Century Drill Tool 74119 Lh Cobalt Stub Drill Bit 19/64 in

Product Description

The CENTURY DRILL TOOL CO INC 74119 is a 19/64-inch left-hand cobalt stub drill bit built for professional mechanics and trade technicians who need reliable reverse-rotation drilling for broken fastener extraction. The bit is manufactured from cobalt steel and features an industrial polished finish with a 135-degree split point for fast, accurate starts without center punching. Its stubby mechanics length design keeps the bit rigid under load, reducing flex and improving control in tight or confined work areas where standard-length bits are impractical.

This bit is suited for industrial and commercial maintenance work, automotive service, and mechanical repair applications where left-hand rotation is required to back out stripped, snapped, or seized fasteners. The 135-degree split point performs well in harder metals and alloys commonly encountered in mechanical and structural fastener removal. It ships in a package of 3 units, making it practical for shop stocking or field kit replenishment.

Key Features

• Left-hand rotation for broken fastener extraction without a separate extractor in many cases
• Cobalt steel construction for heat resistance and extended tool life in hard materials
• 135-degree split point for self-centering starts and reduced walking
• Stubby mechanics length increases rigidity and strength compared to jobber-length bits
• Industrial polished finish reduces friction and aids chip clearance
• Sold in a package of 3 for shop or field use

Compatibility

Designed for use in any standard 3/8-inch or larger left-hand-capable drill chuck or reversible drill press accepting round-shank bits of 19/64-inch diameter.

Installation Notes

Left-hand drill bits are installed and used with the drill set to reverse rotation. Secure the workpiece firmly before drilling to prevent movement during bit contact. Wear appropriate eye protection and follow shop safety protocols when drilling into metal fasteners. Use cutting fluid on harder alloys to reduce heat buildup and extend bit life.
