Hertel C.E09.1032 Extra Length Drill Bit 0.4062 in Hss

Product Description

The HERTEL C.E09.1032 is an extra length high-speed steel drill bit engineered for drilling applications that require greater reach than a jobber-length bit provides. Ground to a 118-degree point angle, this bit suits general-purpose drilling through steel, cast iron, aluminum, wood, and similar materials. The 0.4062-inch diameter corresponds to a standard fractional size, and the 10-inch overall length gives technicians and machinists the clearance needed in deep-bore or extended-reach setups. The oxide finish provides a mild surface treatment that aids in reducing friction and initial wear during use. Two flutes provide efficient chip evacuation during the cut.

This bit is suited for use in machine shops, maintenance and repair operations, fabrication environments, and trade applications where standard-length bits cannot reach the work. Typical installations include drilling through structural members, frames, enclosures, or any application requiring a bit with a 7.5-inch flute length and extended overall reach. It fits into standard drill chucks and can be run in drill presses, CNC machines, or hand-held power drills with a compatible chuck capacity.

Key Features

• 0.4062-inch diameter for precise fractional-size hole production
• 10-inch overall length for extended-reach drilling applications
• 7.5-inch flute length maximizes chip clearance in deep holes
• 118-degree point angle optimized for general-purpose use on a wide range of materials
• High-speed steel construction provides hardness and heat resistance during cutting
• Oxide finish reduces surface friction and initial wear

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard drill chucks capable of accepting a 0.4062-inch shank diameter.

Installation Notes

Install in a properly rated drill press, CNC spindle, or hand-held power drill with a chuck rated for the shank diameter. Ensure the bit is fully seated and the chuck is tightened before operation. Use appropriate cutting fluid when drilling ferrous metals to extend tool life and maintain hole quality. Always wear appropriate eye protection and secure the workpiece before beginning the cut.
