Cleveland C14260 Screw Machine Drill Bit 20 Cobalt

Product Description

The CLEVELAND C14260 is a screw machine length drill bit designed for high-performance metal drilling in demanding trade and industrial applications. Built from M42 cobalt high-speed steel, this bit handles hard and abrasive materials where standard HSS tooling fails. The 135-degree split point reduces walking and cutting thrust, allowing faster starts without a center punch. A parabolic flute design improves chip evacuation, reducing heat buildup and extending tool life. The straight-cylindrical shank measures 0.1610 inches in diameter and is compatible with standard drill chucks. The overall length of 2.125 inches makes this a compact, rigid choice for close-tolerance drilling in tight spaces.

This bit is suited for drilling alloy steel and aluminum in screw machine, production, and general machining environments. Its screw machine (stub) length provides added rigidity compared to jobber-length bits, reducing deflection in high-RPM applications. Machinists, tool-and-die technicians, and maintenance professionals use this style of bit in drill presses, screw machines, CNC equipment, and handheld power drills where a short, stiff cutting tool is required.

Key Features

• M42 cobalt construction handles hard alloys and abrasive materials
• 135-degree split point reduces walking and lowers required feed force
• Parabolic flute geometry accelerates chip evacuation and reduces heat
• Web-thinned, parallel web construction extends cutting edge durability
• Screw machine length provides superior rigidity over jobber-length bits
• Meets ASME B94.11M and ANSI specification standards

Compatibility

Designed as a direct-fit replacement or addition for applications requiring a wire size 20 (0.1610 inch) screw machine length drill bit in standard straight-cylindrical shank drill chucks. Primary workpiece materials include alloy steel and aluminum as specified by the manufacturer.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Secure the shank fully in a properly sized drill chuck before operation and confirm the chuck is tightened and the spindle is aligned with the intended hole axis. Always wear appropriate eye protection and follow applicable OSHA and shop safety guidelines when operating drilling equipment. Do not exceed the recommended RPM range for the workpiece material and bit diameter.
