Cleveland C70168 Jobber Drill Bit Size 35 Cobalt 135

Product Description

The CLEVELAND C70168 is a jobber-length drill bit designed for precision drilling in metalworking and fabrication applications. Built from M42 cobalt high-speed steel with a gold oxide coating, this bit delivers increased heat and wear resistance compared to standard HSS tooling. It measures 2-5/8 inches overall length with a 1-1/2 inch flute length and a straight-cylindrical shank diameter of 0.1100 inches. The 135-degree split point reduces walking and requires no center punch on most surfaces. This is a wire gauge size 35 bit with a decimal equivalent of 0.1100 inches, suited for production and maintenance drilling environments.

This drill bit is rated for use in aluminum as its primary workpiece material, making it a solid choice for sheet metal shops, HVAC fabrication, electrical panel work, and general maintenance drilling. The spiral flute geometry promotes chip evacuation during through-hole drilling. Right-hand cut orientation is standard for conventional drill press and handheld power tool use. Conforming to NAS 907 Type J standards, it fits applications where specification compliance is required, such as aerospace and defense maintenance work.

Key Features

• M42 cobalt steel construction for elevated heat resistance during high-speed drilling
• 135-degree split point reduces thrust force and prevents bit walking without a center punch
• Gold oxide coating provides additional lubricity and surface hardness
• Web-thinned, tapered web configuration improves chip flow and reduces cutting resistance
• Straight-cylindrical shank fits standard drill chucks without adapters
• Meets NAS 907 Type J specification for use in controlled manufacturing environments

Compatibility

Designed as a wire gauge size 35 jobber-length drill bit suitable for use with standard 3-jaw drill chucks in drill presses, hand drills, and CNC equipment where a 0.1100-inch diameter straight-shank bit is required.

Installation Notes

This bit is installed and removed by a licensed machinist or qualified technician using a standard keyed or keyless drill chuck. Ensure the drilling machine is fully powered off and the chuck is secured before changing bits. Apply appropriate cutting fluid when drilling ferrous or hard alloy materials to extend tool life. Do not exceed the recommended RPM range for the workpiece material and bit diameter.
