THE APPLICATION OF AVYAC HIGH-PERFORMANCE DRILLING TECHNOLOGY NOT ONLY DOUBLES DRILLING PRODUCTIVITY (HALVING DRILLING COSTS) BUT HOLDS 6 SIGMA SPC HOLE SIZE- GEOMETRY-LOCATION TOLERANCES. IT APPLIES TO PRESENT HSS/COBALT AND CARBIDE TWO/THREE FLUTE DRILLS DRILLING WORKPIECES ON MACHINES. IT APPLIES TO ALL METALS FROM SOFT CAST ALUMINUMS TO RC 55 TOOL STEELS AS WELL AS CARBON/GRAPHITE AND KEVLAR FILAMENT COMPOSITES. THE KEY IS A TRULY SELF-CENTERING UNIVERSAL SIX-FACET POINT THAT DRILLS AT 200% CONVENTIONAL/HANDBOOK FEED RATES PLUS WEB THINNING/SPLIT POINTING FOR CORRECTION/COMPENSATION OF DRILL TOOL ALLOWED ERRORS. THE DRILL POINT AXIS OF THIS SELF- CENTERING GEOMETRY ACTS AS A PIVOT BEARING, MAKING IT POSSIBLE TO PREDETERMINE ALL HOLE TOLERANCES.
