Cleveland C15050 Cobalt Screw Machine Drill Bit 1/16 in

Product Description

The CLEVELAND C15050 is a screw machine length cobalt drill bit designed for high-performance drilling in demanding materials. Built from M42 cobalt steel, it delivers superior heat and wear resistance compared to standard high-speed steel bits. The 135-degree split point reduces walking and lowers thrust requirements, allowing cleaner entry without a center punch in most applications. With a 1/16-inch diameter and a compact 1-5/8-inch overall length, this bit is suited for precision drilling in tight spaces. The parabolic flute geometry improves chip evacuation, reducing clogging during deeper passes. Licensed machinists, HVAC technicians, and plumbers reach for this bit when drilling through alloy steel, aluminum, and similar materials.

The C15050 is built for production drilling environments where cycle time and tool life matter. The screw machine length format gives a shorter, more rigid profile than jobber-length bits, reducing deflection when working in drill presses, CNC machines, or tight hand-drill applications. Its straight cylindrical shank fits standard chucks and collets without modification. The web-thinned, parallel-web design maintains bit rigidity while reducing cutting force. Primary workpiece materials include alloy steel and aluminum, making this bit a reliable choice for mechanical, HVAC, and plumbing rough-in and fabrication tasks.

Key Features

• M42 cobalt tool material provides high heat resistance for cutting tough alloys
• 135-degree split point reduces drill walking and lowers required feed pressure
• Parabolic flute design promotes efficient chip evacuation
• Web-thinned construction reduces cutting resistance and extends tool life
• Screw machine length body offers a rigid, low-deflection profile
• Meets ASME B94.11M standard for drill bit geometry and tolerances

Compatibility

Designed as an OEM-style replacement screw machine drill bit for use with standard drill presses, CNC equipment, and hand drills accepting a 1/16-inch straight cylindrical shank.

Installation Notes

Installation should be performed by qualified machinists or trade professionals familiar with rotary cutting tools. Secure the shank firmly in a compatible chuck or collet before operating. Always wear appropriate eye protection and follow shop or jobsite safety protocols when operating drilling equipment. Inspect the cutting edges for wear or chipping before each use and replace the bit if the geometry is compromised.
