The Century Drill 19/64" left hand stub bit is built for extracting larger broken bolts, studs, and structural fasteners. Reverse-rotation flutes loosen the fastener as the bit cuts, so the work often releases before an extractor is needed. The mechanic's-length flute provides the extra rigidity required when drilling into hardened bolt shanks.

• 19/64" 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 74119 (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. 4-5 / EX-4-5 size class for 3/8"-1/2" bolts, suspension/brake bolts, and engine mount fasteners if the bit alone does not free the fastener.
