Cleveland C72159 Jobber Drill Bit Wire 59 Hss 118

Product Description

The CLEVELAND C72159 is a jobber-length drill bit sized to wire gauge 59, with a decimal diameter of 0.0410 inches. Built from high speed steel with a bright, uncoated finish, it delivers reliable performance in general-purpose drilling applications. The 118-degree standard point angle and web-thinned tip reduce entry force and walking on flat or curved surfaces. Two spiral flutes with a regular helix clear chips efficiently during through-hole drilling. At 1.625 inches overall length with a straight-cylindrical shank, this bit is compatible with standard drill chucks and is sold individually.

This bit is suited for light-duty production and maintenance drilling in metal, plastic, and similar materials. The wire size 59 diameter targets small-hole applications common in tool and die work, electronics assembly, plumbing, and HVAC sheet metal fabrication. The 11/16-inch flute length and 4xD flute-to-diameter ratio allow adequate chip evacuation in short, shallow holes typical for this diameter range. Licensed trades including electricians, HVAC technicians, and plumbers regularly use bits in this size range for pilot holes, knockout starts, and precision location drilling.

Key Features

• Wire gauge size 59 — 0.0410-inch decimal diameter for precision small-hole drilling
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust
• High speed steel construction for durability across metals and plastics
• Bright uncoated finish — no coating buildup to affect diameter tolerance
• Right-hand cut with regular spiral flutes for consistent chip ejection
• Meets ASME B94.11M and DIN 338 standards

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard drill chucks accepting straight-cylindrical shanks in the 0.0410-inch diameter range.

Installation Notes

Installation of this bit requires a drill press, hand drill, or similar rotating tool with a chuck sized to accept a 0.0410-inch straight shank. Secure the shank fully in the chuck jaws before applying power. Use appropriate cutting fluid when drilling ferrous metals to extend tool life. Always wear eye protection and secure the workpiece to prevent rotation during drilling.
