Hertel C.E10.0357 Extra Length Drill Bit 0.1406 in Hss

Product Description

The HERTEL C.E10.0357 is an extra length high-speed steel drill bit designed for deep-hole drilling applications where standard length bits cannot reach. It features a 0.1406-inch diameter cutting edge, a 118-degree drill point angle, and an oxide finish that reduces friction and helps resist corrosion during use. With a 9-inch flute length and 12-inch overall length, this bit provides extended reach in metal, wood, and plastic substrates. A two-flute geometry promotes chip evacuation in deep bore applications. This bit is used by machinists, maintenance technicians, pipefitters, and mechanical contractors working on tight-clearance or deep-reach drilling tasks.

The C.E10.0357 is suited for general-purpose drilling in production and maintenance environments. Its extra length makes it appropriate for applications such as drilling through structural members, crossing wall cavities, or reaching recessed points in mechanical assemblies. It is commonly used in HVAC, plumbing, and electrical rough-in work where standard bits lack the reach to complete the bore in a single pass.

Key Features

• 0.1406-inch diameter for precise bore sizing in extended-reach applications
• 118-degree drill point angle provides a general-purpose cutting profile suitable for most common materials
• 9-inch flute length supports chip clearance throughout the full depth of cut
• 12-inch overall length provides extra reach beyond standard jobber-length bits
• Oxide finish reduces friction and provides light corrosion resistance
• Two-flute geometry for efficient chip evacuation in deep holes

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard drill chucks and drill presses that accept round-shank bits in the 0.1406-inch diameter range.

Installation Notes

This bit is installed and operated by machinists, pipefitters, electricians, and mechanical contractors using standard drill presses, hand drills, or right-angle drills. Secure the shank fully in the chuck before operation and confirm the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid when drilling metals to extend bit life and improve bore quality. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
