Cleveland C14523 Screw Machine Drill Bit Size 52 Cobalt

Product Description

The CLEVELAND C14523 is a screw machine length drill bit designed for high-speed drilling in demanding metalworking applications. Built from M42 cobalt high-speed steel, this bit handles tough alloy steels and aluminum with consistent performance. The 135-degree split point reduces walking on entry and lowers thrust required to begin the cut. At 0.0635 inches in diameter (wire size 52) with an overall length of 1-11/16 inches, the short flute length adds rigidity and minimizes deflection. This bit is suited for production environments where hole quality and tool life under heat and pressure are priorities. Licensed machinists, tool and die technicians, and production floor operators are the typical end users.

This drill bit is built for screw machine work, CNC drilling operations, and bench drill press applications where a stubby, rigid bit is preferred over jobber-length alternatives. It performs well in alloy steel and aluminum workpieces. The straight cylindrical shank fits standard drill chucks without adapters. With a regular spiral and parallel web configuration, chip evacuation stays consistent across short-run and production-volume drilling cycles.

Key Features

• M42 cobalt construction for heat resistance and extended tool life in hard metals
• 135-degree split point reduces entry walking and lowers axial thrust
• Web-thinned parallel web improves chip flow and reduces torque demand
• Screw machine (stub) length adds rigidity and reduces deflection in tight setups
• Right-hand cut, 2-flute spiral design for standard drilling operations
• Meets ASME B94.11M and DIN 1897 (ANSI and DIN) standards

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for standard drill chucks accepting a 0.0635-inch straight cylindrical shank in screw machine, CNC, or bench drill press applications.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or tool operators familiar with drill press and CNC setup procedures. Ensure the drill chuck is fully secured and the workpiece is clamped before beginning any drilling operation. Do not exceed the recommended speed and feed parameters for the workpiece material. Inspect the bit for wear or chipping before each use, as cobalt bits used beyond their service life can produce out-of-tolerance holes.
