Value Collection C87760-6 Jobber Drill Bit 27/64 in

Product Description

The VALUE COLLECTION C87760-6 is a heavy-duty jobber-length drill bit designed for metal drilling in industrial and trade applications. It measures 27/64 inch (0.4200 inch decimal) in diameter with a 5-3/8 inch overall length and a 3-15/16 inch flute length. The bit is manufactured from M7 high-speed steel with a black and gold oxide coating that reduces friction and extends service life. A 135-degree split point starts drilling on contact without center-punching and reduces walking on hard materials. Right-hand cutting with a regular spiral flute, this bit is suited for machinists, maintenance technicians, and fabricators working in production or field environments.

This jobber drill bit is appropriate for general-purpose hole-making in steel, cast iron, aluminum, and similar metals. The straight cylindrical shank fits standard drill chucks on benchtop drill presses, magnetic drills, and hand-held power drills. The heavy-duty M7 grade and web-thinned tapered web construction make it well-suited for repetitive drilling cycles in shop or field maintenance work. This listing is for a package of 6 bits, making it practical for stocking a tool crib or equipping a crew.

Installation Notes

Drill bits in this size range are typically installed and operated by machinists, maintenance mechanics, or experienced tradespeople. Secure the shank fully in the chuck and verify the bit runs true before beginning a cut. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend bit life. Always wear eye protection and secure the workpiece before drilling.
