*Specal Hi-Molybdenum tool steel
*135 degree split point for fast penetration and accurate
starting without using a center punch
*Precision ground point, flutes, body, clearance and
drill diameter for the ultimate in accuracy and performance
*Body and clearance are gold treated for maximum lubricity
*Heat treated at 2185 degrees F and then nitro-carborized
finished at 950 degrees F to be measurable harder than
high speed steel
*Space age nitro-carrburized steel withstands
substantially higher drilling temperatures while
maintaining sharpness
*Recommended for use in work hardening grades of
stainless steel and other hard metal drilling applications |
