Hertel C.E10.1270 Extra Length Drill Bit 1/2 in Hss

Product Description

The HERTEL C.E10.1270 is an extra length twist drill bit designed for drilling through materials that require greater reach than a standard-length bit provides. Built from high-speed steel with an oxide finish, this bit measures 12 inches in overall length with a 9-inch flute length and a 0.5-inch diameter. The 118-degree split point angle promotes accurate starting and reduces walking on entry. With two flutes and a general-purpose grade, it suits a wide range of drilling applications in metal, wood, and plastics. Electricians, HVAC technicians, plumbers, and pipefitters rely on extra length bits when working through deep assemblies, framing members, or panels where standard bits cannot reach.

This drill bit is suited for residential and light commercial trade applications where extended reach is required. Common scenarios include drilling through wall framing, electrical panels, ductwork flanges, pipe hangers, and structural members. The 9-inch flute length provides efficient chip evacuation during deep-hole drilling operations. It is sold individually and is appropriate for use in standard drill presses, hand drills, and right-angle drill adapters commonly used in trade work.

Key Features

• 12-inch overall length for deep-reach drilling applications
• 9-inch flute length with two flutes for efficient chip removal
• 118-degree point angle for accurate entry on flat and curved surfaces
• High-speed steel construction for durability across metal, wood, and plastic
• Oxide finish helps reduce friction and resist heat buildup during drilling
• General-purpose grade suitable for a broad range of trade applications

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard 1/2-inch drill chucks on corded drills, cordless drills, and drill presses.

Installation Notes

This bit is installed and used by licensed electricians, plumbers, HVAC technicians, and general contractors. Secure the bit firmly in a properly rated chuck before use and confirm the chuck key is removed before powering the drill. When drilling through metal, use appropriate cutting fluid to extend bit life and reduce heat. Wear eye protection and secure the workpiece to prevent movement during drilling.
