Cleveland C71101 Jobber Length Drill Bit Wire Size 1

Product Description

The CLEVELAND C71101 is a jobber length drill bit designed for general-purpose drilling in metal, wood, and plastic. Ground from high speed steel and finished with an oxide coating for improved lubricity and corrosion resistance, this bit is built for consistent performance in production and maintenance environments. It carries a wire gauge size of 1, equal to 0.2280 inches in decimal, and features a standard 118-degree split point for accurate starting without a center punch. Overall length is 3.875 inches, with a 2.625-inch spiral flute section. Licensed machinists, tool-room techs, and maintenance tradespeople are the typical users.

The C71101 is suited for light to medium drilling in ferrous and non-ferrous materials. Its regular spiral, two-flute configuration handles chip evacuation efficiently in through-hole and blind-hole applications. The straight cylindrical shank fits standard drill chucks without adapters. This bit is appropriate for bench drill presses, hand drills, and CNC drilling fixtures where a 0.2280-inch bore is required. It meets ASME B94.11M and DIN 338 standards, making it a recognized fit for shops that maintain tooling specifications.

Compatibility

Designed as a general-purpose jobber length drill bit for use in standard three-jaw drill chucks across bench drill presses, hand drills, and CNC drilling fixtures accepting a straight cylindrical shank at 0.2280 inches diameter.

Installation Notes

Install in a properly sized three-jaw chuck and tighten with a chuck key before starting the spindle. Disconnect power to the machine before changing tooling. Apply cutting fluid when drilling ferrous materials to extend tool life and maintain tolerance. Do not exceed the drill press or hand tool rated speed for the material being drilled.
