This 77mm Short Series Pilot Pin is a critical multi-function accessory engineered for industrial magnetic drilling applications. Designed to fit standard short-series annular cutters (30mm depth of cut), this hardened tool steel ejector pin ensures exact hole alignment. It automates internal coolant delivery and mechanically ejects the steel slug immediately upon hole completion.

• Precision Centring - Locates pre-drilled pilot holes or centre punches to ensure total positional accuracy before drilling begins.
• Automated Coolant Control - Retracts into the arbor as drilling starts, automatically opening the internal valve to allow coolant flow directly to the cutting edges.
• Automatic Slug Ejection - Utilises arbor spring tension to forcefully push out the solid metal core (slug) the instant the cutter breaks through.
• Heavy-Duty Construction - Forged from premium hardened steel to withstand extreme repetitive impacts and high-temperature environments.
• Universal Compatibility - Standard 6.35mm (1/4") shank diameter fits seamlessly across a wide variety of short-series mag drill cutters.
