Hertel C.E10.0714 Extra Length Drill Bit 0.2812 in Hss

Product Description

The HERTEL C.E10.0714 is an extra length twist drill bit designed for drilling operations that require extended reach beyond what a jobber-length bit can provide. Machined from high-speed steel with an oxide finish, this bit measures 0.2812 inches in diameter with a 118-degree split point angle, a 9-inch flute length, and a 12-inch overall length. The oxide finish reduces friction and provides moderate corrosion resistance during use. With two flutes and a general-purpose grade rating, it handles a wide range of materials including mild steel, aluminum, wood, and plastics. Machinists, pipefitters, ironworkers, and maintenance technicians rely on this type of bit when working in deep cavities or through thick structural members.

Extra length drill bits like the C.E10.0714 are used in industrial, commercial, and trade applications where standard-length bits cannot reach the required depth. Typical scenarios include drilling through heavy-gauge structural steel, deep cross-members, pipe flanges, and equipment frames. The 12-inch overall length makes it well suited for through-drilling applications in confined or obstructed work areas. Plumbers, pipefitters, and electricians also use bits in this length range when running conduit or pipe through deep framing members or equipment enclosures.

Key Features

• 0.2812 inch diameter for precision sizing in standard drill chucks
• 12-inch overall length provides extended reach for deep-hole drilling
• 9-inch flute length allows chip evacuation in deep passes
• 118-degree point angle suits general-purpose drilling across multiple materials
• High-speed steel construction maintains hardness at elevated cutting temperatures
• Oxide finish reduces friction and provides surface protection during use

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard 3-jaw drill chucks and drill presses that accept round-shank bits in the 0.2812 inch diameter range.

Installation Notes

This bit should be installed in a properly sized drill chuck and secured firmly before operation. Always ensure the workpiece is clamped or fixtured securely to prevent movement during drilling. Use appropriate cutting fluid when drilling ferrous metals to reduce heat buildup and extend bit life. Inspect the cutting edges for wear or chipping before each use and replace the bit if damage is observed.
