The PTI Long Pilot Drill is specifically designed for use with 50mm annular cutters. It plays a crucial role in broaching operations by ejecting the slug from the centre of the cutter upon completion of the hole, and it provides a central focal point for accurate positioning on pre-marked steel. The pilot pin also retracts into the arbor, allowing coolant to flow inside the cutting teeth, which helps to extend tool life. Material : Hardened steel. Dimensions : 6.34 x 103mm. Function : Ejects the slug and provides central positioning for accurate drilling. Coolant Flow : Retracts into the arbor to facilitate coolant flow, enhancing tool longevity. Brand : PTI
