The Hertel Screw Machine Length Drill Bit delivers precision and durability for your metalworking projects. This 1/2" (0.5000) diameter bit features a 135-degree split point that reduces thrust and prevents walking when starting holes. Crafted from premium cobalt material with a straw finish, this bit offers superior heat resistance and extended tool life when working with harder materials. The 3-3/4" overall length with a 2-1/4" flute length makes it ideal for production drilling applications where shorter bits are preferred. Its regular spiral flute and right-hand cut design ensure efficient chip evacuation while maintaining hole accuracy. The straight shank provides secure mounting in your machine. Perfect for professional machinists and industrial applications requiring consistent, accurate holes in various metals.
