Hertel C.E09.0437 Extra Length Drill Bit 0.1719 in Hss

Product Description

The HERTEL C.E09.0437 is an extra length twist drill bit designed for deep-hole drilling applications in metal, wood, and general-purpose materials. Manufactured from high-speed steel with an oxide finish, this bit delivers durability and resistance to heat buildup during extended drilling operations. It features a 118-degree drill point angle suited for a wide range of materials, a 7.5-inch flute length, and a 10-inch overall length that allows techs and tradespeople to reach into tight cavities or deep workpieces that standard-length bits cannot access.

This extra length drill bit is used in general-purpose trade and industrial applications where additional reach is required. Common install scenarios include drilling through thick structural members, deep metal housings, electrical panel enclosures, and mechanical assemblies. It is appropriate for use with hand-held drills, drill presses, and machine tools in HVAC, electrical, plumbing, and general mechanical service environments. The two-flute design provides efficient chip evacuation during deep-hole drilling operations.

Key Features

• Extra length design at 10 inches overall length for deep-hole reach
• 7.5-inch flute length maximizes chip evacuation in deep drilling applications
• 118-degree drill point angle suitable for general-purpose material drilling
• High-speed steel construction for heat resistance and extended tool life
• Oxide finish provides corrosion resistance and reduces friction
• Two-flute geometry for consistent chip removal and cutting efficiency

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard drill chucks accepting a 0.1719-inch diameter bit across hand drills, drill presses, and machine tool applications.

Installation Notes

Installation and use of this drill bit should be performed by qualified tradespeople using appropriate personal protective equipment including safety glasses. Secure the workpiece firmly before drilling and confirm the drill chuck is fully tightened before operation. Reduce feed pressure when the bit begins to break through the far side of the material to avoid grab or breakage. Follow applicable OSHA and site safety guidelines when operating drilling equipment.
