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.
