Cleveland C04622 5/8 Inch Screw Machine Drill Bit Hss

Product Description

The CLEVELAND C04622 is a screw machine length (stub) drill bit designed for high-speed steel general-purpose drilling. It features a 5/8-inch diameter, a 118-degree standard point angle, and a bright/uncoated finish. The short overall length of 4.25 inches and the straight-cylindrical shank make it well suited for drill presses, milling machines, and CNC machining centers where rigidity and reduced runout are required. Web-thinned construction reduces thrust and improves chip evacuation during drilling operations.

This bit is intended for use on alloy steels and aluminum in production and maintenance environments. Its screw machine length profile — shorter than a jobber bit — provides added stiffness, making it a practical choice for applications where hole location accuracy and tool deflection control are priorities. The two-flute spiral design with a regular helix handles both ferrous and non-ferrous materials across general shop and field machining tasks.

Key Features

• 5/8-inch (0.6250 inch) diameter with a diameter tolerance of +0.0000 to -0.0012 inches for consistent hole sizing
• 118-degree standard point angle with web-thinned, parallel web geometry for reduced entry thrust
• High-speed steel construction provides durability across general-purpose ferrous and non-ferrous applications
• Bright/uncoated finish — no coating buildup to affect shank fit or dimensional accuracy
• Straight-cylindrical shank at 0.6250 inches diameter fits standard drill chucks without adapters
• Complies with ASME B94.11M standards for screw machine length drill geometry

Compatibility

Designed as a general-purpose screw machine length drill bit suitable for use in drill presses, knee mills, machining centers, and hand-held drill motors with a compatible 5/8-inch capacity chuck. Primary workpiece materials include alloy steel and aluminum per manufacturer specification.

Installation Notes

Installation and use should be performed by a qualified machinist or tradesperson familiar with rotating cutting tools. Secure the shank fully in the chuck to the depth recommended by the chuck manufacturer before beginning a cut. Always power down and lock out the machine before changing or inspecting the bit. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, noting that this bit does not support coolant-through delivery.
