CENTURY LEFT HAND STUB DRILL BIT 7/64"The Century Drill 7/64" left hand stub bit is built for extracting small broken bolts, studs, and machine screws. Reverse-rotation flutes loosen the fastener as the bit cuts, often backing the work out before an extractor is needed. The mechanic's-length flute keeps the bit short and rigid for precise work in tight spaces.
- 7/64" 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 74107 (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 and small set screws if the bit alone does not free the fastener.
