The bit has a body having at least one leg depending therefrom, a bearing pin secured to each leg, and a rotary cutting cone mounted to the bearing pin. The cone has a conical gage surface. The gage scraper mounts on the inside of each leg and protrudes from the leg toward the cone into close proximity with the gage surface.
