Jobber Length Drills

Jobber Length Drills

Jobber drill bits are straight shank drills suitable for general purpose applications. This category  includes  bright, treated, TiN coated drills to machine a variety of materials. Heavy duty-split point drills, high helix and para-flute jobber drills along with cobalt bits meet the needs of most machinists. Treatments and coatings add to the life of these jobber drills.  Split points make it easier to start drilling due to the design eliminating the need for a pilot hole.

Regal’s “NATIONAL” brand of jobber drill bits include 117 sizes of fractional, number and letter sizes and are also available from 1 to 14 millimeters.

Aircraft style jobber drills are an important part of our offering and comply with AIA specifications. We also manufacture a wide variety of special jobber drills to meet our customers needs.
