Hertel C.E12.2223 Extra Length Drill Bit 7/8 in Hss

Product Description

The HERTEL C.E12.2223 is an extra length twist drill bit designed for deep-hole drilling applications where standard-length bits cannot reach. Built from high-speed steel (HSS) with an oxide finish, this bit measures 7/8 inch (0.875 inches) in diameter and delivers a 118-degree point angle suited for general-purpose drilling in metal, wood, and plastics. The 18-inch flute length and 24-inch overall length give technicians and tradespeople the reach needed for through-drilling in thick structural members, deep fixtures, or hard-to-access assemblies. Two flutes provide efficient chip evacuation during extended cuts.

This extra length drill bit is suited for maintenance, fabrication, and installation work across mechanical, HVAC, plumbing, and electrical trades. It performs in situations where a standard jobber-length bit falls short - drilling through deep wall assemblies, structural steel, or stacked material. The general-purpose grade makes it a versatile shop and field tool for professionals who need consistent performance without specialty tooling.

Key Features

• 7/8 inch diameter with 0.8750 inch decimal equivalent for precise fit selection
• 24-inch overall length provides extended reach for deep or obstructed drilling locations
• 18-inch flute length supports chip clearance throughout deep passes
• 118-degree split point angle for general-purpose drilling in metal, wood, and plastics
• High-speed steel construction handles moderate heat and wear in continuous use
• Oxide finish provides light corrosion resistance and reduced friction at the cutting edge

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard drill chucks and drill presses that accept 7/8 inch shank tooling.

Installation Notes

This bit is installed and operated by machinists, maintenance technicians, and trade professionals using standard drill presses, magnetic drills, or heavy-duty corded drills with appropriate chuck capacity. Secure the workpiece firmly before drilling and use cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup. Inspect the cutting edges before each use - a dull or chipped tip on an extra length bit increases deflection risk during deep passes. Follow applicable shop safety standards and wear appropriate eye protection at all times.
