Cleveland C71159 Jobber Drill Bit Wire 59 0.0410 in Hss

Product Description

The CLEVELAND C71159 is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastics. Manufactured from high-speed steel with an oxide coating for improved lubricity and corrosion resistance, it cuts a 0.0410-inch diameter hole using a standard 118-degree split point and a web-thinned tip that reduces walking on entry. The straight-cylindrical shank seats securely in standard drill chucks. At 1.625 inches overall length with a 0.688-inch flute, this bit is a compact, reliable choice for production drilling and maintenance work performed by machinists, pipefitters, electricians, and general tradespeople.

The C71159 is suited for light-duty hole-making tasks where a wire-gauge No. 59 diameter is required. Common applications include pilot holes, tap-drill operations for small-thread fasteners, and precision layout work on sheet metal or thin-stock components. The regular spiral flute provides efficient chip evacuation in shallow-depth passes. This bit is sold individually and is typically used in benchtop drill presses, hand drills, and CNC drill stations running at appropriate spindle speeds for high-speed steel tooling.

Key Features

• Wire gauge No. 59 drill size — 0.0410-inch diameter for tight-tolerance hole requirements
• High-speed steel construction handles general-purpose drilling across common materials
• Oxide finish improves surface lubricity and provides basic corrosion protection
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• Regular spiral, 2-flute design promotes consistent chip clearance
• Meets ASME B94.11M and DIN 338 standards for jobber-length drill bits

Compatibility

Designed as a general-purpose jobber-length drill bit in the Cleveland Series 2001G, compatible with any standard drill chuck accepting a 0.0410-inch straight-cylindrical shank.

Installation Notes

A licensed machinist or qualified tradesperson should verify correct spindle speed for high-speed steel tooling before use. Secure the workpiece firmly before drilling to prevent rotation or shifting. For small-diameter bits of this size, apply light, consistent feed pressure to avoid bit breakage. No coolant-through capability is present on this bit; use cutting fluid applied externally when drilling harder metals.
