Century Drill 74108 Left Hand Drill Bit

Product Description

The CENTURY DRILL 74108 is a left hand drill bit designed for removing broken fasteners, stripped screws, and damaged bolts. It cuts in the counterclockwise direction, which often backs out a seized fastener during the drilling process before an extractor is even needed. This bit is a standard tool for mechanics, plumbers, electricians, and HVAC technicians who regularly deal with rusted or sheared hardware. At 0.014 pounds, it is a compact, lightweight precision bit suited for hand-drill or drill press use in both shop and field environments.

Left hand drill bits like the 74108 are used across residential and commercial service work wherever broken or stripped fasteners need to be removed without damaging the surrounding material. Typical applications include removing sheared bolts in flanges, extracting broken screws from housings, and clearing damaged hardware from equipment panels. This bit is a common addition to a service technician's fastener removal kit alongside screw extractors and easy-out sets.

Installation Notes

Left hand drill bits are installed by a technician into a standard reversible drill set to run in reverse. Before drilling, ensure the workpiece is secured and any adjacent systems are de-energized or shut off as required by the work area. Use appropriate cutting fluid when drilling into hardened steel to preserve bit life. Follow applicable safety codes and wear appropriate eye protection during fastener extraction operations.
