Hertel C.E09.0714 Extra Length Drill Bit 0.2812 in Hss

Product Description

The HERTEL C.E09.0714 is an extra length twist drill bit designed for drilling operations that require greater reach than a standard-length bit provides. Built from high-speed steel with an oxide finish, it delivers reliable performance in general-purpose drilling applications across a range of ferrous and non-ferrous materials. The bit measures 10 inches in overall length with a 7.5-inch flute length, making it well suited for deep-hole work where standard jobber bits fall short. The 118-degree split point geometry provides consistent starts and clean entry. At 0.2812 inches (9/32 inch) in diameter, it fits common drill chucks used in handheld and bench-mounted equipment. Machinists, fabricators, maintenance technicians, and HVAC or plumbing trades working with structural materials will find this bit a practical addition to the kit.

This drill bit is intended for general-purpose use in production, maintenance, and repair environments. The extra length is particularly useful when drilling through thick stock, multiple layers, box sections, or in confined spaces where a standard bit cannot reach the workpiece. The two-flute design provides efficient chip evacuation in both through-hole and blind-hole applications. The oxide finish offers a basic level of lubricity and surface protection under normal drilling conditions.

Key Features

• Extra length 10-inch OAL for deep-reach drilling applications
• 7.5-inch flute length for extended chip clearance
• 118-degree drill point angle for general-purpose material entry
• High-speed steel construction for durability across common workpiece materials
• Oxide finish provides surface lubricity and basic corrosion resistance
• Two-flute design promotes efficient chip evacuation

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard drill chucks accepting a 0.2812-inch shank, suitable for handheld drills, drill presses, and milling machine setups used in maintenance and fabrication work.

Installation Notes

Secure the bit firmly in a keyed or keyless chuck rated for the intended RPM before operation. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Use appropriate cutting fluid or lubrication when drilling ferrous materials to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and retire the bit if chipping or excessive wear is observed.
