Cleveland C04418 7/64 Inch Screw Machine Drill Bit Hss

Product Description

The CLEVELAND C04418 is a screw machine length (stub) drill bit designed for high-volume drilling operations where rigidity and precision matter. Manufactured from high-speed steel with a bright/uncoated finish, this bit measures 7/64 inches (0.1094 inches) in diameter with an overall length of 1-13/16 inches and a flute length of 13/16 inches. The 118-degree standard point angle and web-thinned tip geometry reduce thrust force at entry and improve centering on the workpiece. The shorter-than-standard body length increases rigidity, minimizes deflection, and is well suited to drill press, CNC, and screw machine applications. Machinists, tool and die workers, and general maintenance techs are the typical users.

This bit is used in production machining, fabrication shops, and maintenance environments where short, stiff tooling is preferred over jobber-length bits. The straight-cylindrical shank fits standard drill chucks without modification. Primary workpiece materials listed by the manufacturer include alloy steel and aluminum. The 2-flute right-hand spiral design provides efficient chip evacuation in both ferrous and non-ferrous materials. General-purpose grade tooling at this diameter range (0.1000 to 0.1500 inches decimal) is common for tapping prep, clearance holes, and pilot drilling.

Key Features

• 7/64 inch diameter (0.1094 inches decimal) with diameter tolerance of +0.0000 to -0.0005 inches for consistent fit
• 118-degree standard point angle with web-thinned tip for reduced entry thrust
• High-speed steel construction for general-purpose performance across alloy steel and aluminum
• Screw machine (short) length body at 1-13/16 inches OAL increases rigidity and reduces deflection
• Straight-cylindrical shank compatible with standard drill chucks
• Bright/uncoated finish; right-hand cut with regular spiral flutes for efficient chip clearing

Compatibility

Designed as a general-purpose screw machine length drill bit suitable for standard drill chucks, drill presses, CNC machining centers, and screw machine setups where a straight-cylindrical shank is required. Confirmed workpiece materials include alloy steel and aluminum per manufacturer specifications.

Installation Notes

Installation and use should be performed by machinists or qualified trades personnel familiar with rotating cutting tools. Secure the straight-cylindrical shank firmly in a properly sized chuck before operation and verify runout before beginning a production run. Always wear appropriate eye protection and follow shop safety procedures when operating drilling equipment. Refer to ASME B94.11M for dimensional standards governing this bit series.
