Cleveland C04489 Screw Machine Drill Bit Wire 3 Hss

Product Description

The CLEVELAND C04489 is a screw machine length drill bit designed for general-purpose drilling in production and job-shop environments. Built from high-speed steel with a bright uncoated finish, this wire gauge number 3 bit measures 0.2130 inches in diameter with a 118-degree standard point angle. The short overall length of 2.375 inches provides increased rigidity and reduced deflection when drilling in drill presses, CNC lathes, turret lathes, and screw machines. The web-thinned, parallel web construction reduces thrust and improves chip evacuation. Machinists, toolroom technicians, and production operators install this bit for repetitive hole-making operations where consistent accuracy and tool life matter.

This drill bit is suited for use in screw machines, turret lathes, and short-setup drilling fixtures where a stub-length tool is preferred over a jobber-length bit. Primary workpiece materials include alloy steels and aluminum. The 118-degree standard point is appropriate for a wide range of metal drilling applications. The straight cylindrical shank with a diameter of 0.2130 inches is compatible with standard drill chucks and collet holders sized for that shank. The two-flute spiral design with regular helix handles chip clearance in through-hole and blind-hole applications across general manufacturing and maintenance settings.

Key Features

• 118-degree standard point angle with web thinning to reduce drilling thrust
• High-speed steel construction for general-purpose metal cutting
• Short screw machine length overall length of 2.375 inches for improved rigidity
• Straight cylindrical shank diameter of 0.2130 inches for standard chuck compatibility
• Right-hand cut with two-flute spiral configuration for consistent chip evacuation
• Conforms to ASME B94.11M standards

Compatibility

Designed as a general-purpose screw machine length drill bit for use with standard drill chucks and collet holders sized for a 0.2130-inch straight cylindrical shank, compatible with drill presses, CNC lathes, turret lathes, and screw machines drilling alloy steel and aluminum workpieces.

Installation Notes

This bit is installed by machinists and toolroom technicians in drill chucks or collet holders rated for the 0.2130-inch shank diameter. Ensure the machine spindle is fully stopped and power is locked out before changing tooling. Verify chuck or collet runout is within acceptable limits to maintain the stated diameter tolerance. Do not exceed the recommended feed and speed parameters for the workpiece material and machine type.
