This Greenlee replacement pilot drill is made from cobalt-steel with a split-point tip that resists walking and starts fast — keeping hole cutter arbor setups accurate and productive when punching through metal enclosures and panels on the job site. Designed as a direct replacement for Greenlee carbide hole cutter arbors, it delivers pro-grade performance and maintains cutting precision through demanding applications. The 1/4" diameter and 4-1/8" overall length make it a straightforward drop-in fit for compatible Greenlee arbor assemblies.
