R15B jobber drills are manufactured to NAS 907 Type B standards and available in letter sizes A to Z. They are suitable for both hand held and machine applications.

With a steam oxide finish which ensures clean, accurate holes by preventing workpiece material from sticking to the cutting surfaces of the drill, they are manufactured from premium High Speed steel for use in many materials including steel, aluminum and stainless steel.

R15B jobber drills have a split point to reduce the force needed to drill into the workpiece and as an aid to self-centering, producing more rounded holes.
