Cleveland C14205 Screw Machine Drill Bit 9/64 in Cobalt

Product Description

The CLEVELAND C14205 is a screw machine length drill bit designed for high-performance drilling in demanding shop and field applications. Built from M42 cobalt high-speed steel, it delivers extended tool life when cutting through alloy steels, stainless, aluminum, and other tough materials that wear out standard HSS bits. The 135-degree split point starts on contact without a center punch, reducing walking and improving positional accuracy. At 9/64 inch (0.1406 inch decimal) diameter and 1-15/16 inches overall length, this stub-length bit provides added rigidity compared to jobber-length alternatives, making it a solid choice for production drilling and tight-clearance setups.

The C14205 fits standard drill presses, CNC machining centers, hand drills, and right-angle drivers used in fabrication shops, HVAC ductwork work, plumbing rough-in, and general metalworking. Its screw machine length profile is well suited to production environments where rigidity and repeatability matter. The straight-cylindrical shank seats cleanly in standard 3-jaw chucks. Primary workpiece materials listed by the manufacturer include alloy steel and aluminum.

Key Features

• M42 cobalt construction for heavy-duty cutting in hard and abrasive metals
• 135-degree split point with web thinning reduces thrust and eliminates need for center punching
• Parabolic flute geometry promotes efficient chip evacuation
• Screw machine (stub) length adds rigidity and reduces deflection versus jobber-length bits
• Right-hand cut with straight-cylindrical shank for universal chuck compatibility
• Meets ASME B94.11M and ANSI specification designations

Compatibility

Designed as a direct-fit screw machine length drill bit for use in standard 3-jaw chucks and collet holders accepting a 0.1406 inch straight-cylindrical shank across drill presses, CNC equipment, and handheld power drills.

Installation Notes

Installation and use should be performed by machinists or qualified tradespeople familiar with rotating cutting tools. Secure the shank fully in the chuck and verify runout before drilling. Always wear appropriate eye protection and ensure the workpiece is firmly clamped before engaging the bit. Follow shop safety protocols and applicable OSHA standards when operating drilling equipment.
