Cleveland C71156 Jobber Length Drill Bit Wire Size 56

Product Description

The CLEVELAND C71156 is a wire gauge size 56 jobber length drill bit designed for general-purpose drilling in metal, plastic, and similar materials. It is manufactured from high speed steel with an oxide coating that reduces friction and extends service life under moderate heat. The bit measures 1.75 inches overall length with a 0.75 inch flute length and a decimal diameter of 0.0465 inches. The 118-degree standard point angle suits a wide range of common shop and field drilling tasks. The straight-cylindrical shank seats cleanly in standard drill chucks, and the 2-flute right-hand spiral flute design clears chips efficiently during through-hole operations. Licensed machinists, millwrights, HVAC techs, and electricians drilling small-diameter pilot or clearance holes will find this bit a reliable everyday tool.

The C71156 is suited for light-duty precision drilling where small wire gauge sizes are required. Typical applications include pilot holes for self-tapping fasteners, clearance holes in sheet metal and thin-gauge panel work, and detail drilling on HVAC cabinets, electrical enclosures, and mechanical assemblies. The regular spiral type and tapered web with web-thinning reduce feed force and improve point stability on entry, which is particularly useful when working with thin-wall material or in confined spaces on equipment. This bit is sold individually per package.

Key Features

• Wire gauge size 56, 0.0465 inch decimal diameter for fine-tolerance drilling
• High speed steel construction with oxide coating for reduced friction and extended tool life
• 118-degree standard point angle with web-thinned tapered web for easy penetration
• 2-flute right-hand spiral for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks without adapters
• Meets ASME B94.11M and DIN 338 standards for dimensional accuracy and performance

Compatibility

Designed as a general-purpose jobber length drill bit compatible with any standard drill chuck accepting a 0.0465 inch straight-cylindrical shank, including benchtop drill presses, hand drills, and CNC drill units configured for wire gauge tooling.

Installation Notes

Installation of this bit should be performed by a qualified technician familiar with small-diameter tooling. Secure the shank fully in the chuck and verify concentricity before drilling to prevent bit deflection or breakage at this diameter. Use appropriate cutting fluid when drilling ferrous materials to preserve edge life. Always wear eye protection and ensure the workpiece is firmly clamped before operation.
