Cleveland C72154 Jobber Length Drill Bit Wire 54 Hss

Product Description

The CLEVELAND C72154 is a wire gauge size 54 jobber length drill bit designed for general-purpose drilling in metal, wood, and plastics. It measures 0.0550 inches in diameter with an overall length of 1-7/8 inches and a flute length of 7/8 inch. The bit is ground from high speed steel and left in a bright, uncoated finish. The 118-degree standard point angle and web-thinned, tapered web geometry allow clean entry and reduce the thrust required to start a hole. Two spiral flutes evacuate chips efficiently during through-hole and blind-hole work. This bit is installed by machinists, maintenance mechanics, sheet metal workers, and general tradespeople working with hand drills, drill presses, and CNC equipment.

The C72154 is suited for light-duty drilling applications where a small-diameter, close-tolerance hole is required. The straight-cylindrical shank seats in standard drill chucks without adapters. The 4xD flute-to-diameter ratio supports adequate chip clearance at this diameter. With a diameter tolerance of -0.0005 to 0.0000 inches, the bit holds a consistent hole size appropriate for tap drilling, clearance holes, and precision layout work across general manufacturing, fabrication, and service environments.

Key Features

• Wire gauge size 54, 0.0550-inch diameter with tight tolerance of -0.0005 to 0.0000 inches
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High speed steel construction with bright, uncoated finish for general-purpose use
• Right-hand cut, two-flute regular spiral for efficient chip evacuation
• Straight-cylindrical shank at 0.0550 inches diameter, 1.0000-inch shank length, fits standard chucks
• Conforms to ASME B94.11M and DIN 338 standards

Compatibility

Designed as a general-purpose jobber length drill bit in the CLEVELAND Series 2002G, compatible with any standard drill chuck that accepts a straight-cylindrical shank at 0.0550 inches diameter.

Installation Notes

Secure the shank fully in the drill chuck before operation and verify concentricity to prevent bit deflection at this small diameter. Use appropriate cutting fluid for harder materials to extend edge life. Always wear eye protection when operating rotary cutting tools. Inspect the bit for chipping or breakage before each use, as small-diameter bits are susceptible to fracture under side loading or excessive feed pressure.
