Irwin 53704 Spiral Flute Screw Extractor Drill Set 2 Pc

Product Description

The IRWIN 53704 is a 2-piece spiral flute screw extractor and drill set designed to remove broken, damaged, or seized fasteners from metal and other materials. The set includes one 1/4-inch drill bit and six spiral screw extractors sized 1 through 6, covering a screw size range of 9/32 to 3/8 inches and M8 to M10 metric fasteners. The spiral flute design bites into the damaged fastener as the extractor turns counterclockwise, increasing grip the harder it is turned. This set is used by HVAC technicians, plumbers, electricians, and general tradespeople who regularly encounter stripped or broken hardware in the field.

This extractor set is suited for residential and light commercial service work where fasteners become rounded, snapped, or otherwise unremovable by conventional means. It handles 1/8 BSP and 1/8 NPT fittings along with standard inch and metric fasteners in the covered size range. The compact 2-piece package makes it practical for a service van or tool bag. Trades that work with pipe fittings, electrical enclosures, mechanical equipment mounts, and similar hardware will find the covered size range directly applicable to common field fastener diameters.

Installation Notes

Screw extractors are typically used by licensed tradespeople working on mechanical, plumbing, and electrical equipment. Before attempting extraction, ensure the equipment is de-energized, depressurized, and safe to work on per applicable codes. Drill the pilot hole with the included 1/4-inch bit before inserting the extractor. Apply steady counterclockwise torque with a tap wrench or similar holding tool — do not use impact drivers, as excessive force can snap the extractor in the bore.
