ALPEN 'Sprint' HSS Reduced Shank Jobber Drills
ALPEN reduced shank drill bits are necessary if you want to drill a hole larger than your chuck will allow.
As the drill bits are made of high speed steel they will cut faster than typical drill bits without losing their hardness or strength. 'Jobber' drill bits have a much longer length in comparison to their diameter which allows you to drill deeper than other drill bits.Â
