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.
Boring inserts including pressed and ground-geometry inserts are available through BIG DAISHOWA to help optimize performance and tool life in boring applications.
Chamfering the entry and exit of 0.80mm to 6.00mm holes can be a tedious, time-consuming process. The Noventa from SPHINX can transform this process using an innovative geometry that improves cycle time, tool life and surface quality.
Dialing in a finishing job can be meticulous, with several measurements, adjustments and discussions taking place. That not only costs time, but those tool touches and interactions introduce some risk inside a shop. Our next boring innovation will help eliminate many of those repeated interactions and extra adjustments.
