Cleveland C14204 1/8 Inch Cobalt Screw Machine Drill Bit

Product Description

The CLEVELAND C14204 is a cobalt screw machine length drill bit designed for high-performance drilling in demanding production and maintenance environments. Built from M42 cobalt high-speed steel, it delivers heat and wear resistance needed when cutting through tough alloy steels, stainless, and hard metals. The bit measures 1/8 inch (0.1250 inches) in diameter with a 1-7/8 inch overall length and features a 135-degree split point that reduces walking and cutting pressure at entry. The parabolic flute geometry promotes efficient chip evacuation. This bit is typically installed by machinists, maintenance mechanics, and metal fabricators using standard drill presses, CNC machines, or hand drills.

The C14204 is suited for screw machine, production drilling, and general metalworking applications. Its stub-length design provides increased rigidity compared to jobber-length bits, making it effective in tight-clearance setups or fixture-guided operations. Primary workpiece materials include alloy steel and aluminum. The right-hand cutting direction and straight-cylindrical shank allow direct chuck mounting without adapters. The 7/8 inch flute length accommodates the shallow hole depths typical of screw machine work.

Key Features

• M42 cobalt construction for heat resistance during high-speed or dry cutting operations
• 135-degree split point reduces thrust force and eliminates the need for a center punch on most metals
• Parabolic flute design promotes fast chip clearing and reduces clogging in deeper passes
• Web-thinned, parallel web configuration lowers cutting resistance and extends tool life
• Screw machine (stub) length provides added rigidity versus standard jobber bits
• Diameter tolerance of +0.0000 to -0.0005 inches ensures close-tolerance hole sizing

Compatibility

Designed as an OEM-style screw machine drill bit for use in standard drill chucks, CNC turrets, and screw machine tooling setups that accept a 0.1250-inch straight-cylindrical shank. Conforms to ASME B94.11M and ANSI specification designation.

Installation Notes

This bit is installed by machinists and metal fabricators in drill presses, turret lathes, CNC machining centers, or hand drills equipped with a compatible chuck. Secure the shank fully in the chuck and confirm concentricity before operation. Always power down and lock out the machine before changing tooling. Use appropriate cutting fluid for alloy steel applications to preserve tool life and maintain hole quality.
