The Century Drill 5/32" left hand stub bit is built for extracting broken bolts, studs, and machine screws in the 1/4"-class fastener range. Reverse-rotation flutes loosen the fastener as the bit cuts, so the work often releases without a separate extractor. The mechanic's-length flute keeps the bit rigid for accurate starts in cramped quarters.

• 5/32" 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 74110 (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. 2-3 / EX-2-3 size class for 1/4"-5/16" bolts and broken tap shanks if the bit alone does not free the fastener.
