13 Piece Jobber Drill Replacement Set
13 Piece pack of Premium Black & Gold Jobber Drills.
Made of special Hi-Molybdenum tool steel. 135°split point provides fast penetration and accurate starting without a center punch. Precision ground point, flutes, body, clearance and drill diameter results in ultimate accuracy and performance. Body and clearance are gold surface treated therefore providing maximum lubricity. Drills are heat treated at 2185°F and then nitro-carburize finished at 950°F resulting in measurably harder than high speed steel. Because space age steel can withstand substantially higher drill temperatures, bits maintain sharpness. Use in work hardening grades of stainless steel and other hard metal drilling applications. All Drill Bits come individually packaged and labeled for easy identification. Replace the first row of a Standard Index Kit!
