Cleveland C14814 9mm Cobalt Screw Machine Drill Bit

Product Description

The CLEVELAND C14814 is a cobalt screw machine length drill bit designed for high-performance drilling in demanding metalworking applications. Built to ASME B94.11M and DIN 1897 standards, this heavy-duty bit measures 9 mm (0.3543 inches) in diameter with an overall length of 3.307 inches and a 135-degree split point for fast, accurate starting without a center punch. The M42 cobalt construction provides heat resistance and edge retention when cutting through tough materials. The web-thinned, parallel web configuration reduces thrust and improves chip flow. Machinists, tool-and-die workers, and maintenance technicians install this type of bit in drill presses, CNC machines, and hand-held drilling equipment.

This bit is rated for use on alloy steel and aluminum workpieces, making it well suited for production drilling, fabrication shops, and MRO environments where tool life under heat is a priority. The screw machine length body keeps the bit rigid and minimizes deflection in short-reach setups, which is a common requirement on turret lathes, drill presses, and screw machines. The straight-cylindrical shank with a diameter of 0.3543 inches fits standard three-jaw chucks and collet holders used in those applications.

Key Features

• M42 cobalt construction for heat resistance and extended tool life in hard and abrasive materials
• 135-degree split point reduces walking and lowers thrust force at entry
• Web-thinned parallel web improves chip evacuation and reduces cutting resistance
• Screw machine length body increases rigidity and minimizes deflection in short-reach setups
• Right-hand spiral flutes with 1.575 inches of flute length promote consistent chip clearing
• Meets ASME B94.11M and DIN 1897 standards; diameter tolerance held to +0.0000 to -0.0010 inches

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for metalworking applications requiring a 9 mm straight-shank screw machine length drill bit compatible with standard three-jaw chucks and collet systems. Suitable for workpiece materials including alloy steel and aluminum per Cleveland Series 2133 specifications.

Installation Notes

This bit is installed by machinists and toolroom technicians in drill presses, lathes, and CNC drilling equipment. Secure the straight-cylindrical shank fully in the chuck or collet before operation and verify runout before cutting production parts. Use appropriate cutting fluid for alloy steel to preserve edge life. Follow all machine guarding requirements and wear eye protection per shop safety standards.
