12" Hex 8 & 10 Dual Locking Hole Saw Pilot Bit Extension Rapid Core Eject®

Spyder® Hex 8 and Hex 10 Dual Locking Hole Saw Pilot Bit Extensions are engineered to deliver secure, extended reach for demanding hole cutting applications. Featuring Spyder AUTO LOCK Technology, this auto-locking extension allows for fast, tool-free installation while a secondary twist lock helps retain the hole saw for reliable performance. Designed for compatibility with both Hex8 (3/8-in hex, 1/2-20 thread) and Hex10 (1/2-in hex, 5/8-18 thread) arbors, it provides versatile jobsite functionality. Integrated hex arbor adapter torque pins help prevent the saw from becoming wedged onto the arbor, making saw changes quick and efficient. For safe operation, always use a drill motor equipped with a support handle and operate in standard rotary drilling mode only — not for use in hammer or impacting drill modes.
