Cleveland C04455 Screw Machine Drill Bit Wire 19 Hss

Product Description

The CLEVELAND C04455 is a screw machine length (stub length) drill bit designed for general-purpose drilling in metalworking and fabrication applications. Built from high-speed steel (HSS) with a bright/uncoated finish, this bit carries a wire gauge size of 19, equal to 0.1660 inches in decimal. The 118-degree standard point angle and web-thinned tip reduce thrust and improve centering at the start of a cut. Overall length is 2.125 inches, making it shorter and more rigid than jobber-length bits — a practical advantage when drilling in tight clearances or on drill presses where rigidity matters.

This bit is suited for drilling alloy steel, aluminum, and similar workpiece materials in production and maintenance environments. The straight-cylindrical shank fits standard drill chucks without adapters. At 2.125 inches overall with a 1.0625-inch shank and a 1.0625-inch flute length, the compact geometry is well-matched to screw machine operations, turret lathes, and short-stroke drill press work. It is a regular-spiral, two-flute design appropriate for general machining tasks where chip evacuation and hole quality are both priorities. This bit conforms to ASME B94.11M standards.

Key Features

• Wire size 19 (0.1660 inches decimal) — precise sizing for production drilling work
• 118-degree standard point with web thinning for reduced entry thrust and improved centering
• High-speed steel construction rated for general-purpose cutting in alloy and aluminum
• Bright/uncoated finish — suitable for use with cutting fluids or dry
• Short screw machine length (2.125 inches OAL) for increased rigidity over jobber-length bits
• Straight-cylindrical shank fits standard three-jaw drill chucks directly
• Conforms to ASME B94.11M standard for drill bit geometry and tolerances

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with any standard drill chuck accepting a 0.1660-inch straight-cylindrical shank, including drill presses, turret lathes, and CNC screw machines.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with rotating cutting tools. Secure the shank fully in the drill chuck and verify runout before beginning a cut. Always power down and lock out the machine before changing bits. Follow applicable shop safety standards and manufacturer guidelines for feeds, speeds, and cutting fluid selection based on workpiece material.
