Shop Industrial Drill Bits & Drill Bit Sets on Amazon.com
Industrial drill bits cover a range styles for drilling applications, including jobber, mechanical, and aircraft extension bits. Typically made from carbide or high-speed steel, they require consistent cutting edge maintenance with an industrial drill bit sharpener. Most professional drill bits require a pilot, or starter hole, before drilling. Some, however, include a special point that allows the industrial bit to penetrate the material without a predrilled hole. A tool's cutting angle and helix angle determine how fast it can cut and what types of materials it is suitable for. Some are specifically designed for softer, gummier materials such as aluminum, where efficient chip evacuation is required, while others are manufactured to cut hard materials such as carbon steel. Industrial drill bit sets may include a combination of bit types or the same style in a range of sizes that vary by cutting diameter, shank diameter, flute length, and overall length.
