1/4" Reduced Shank HSS Twist Drills
* Made from High speed steel, Standard right hand spiral.
* General purpose lengths are proportional to be drill diameter.
* 135 degree split point for quick start and no walk application.
118 degree point angle design for general purpose are available on request.
* HSS cobalt high speed steel are available on request.
* 1/4" Reduced Shank Jobber Length Drills are used for drilling holes larger than the capacity
of a 1/4" drill chuck. Reduced shank drills should only be used for light to medium duty drilling
applications as they do not have the torque strength of a straight shank drill. Reduced shank
is not as hard as the body of drill to allow more flex and less breakage.
* For drilling applications in a wide range of normal ferrous and non-ferrous metals as well as
non-metallic materials.
* Black oxide finish or Bright finish or Titanium Coated are available on request.
* Round Shank or 3 Flat Shank are available on request.
* Drill Bits Set are available on request.
