Cleveland C14825 Screw Machine Drill Bit 4.1mm Cobalt

Product Description

The CLEVELAND C14825 is a screw machine length drill bit designed for high-production drilling in metalworking applications. Built from M42 cobalt high-speed steel, this bit handles tough alloy steels, aluminum, and other demanding workpiece materials without losing edge integrity under heat. The 135-degree split point geometry reduces walking at entry and lowers the thrust force needed to start a hole, making it well suited for production environments where speed and precision matter. The web-thinned, parallel-web construction further reduces cutting resistance. At 55 mm overall length, the short, rigid body minimizes deflection and chatter during drilling.

This drill bit is used in screw machine shops, CNC machining centers, drill press operations, and general metalworking where a compact, stiff bit is preferred over jobber length. The straight-cylindrical shank seats directly in standard drill chucks and collets. Primary workpiece materials include alloy steel and aluminum, making it a practical choice for production shops running mixed-metal jobs. The right-hand cut, two-flute spiral design clears chips efficiently throughout the 22 mm flute length.

Key Features

• M42 cobalt construction for extended tool life in alloy steel and aluminum
• 135-degree split point reduces drill walking and lowers entry thrust
• Web-thinned, parallel-web design minimizes cutting resistance
• Screw machine length body provides maximum rigidity and reduced deflection
• Right-hand cut, two-flute spiral flute for efficient chip evacuation
• Meets ASME B94.11M and DIN 1897 standards

Compatibility

Designed for use in standard drill chucks and collets accepting a 0.1614-inch straight-cylindrical shank. Suitable for drilling alloy steel and aluminum workpieces in screw machine and general machining setups.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable tolerance. Always power down and lock out the machine before changing tooling. Do not exceed the recommended speed and feed range for the workpiece material and bit diameter.
