Hertel C.E09.1270 Extra Length Drill Bit 1/2 in 118 Deg Hss

Product Description

The HERTEL C.E09.1270 is a 1/2-inch extra length drill bit designed for through-hole and deep-hole drilling applications in metal, wood, and general-purpose materials. Built from high-speed steel with an oxide finish, it delivers solid wear resistance under standard shop conditions. The 118-degree split-point angle provides a self-centering start that reduces walking on flat stock. With a 10-inch overall length and a 7.5-inch flute length, this bit reaches deeper than a standard jobber drill, making it the right choice when extended reach into a workpiece or fixture is required. A two-flute design promotes efficient chip evacuation during the cut.

This extra length drill bit is suited for machinists, maintenance technicians, fabricators, and tool-and-die tradespeople working in general-purpose production or repair environments. It fits standard drill presses, milling machines, and hand-held drilling equipment that accept a 1/2-inch shank. The extended OAL is particularly useful when drilling through thick stock, deep castings, long spacers, or when a standard-length bit cannot clear the workpiece geometry.

Key Features

• 1/2-inch diameter with a 10-inch overall length for extended-reach drilling
• 118-degree drill point angle for general-purpose entry into a wide range of materials
• High-speed steel construction provides hardness and toughness for production use
• Oxide finish adds a layer of surface protection against corrosion and light heat
• 7.5-inch flute length promotes chip clearance in deep-hole applications
• Two-flute geometry balances cutting speed with chip evacuation efficiency

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard 1/2-inch drill chucks on drill presses, milling machines, and corded hand drills used in machining and fabrication applications.

Installation Notes

Installation and use of this drill bit should be performed by machinists or qualified tradespeople familiar with rotating cutting tools. Secure the shank fully in the chuck and verify runout before beginning a cut. Wear appropriate eye protection and ensure the workpiece is clamped or fixtured to prevent movement. Do not exceed the rated speed range for the material being drilled, and allow adequate chip clearing during deep-hole operations to prevent bit deflection or breakage.
