Type 671 Fractional - 140º Point With Negative Edge
Carbide Tipped
  • 140º point designed for drilling tough abrasive or high tensile materials
  • Die drill - negative angle cutting edge
  • 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
  • Modified metric tool diameter
  • Modified point and / or angle
  • Shortened shank or reduced shank diameter
  • Reduced shank diameter
  • Flat(s) on shank
  • Coatings available:
  •  TITANIUM NITRIDE - TiN 
     TITANIUM CARBONITRIDE - TiCN 
     ZIRCONIUM NITRIDE - ZrN 
     AL TITANIUM NITRIDE - AITiN 
Use:
  • For drilling hardened steel in the range of 35 to 65 Rockwell C
  • Will cut without annealing the workpiece
  • Light feed with steady pressure - clear chips frequently
  • Flood the cutting point with coolant
