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.
