Cleveland C71104 Jobber Drill Bit Wire 4 0.2090 Hss

Product Description

The CLEVELAND C71104 is a jobber length drill bit designed for general-purpose hole-making in metal, wood, and plastics. Built from high speed steel with an oxide coating, this bit handles a wide range of shop and field drilling tasks without specialized coolant. It carries a wire gauge size of 4, equivalent to 0.2090 inches in decimal diameter. The 118-degree standard point angle and web-thinned, tapered web construction reduce entry force and improve chip evacuation. With a 2-flute spiral flute design and right-hand cutting direction, it is a straightforward workhorse for machinists, maintenance technicians, and fabricators who need reliable, repeatable hole quality.

This bit fits naturally into metal fabrication, HVAC sheet metal work, electrical panel installation, plumbing rough-in, and general maintenance applications. Its straight-cylindrical shank seats securely in standard 3-jaw keyless or keyed drill chucks. The Series 2001G designation follows ASME B94.11M and DIN 338 standards, making it a direct fit for shops and service trucks that stock to those specifications. Overall length of 3.75 inches keeps it compact enough for close-quarters drilling while providing adequate flute length for chip clearance at depth.

Key Features

• Wire size 4 diameter: 0.2090 inches, tolerance -0.0007 to 0.0000 inches for consistent hole sizing
• High speed steel construction with oxide coating for corrosion resistance and reduced friction
• 118-degree standard point angle with web-thinned, tapered web for easier bit entry
• 2-flute regular spiral design promotes efficient chip removal during drilling
• Right-hand cut, straight-cylindrical shank fits standard drill chucks without adapters
• Meets ASME B94.11M and DIN 338 standards for jobber length drill bits

Compatibility

Designed as a general-purpose jobber length drill bit for use in standard 3-jaw keyed or keyless drill chucks that accept a 0.2090-inch straight-cylindrical shank. Suitable for hand drills, drill presses, and milling machine setups where a wire gauge size 4 hole is required.

Installation Notes

Secure the straight-cylindrical shank fully in the chuck before drilling and verify the chuck is tightened to prevent slippage. Always wear appropriate eye protection and secure the workpiece to prevent rotation. Use cutting fluid on ferrous metals to extend bit life and improve hole finish. Inspect the cutting edges for wear before each use; a dull bit increases thrust load and can cause workpiece damage or bit breakage.
