Type 673 Fractional - 140º Point With Positive Edge
Carbide Tipped
  • 140º point designed for drilling tough abrasive or high tensile materials
  • Thinned web which permits higher feed rates with less spindle power
  • Drill body diameter smaller than tool diameter to prevent gauling
  • Carbide tip high temperature brazed to hardened tool steel body
  • Smooth flutes for effective chip flow
  • Precision ground to insure concentricity of tip & body
  • All dimensional & element tolerances conform to one of:
    ASME/ANSI B94.11M
    ISO - International Organization for Standardization
    NAS 907 - National Aerospace Standards
    USCTI - United States Cutting Tool Institute (formerly MCTI)
 		  Modifications: (Prompt delivery)
  • Modified tool diameter
