Century Drill Tool 73309 No. 9 Spiral Flute Screw Extractor

Product Description

The CENTURY DRILL TOOL CO INC 73309 is a No. 9 spiral flute screw extractor designed to remove broken bolts and screws that have snapped off inside a fastening hole. It handles bolt and screw sizes from 1-3/8 inches to 2 inches and removes broken pipe at 1 inch. Pairing this extractor with a 1-1/16 inch drill bit is required; left-hand cobalt drill bits are the recommended choice for best results. The spiral flute geometry bites aggressively into the broken fastener as the extractor is turned, gripping and backing out the damaged hardware cleanly. This extractor comes packaged as a set of 2.

Spiral flute screw extractors are a standard tool in the kit of any licensed plumber, pipefitter, HVAC technician, or general maintenance mechanic. This No. 9 extractor is suited for heavy-duty fastener removal tasks in both residential and light commercial settings. Typical applications include removing sheared bolts from flanges, pipe fittings, equipment housings, and structural connections. The extractor is especially useful when working on aging or corroded piping systems where fasteners are prone to breaking during disassembly.

Installation Notes

De-energize and lock out any equipment before beginning fastener removal work. Use the specified 1-1/16 inch drill bit to bore a pilot hole into the center of the broken fastener before inserting the extractor. Turn the extractor counterclockwise with a tap wrench or suitable driver to engage the flutes and back out the broken piece. Left-hand cobalt drill bits are strongly recommended because they resist the heat generated when drilling hardened or corroded fasteners.
