Cleveland C71112 Jobber Drill Bit Wire Size 12 Hss

Product Description

The CLEVELAND C71112 is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastics. Built from high speed steel with an oxide coating, it resists heat and wear under typical shop conditions. The bit is sized to wire gauge number 12, which corresponds to a decimal diameter of 0.1890 inches, and features a standard 118-degree split point for accurate starting without a center punch. Overall length is 3.5 inches with a 2.3125-inch flute length, making it well-suited for through-hole and blind-hole work in a wide range of materials. A licensed mechanic, machinist, or maintenance technician handles this type of tooling in production and repair settings.

This bit fits standard drilling applications where a wire-gauge size 12 hole is required. The straight-cylindrical shank seats securely in 3-jaw drill chucks on hand drills, drill presses, and CNC machines equipped for straight-shank tooling. The 2-flute spiral design promotes chip evacuation during drilling, reducing heat buildup at the cutting edge. It is cataloged under Cleveland Series 2001G and carries a regular spiral with a tapered, web-thinned construction for reduced thrust force.

Compatibility

Designed as a general-purpose jobber-length drill bit suitable for use in any drill press, hand drill, or machine tool equipped with a standard 3-jaw chuck accepting a 0.1890-inch straight-cylindrical shank.

Installation Notes

Machinists and maintenance technicians should secure the shank fully in the chuck and verify runout before drilling. Disengage and lock out power to the machine before changing bits. Use appropriate cutting fluid for ferrous metals to extend tool life and maintain hole tolerance. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is observed.
