The Century Drill 5/64" left hand stub bit is built for backing out small broken screws, set screws, and snapped tap shanks. Reverse-rotation flutes grip and loosen the fastener as the bit cuts, so the work often comes free before you ever reach for an extractor. The shorter mechanic's length keeps the bit rigid and reduces wander in tight engine bays, panel boxes, and recessed assemblies.

• 5/64" 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 74104 (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 small screw extractor (No. 1 / EX-1 size class) for #6-#10 machine screws if the bit alone does not back the fastener out.
