Cleveland C14244 Screw Machine Drill Bit Cobalt M42

Product Description

The CLEVELAND C14244 is a cobalt M42 screw machine length drill bit designed for high-performance drilling in demanding trade and industrial applications. Built to wire size 4 (0.2090 inches diameter), this bit features a 135-degree split point for fast, self-centering starts with minimal walking. The parabolic flute geometry promotes efficient chip evacuation, and the oxide straw coating provides added lubricity and surface protection. At 2-3/8 inches overall length, the stub-length body delivers maximum rigidity and reduced deflection in tight drilling situations. This is a heavy-duty grade bit suitable for machinists, pipefitters, and maintenance technicians who drill through tough materials regularly.

This drill bit is engineered for use across a wide range of workpiece materials including aluminum, brass, carbon steel, cast iron, nickel alloy, plastics, stainless steel, and tool steel. Its screw machine (stub) length makes it well suited for drill press work, CNC setups, and hand-held drilling in confined spaces where a jobber-length bit would flex or bind. The straight-cylindrical shank fits standard drill chucks without adapters. The web-thinned, parallel web configuration reduces thrust requirements when drilling hard alloys and stainless.

Key Features

• Cobalt M42 tool material for heat and wear resistance in hard and abrasive materials
• 135-degree split point for self-centering starts and reduced thrust
• Parabolic flute design promotes fast chip evacuation and reduced heat buildup
• Oxide straw coating adds lubricity and corrosion resistance
• Web-thinned parallel web lowers cutting force in tough alloys
• Screw machine (stub) length provides maximum rigidity and reduced deflection

Compatibility

Designed as an OEM-style replacement or direct drop-in for screw machine length cobalt drill bits of equivalent wire size 4 (0.2090 inches) diameter with a straight-cylindrical shank, conforming to ANSI specification standards. Compatible with standard drill chucks on drill presses, CNC machines, and portable power drills.

Installation Notes

Installation and use should be performed by qualified machinists or experienced tradespeople familiar with proper drilling procedures. Ensure the drill chuck is fully tightened and the workpiece is securely clamped or fixtured before drilling. Apply appropriate cutting fluid when drilling stainless steel, nickel alloys, or tool steel to extend bit life and manage heat. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
