S&D Reduced Shank Drill Bit

High Speed Steel S&D drill bits offer superior performance over conventional HSS drills. Their Nitride treated, heavy-duty construction increases tool life and performance. 118 degree Split Point reduces walking at the drill point and makes these drills ideal for both hand held and CNC Operations. Black & Gold surface treatment for maximum lubricity. Usable in a wide range of materials including difficult to machine materials such as stainless steel. S&D drills expand the size range capacity of a 1/2" portable drill chuck.

  1. Feeds – Feed rates for drilling are governed by the drill diameter, machinability of materials and depth of hole.
  2. Speeds – The speed of a drill is determined by the rate which the outer periphery of the tool rotates in relation to material being cut. In general, the SFM at which a drill will operate is within a range based upon the workpiece material, its condition, hardness and depth of hole. It is usually advisable to start the drilling process at a slower SFM and then increase to the maximum.
  3. RPM = (SFM x 3.82) divided by TD = Revolutions Per Minute
  4. SFM = RPM x TD x .262 = Surface Feet Per Minute
  5. TD – Tool diameter in inches
