snippet: Features: <ul><li>High Speed Tool Steel; 62/65 Rc </li> <li>Jobber lengths </li> <li>10 microinch finish or better </li> <li>Marked with size </li> </ul> Wire-size high-speed steel drill bit blanks come in standard sizes that correspond to American Wire Gauge (AWG) sizes. This ensure compatibility when inserting a wire of the same wire size into the hole created by the tool. The larger the wire size, the smaller the blank. High-speed steel drill bit blanks are the most common choice for creating custom drill bits with precise dimensions to suit a certain application. They are less brittle than cobalt and carbide drill bit blanks.
