Product Description
The Century Drill Tool Co Inc 73406 is a No. 6 spiral flute screw extractor designed to remove broken bolts, screws, and pipe fittings that have snapped off flush or below the surface of a workpiece. This 3-pack handles bolt and screw diameters from 5/8 inches to 7/8 inches and removes 3/8-inch pipe. The spiral flute design bites aggressively into damaged fasteners as reverse torque is applied, giving technicians and tradespeople a reliable grip even on corroded or seized hardware. A 13/32-inch pilot hole is required before use, and left-hand cobalt drill bits are strongly recommended for this operation.
This extractor is a standard tool for plumbers, HVAC technicians, electricians, and general maintenance professionals working on pipe fittings, equipment panels, and structural fasteners. It is well-suited for residential and light commercial applications where broken fasteners are a routine service obstacle. The 3-pack format provides backup extractors for repetitive jobs or situations where a first extraction attempt results in extractor wear.
Key Features
- Removes broken bolts and screws from 5/8 inches to 7/8 inches in diameter
- Removes broken 3/8-inch pipe fittings
- Spiral flute geometry bites aggressively under reverse torque
- Requires 13/32-inch pilot hole; compatible with left-hand cobalt drill bits
- Sold as a 3-pack (3 extractors per package)
Compatibility
Designed for use on broken bolts and screws ranging from 5/8 inches to 7/8 inches and broken 3/8-inch pipe. Use with a 13/32-inch drill bit; left-hand cobalt drill bits are recommended to maximize extraction success.
Installation Notes
Extraction work should be performed by a qualified tradesperson familiar with reverse-drilling technique. Before attempting removal, secure the workpiece and ensure all energy sources to the associated equipment are locked out and tagged out per applicable safety procedures. Drill the pilot hole to the correct depth using a 13/32-inch left-hand cobalt bit before inserting the extractor. Apply steady, controlled reverse torque with a tap wrench or drill set to reverse; excessive force can break the extractor in the hole.
