Cleveland C04376 Screw Machine Drill Bit 1/16 in Hss

Product Description

The CLEVELAND C04376 is a screw machine length (stub-length) drill bit designed for general-purpose drilling in tight clearance applications. Made from high-speed steel (HSS) with a bright, uncoated finish, it measures 1/16 inch (0.0625 inch) in diameter and carries a standard 118-degree point angle. The short overall length of 1-5/8 inches increases rigidity and reduces deflection compared to jobber-length bits, making it well-suited for production drilling and machine work. Two spiral flutes provide chip evacuation, and the web-thinned design reduces thrust during entry. This bit is part of the Series 2120 line and conforms to ASME B94.11M standards.

The C04376 is used in drill presses, CNC machining centers, turret lathes, and screw machines where short, rigid tooling is required. Primary workpiece materials include alloy steel and aluminum. The straight-cylindrical shank seats directly into standard drill chucks and collets. This bit is appropriate for general-purpose metalworking in light manufacturing, maintenance, and trade shop environments where high cycle counts demand consistent, repeatable hole geometry at small diameters.

Key Features

• Screw machine (stub) length at 1-5/8 inches overall for increased rigidity and reduced deflection
• High-speed steel construction suitable for alloy steel and aluminum workpieces
• 118-degree standard point angle with web-thinned tip to reduce entry thrust
• Bright, uncoated finish — no coating buildup to affect tight diameter tolerance of +0.0000 to -0.0005 inch
• Right-hand cut with two spiral flutes for efficient chip removal
• Conforms to ASME B94.11M and ANSI specification standards

Compatibility

Designed as a general-purpose screw machine length drill bit for use in standard drill chucks and collets accepting a 1/16 inch straight-cylindrical shank. Suitable for drill presses, turret lathes, CNC machining centers, and hand-held electric drills used in metalworking applications.

Installation Notes

Installation and use should be performed by machinists or qualified trade personnel familiar with rotating cutting tools. Secure the shank fully in the chuck or collet before operation and confirm the workpiece is clamped or fixtured. Cutting speeds and feeds should follow published HSS guidelines for the target material. Always wear appropriate eye protection and ensure the spindle is fully stopped before changing tooling.
