Don't take a deep cut slowly, take a light cut and keep the feed rate up. This prevents localized heating of the workpiece material. Also, I don't use any plain HSS tools, I use M42 or higher Cobalt HSS, which keeps a sharp edge MUCH longer. For the small stuff, I use 1/8" solid carbide end mills, these work really great.
