Cleveland C08605 Taper Length Drill Bit Wire 55 Hss

Product Description

The CLEVELAND C08605 is a taper length, straight-shank drill bit engineered for general-purpose drilling in ferrous metals and cast materials. Built from high-speed steel with an oxide coating, it carries a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces thrust and improves chip clearance at the cutting edge. Wire size 55 corresponds to a decimal diameter of 0.0520 inches. The right-hand spiral flute and taper length body make this bit well suited for production drilling and maintenance applications where a standard jobber length would be too short for the depth required. Licensed machinists and industrial maintenance technicians are the primary users.

This drill bit is rated for use in alloy steel, carbon steel, and cast iron. The taper length design provides additional reach compared to a jobber-length bit of the same diameter, making it a practical choice for drilling deeper holes without extension tooling. The oxide finish provides a basic level of lubricity and mild corrosion resistance during storage and in-cut use. At 0.0520 inches in diameter, this bit fits applications requiring tight, small-diameter through-holes in metal plate, brackets, and structural components. It is sold individually but subject to a minimum order quantity of 10 units.

Key Features

• Wire size 55 diameter: 0.0520 inches with a tolerance of +0.0000 to -0.0005 inches
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High-speed steel construction with oxide coating for basic lubricity and corrosion resistance
• Right-hand cut with regular spiral flute geometry for efficient chip evacuation
• Taper length body: 1.75-inch flute length and 3-inch overall length for extended reach
• Straight shank compatible with standard drill chucks

Compatibility

Rated for drilling in alloy steel, carbon steel, and cast iron. Designed as a general-purpose taper length drill bit for use in standard drill chucks accepting straight shanks at this diameter range.

Installation Notes

This bit is installed and operated by machinists, toolroom technicians, or industrial maintenance personnel using drill presses, CNC machines, or handheld power drills with compatible chucks. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before beginning any drilling operation. Use appropriate cutting fluid for the material being drilled to extend tool life and maintain hole tolerance. Inspect the cutting edges for wear before each use; a worn or chipped point will produce oversized or out-of-tolerance holes.
