Cleveland C08593 Taper Length Drill Bit Size 60 Hss

Product Description

The CLEVELAND C08593 is a taper length drill bit designed for precision drilling in metal fabrication and general machining applications. Built from high-speed steel with a coated finish, this bit features a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. It carries a wire gauge size of 60, corresponding to a decimal diameter of 0.0400 inches. The spiral flute design and right-hand cut make it compatible with standard drill presses and handheld power tools used by machinists, maintenance technicians, and tool and die professionals.

This drill bit is suited for drilling alloy steel, carbon steel, and cast iron in general-purpose production and maintenance environments. The taper length body provides additional reach compared to jobber-length bits, making it useful in applications where clearance or depth requires a longer flute. It conforms to ASME B94.11M and DIN 340 standards, fitting into workflows that demand dimensional consistency. The straight shank seats directly into standard drill chucks without adapters.

Key Features

• Wire gauge size 60, 0.0400 inch decimal diameter with a tolerance of +0.0000 to -0.0005 inches
• 118-degree standard point angle for general-purpose drilling in ferrous metals
• High-speed steel construction with coated finish for improved wear resistance
• Web-thinned tapered web reduces cutting resistance and thrust load
• Right-hand spiral flute with regular spiral type for efficient chip removal
• Meets ASME B94.11M and DIN 340 standards for dimensional accuracy

Compatibility

Rated for use in alloy steel, carbon steel, and cast iron. Designed as a general-purpose replacement or stock bit for standard drill chucks accepting a 0.0400 inch straight shank.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard drill press or power drill with a compatible chuck. Ensure the workpiece is securely clamped before drilling and that the drill is running at a speed appropriate for the material and bit diameter. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is observed. Follow applicable shop safety protocols for rotating tool operation.
