The further the tool does its work from the spindle, the more room for error. Deep pockets and cavities usually signify that a part is nearing completion, making the smallest of errors almost impossible to recover from and very costly.
The return on investment from digital boring comes from the time saved making adjustments on the spindle, as well as the increased adjustment accuracy.
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.
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.
