Micro pilot drill geometries with 1-2xD flute length, large point angle, and positive diametrical tolerance allow them to optimize the guidance of a succeeding drill.
A pilot or spot drill, also known as a starter drill, is typically required when the succeeding drill is longer than 10xD or smaller than Ø 1.00 mm. Starter drills can also be used to improve hole location due to their short, rigid geometries.
The Sphinx Drinox Pilot Step Drill delivers up to three times longer tool life, three times higher coolant-through output and three times faster drilling.
The High-Performance Quadro Plus Drill Reamer geometry was developed to optimize performance and tool life in aluminum, cast iron, and plastic applications.
