Cobalt Taper Length Drill Bits Cobalt HSS Drill Bits, Heavy Duty Fractional Sizes QC91CO - Cobalt HSS, Wide Land Parabolic Flute Design, Bronze Color Oxide, 135° Split Point Especially effective in deep hole drilling; unique flute form produces closer tolerances due to improved chip and coolant flow and higher torsional rigidity. 135° self centering split point reduces thrust. Taper length (longer flute and overall length) improves reach and deep hole drilling capability. Used for drilling high alloy steels, titanium, Inconel, PH stainless and other difficult to machine materials.   Diameter, Inch Flute Length, Inch Overall Length, Inch Pkg Qty Price Pkg.
