Cleveland C72127 Jobber Drill Bit Wire 27 Hss 3 in

Product Description

The CLEVELAND C72127 is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastics. Manufactured from high speed steel with a bright uncoated finish, this bit runs in right-hand rotation with a standard 118-degree split-point angle and a regular spiral flute geometry. The overall length measures 3 inches with a 1-7/8-inch flute length, giving it the reach needed for common through-hole and blind-hole applications. The straight-cylindrical shank diameter is 0.1440 inches, matching the wire size 27 designation with a decimal equivalent of 0.1440 inches. Two flutes and a web-thinned, tapered web configuration reduce thrust and improve chip evacuation on standard drill presses and hand drills.

This bit is suited for light-duty to medium-duty drilling tasks in maintenance, fabrication, and field service environments. The Series 2002G construction meets ASME B94.11M and DIN 338 standards, making it appropriate for shops and trades that work to recognized dimensional and tolerance specifications. The 4xD flute-to-diameter ratio supports adequate chip clearance in shallow-to-moderate depth holes. Typical users include machinists, pipefitters, electricians, and general maintenance technicians who need a reliable, standard-geometry jobber bit for everyday drilling.

Key Features

• Wire size 27 with 0.1440-inch decimal diameter and diameter tolerance of -0.0007 to 0.0000 inches for consistent hole sizing
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High speed steel construction suitable for steel, aluminum, wood, and plastic
• Bright uncoated finish — no coating buildup to affect hole diameter in tight-tolerance applications
• Regular spiral, right-hand cut with 2 flutes and 4xD flute-by-diameter ratio for efficient chip removal
• Meets ASME B94.11M and DIN 338 dimensional standards

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard 3-jaw drill chucks accepting a 0.1440-inch straight-cylindrical shank. Fits conventional drill presses, hand drills, and right-angle drills configured for wire-gauge or fractional-size tooling in the 0.1000-to-0.1500-inch diameter range.

Installation Notes

Install this bit in a clean, properly sized chuck and tighten securely before operation to prevent shank slippage and runout. Always power down and de-energize the drill or press before changing bits. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and maintain dimensional accuracy. Wear eye protection in accordance with applicable shop safety requirements.
