Jobber Drill Metric

* Jobber-length drills are the most common type of drill * The length of the flutes is between nine and fourteen times the diameter of the drill, depending on the drill size * So a 1⁄2 in (12.7 mm) diameter drill will be able to drill a hole 4 1⁄2 in (114.3 mm) deep since it is nine times the diameter in length * A 1⁄8 in (3.2 mm) diameter drill can drill a hole 1 5⁄8 in (41.3 mm) deep since it is thirteen times the diameter in flute length * These jobber drill bits are manufactured from quality HSS-M2 for durability and long service life * Aircraft length drill *
