COBALT DRILL BIT 1/4" JOBBER LENGTH

Cobalt Drill Bit - 1/4" Jobber Length.  Also known as standard length drills, jobber drills are the most popular and widely used lengths that can be used in portable and machine drilling.  The 1/4" drill bit is 4" in length.

These cobalt drill bits have a 135° split point making them ideal for drilling through tough materials by hand. The 135° tip angle and the split point virtually eliminates drill “walking” when beginning a drilled hole.
