  • Five extractor sizes cover common screw diameters
  • Ten-piece set includes matched drills and extractors

10-Piece Extractor Set

This Neiko set combines five machined alloy screw extractors with five left-hand cobalt drill bits in a single 10-piece kit. The extractors range from No.1 to No.5 while the drill bits cover 5/64, 7/64, 5/32, 1/4, and 19/64-inch sizes. Multi-fluted extractor design grips broken fasteners securely for reliable removal. Left-hand drill rotation helps loosen seized screws during the drilling process.

Mechanics and DIY users

Suits technicians and DIYers who regularly encounter broken, stripped or seized fasteners in automotive and maintenance work. The cobalt bits handle hardened steel while the extractor range covers common small to medium bolt sizes. Buyers needing larger extractor sizes or a wider range of drill diameters should look at something else. Sets without left-hand drill bits will not offer the same loosening action while drilling.

Highlights

  • Removes broken screws easily with multi-fluted extractors
  • Left-hand cobalt bits drill into damaged fasteners
  • Five extractor sizes cover common screw diameters
  • Ten-piece set includes matched drills and extractors

Questions about this item

How deep can the 5/64-inch cobalt drill bit go before it overheats during continuous extraction?

The cobalt construction resists heat buildup better than standard steel, letting the 5/64-inch bit maintain cutting speed through multiple broken screws without cooling pauses.

Does the multi-fluted No.3 extractor vibrate enough to loosen adjacent bolts when run all day?

Multi-fluted geometry distributes cutting force evenly, so the No.3 extractor runs smoothly at drill speed and adds negligible vibration to surrounding fasteners.
