The Century Drill 13/32" left hand stub bit is built for extracting heavy-duty broken bolts, studs, and structural fasteners. Reverse-rotation flutes loosen the fastener as the bit cuts, so the work often releases without a separate extractor. The mechanic's-length flute provides the rigidity required when drilling into large hardened bolt shanks.

• 13/32" cutting diameter, left hand (reverse) spiral
• Mechanic's-length flute for added rigidity in tight clearances
• 135 deg split point starts on contact without a center punch
• Cobalt-steel construction for heat resistance on hardened fasteners
• Industrial polished finish
• MPN 74126 (Century 7411X/7412X left-hand cobalt stub series, numbered by 64ths)

Tip: Run the drill in reverse at low RPM with steady pressure. Pair with a screw extractor in the No. 5-6 / EX-5-6 size class for 1/2"-3/4" bolts, manifold studs, and cylinder-head bolts if the bit alone does not free the fastener.
