• Taper Length HPC Cobalt High Performance Wide Land Parabolic Flute Drills• Wide Land Parabolic Flute Drills• The next generation in parabolic flute design, are effective in a wider range of materials and applications than standard parabolic flute drills• An Enhanced Flute Design with reinforced web provides increased drill strength and rigidity, straighter closer tolerance holes, improved chip formation and evacuation, improved coolant flow to the drill point and higher speeds and feeds for increased productivity• Titanium Aluminum Nitride Coating (TiALN)• Recommended for high thermal stress applications including dry machining, abrasive materials and hard-to-machine materials which generate higher cutting temperatures• TiALN actually forms a hard aluminum oxide layer in hot dry machining applications which reflects heat back into the chip and away from the tool while allowing higher speeds and feeds• High productivity with increased tool life• Longer flute length and longer overall length for increased reach and deeper hole drilling
