Cleveland C04663 Screw Machine Drill Bit 61/64 in Hss

Product Description

The CLEVELAND C04663 is a screw machine length (stub length) drill bit designed for high-production drilling in metal fabrication, maintenance, and machining environments. Built from high-speed steel with a bright/uncoated finish, it features a 118-degree standard point angle and a web-thinned tip that reduces thrust and improves penetration in harder materials. The 61/64 inch diameter (0.9531 inches decimal) and short overall length of 5-7/8 inches make this bit well-suited for drill press and hand-held power tool applications where rigidity matters. The straight-cylindrical shank seats securely in standard chucks. This bit conforms to ASME B94.11M standards.

The C04663 is a general-purpose drill bit suited for drilling into alloy steel, aluminum, and similar workpiece materials. Its short screw machine length profile reduces deflection and improves hole accuracy in production settings, repair shops, and field service work. The 2-flute spiral design provides efficient chip evacuation during through-hole and blind-hole drilling. This bit is appropriate for use on drill presses, CNC drilling stations, and standard electric drill drivers where chuck capacity allows the 61/64 inch shank diameter.

Key Features

• 118-degree standard point angle with web thinning for reduced entry thrust
• High-speed steel construction for durability across general-purpose metal drilling
• Short screw machine length overall length of 5-7/8 inches for increased rigidity and reduced deflection
• 2-flute regular spiral design for efficient chip removal
• Straight-cylindrical shank compatible with standard drill chucks
• Conforms to ASME B94.11M standards

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with drill presses, CNC drilling equipment, and hand-held power drills equipped with chucks sized to accept a 0.9531-inch straight-cylindrical shank. Suitable for drilling alloy steel and aluminum workpieces.

Installation Notes

Secure the shank fully in the chuck and verify chuck key is removed before starting the machine. Power down or unplug the drill or press before changing bits. Wear appropriate eye and hand protection when operating. Follow applicable shop safety standards and manufacturer guidance for feed rate and speed selection based on workpiece material.
