Hertel C.E13.0635 Extra Length Cobalt Drill Bit 1/4 in

Product Description

The HERTEL C.E13.0635 is a cobalt extra length drill bit designed for drilling through tough materials including hardened steels, stainless steel, and high-strength alloys. The 1/4 inch diameter bit features a 135-degree split-point tip that reduces walking and requires no center punch on most surfaces. At 8.0 inches overall length with a 5.5-inch flute length, it reaches deeper bores than standard jobber-length bits. The bright, uncoated finish is suited for general-purpose metalworking applications. Machinists, tool-and-die workers, and maintenance technicians use this bit in drill presses and handheld drills where extended reach is required.

This bit is appropriate for general-purpose drilling in metalworking and fabrication environments. The extra length makes it well suited for drilling through structural members, tubing, and deep-set holes that standard-length bits cannot reach. It is sold individually and fits into standard 3-jaw drill chucks accepting 1/4 inch shanks. Common use environments include machine shops, fabrication facilities, and industrial maintenance operations.

Key Features

• 1/4 inch (0.2500 inch) diameter for precise sizing
• 135-degree split-point tip reduces walking and improves bite on curved or hardened surfaces
• Cobalt construction provides heat resistance and extended tool life in hard materials
• 8.0 inch overall length with 5.5 inch flute length for deep-reach drilling
• Bright, uncoated finish for general-purpose metalworking use
• Two-flute design for efficient chip evacuation

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard 3-jaw drill chucks and drill presses accepting a 1/4 inch round shank.

Installation Notes

This bit is installed and operated by machinists and maintenance technicians in accordance with standard metalworking practices. Ensure the drill press or handheld drill is powered off and the chuck is fully secured before beginning work. Use appropriate cutting fluid when drilling hard or stainless alloys to reduce heat buildup and extend bit life. Do not exceed the recommended RPM range for the workpiece material and bit diameter.
