The Micro 100 Drill Mill Carbide is a high-performance drill bit for milling and drilling. It has a 135-degree split point tip for fast, accurate starts and reduced thrust. With 16% cobalt, it offers increased wear and heat resistance. The bit has a 0.039" diameter and 1" length, made of solid carbide for durability. Its 1/8" reduced shank fits standard chucks. Ideal for milling small slots, holes, contours, and profiles in steels, cast iron, non-ferrous metals, fiberglass, and some plastics, it achieves precise, clean results in tight spaces.
