I'm cutting 1145 steel and my endmills are solid carbide. I'm using flood coolant, spinning the endmills at 1790 RPM, and feeding at 30 IPM. This next time I'll try it at 20 IPM. What am I doing wrong? Thanks!
