Jobber Length Drill Bit: #48, 118° 4-Facet Point, Solid Carbide

These general purpose solid carbide jobber-length drill bits for metal and plastic have regular spiral flutes that are best suited for nonchipping hard materials such as nonferrous metals, cast iron, and structural steel. Carbide drill bits provide excellent hardness, wear resistance, and heat resistance when drilling hard material. They are more durable than carbide-tipped bits when creating precision holes in hard materials, and are harder than high-speed steel and cobalt drill bits. Bright (Uncoated) drill bits can be resharpened and are a good choice when drilling soft materials such as aluminum and low-carbon steel. Jobber-Length drill bits are the most commonly used and provide a good balance of strength and accuracy when drilling into a variety of materials.
