Hertel C.E09.0873 Extra Length Drill Bit 0.3438 in Hss

Product Description

The HERTEL C.E09.0873 is an extra length high-speed steel drill bit designed for drilling operations that require greater reach than standard-length tooling provides. Built from high-speed steel with an oxide finish, this bit delivers reliable performance in general-purpose drilling applications across a range of workpiece materials. At 10 inches overall length with a 7.5-inch flute length, it gives machinists and fabricators the clearance needed to drill deep holes or access recessed features without a drill extension. The 118-degree drill point angle is the standard geometry for general-purpose work in steel, aluminum, and similar materials.

This bit is suited for use in machine shops, maintenance and repair environments, and fabrication operations where extended reach is required. It fits standard drill chucks and can be run in drill presses, lathes, or hand-held power drills when the application allows. The 0.3438-inch diameter corresponds to the 11/32-inch fractional size, a common call-out in structural and mechanical drilling work. General-purpose grade construction makes it appropriate for production and one-off jobs alike.

Key Features

• Extra length design at 10 inches overall length for deep-hole and extended-reach applications
• High-speed steel construction for durability across general-purpose drilling tasks
• Oxide finish provides basic surface protection and reduces friction during cutting
• 118-degree drill point angle suits a wide range of common workpiece materials
• 7.5-inch flute length promotes chip evacuation in deep drilling operations
• Two-flute geometry standard for twist drill bits in general machining use

Compatibility

Designed as a general-purpose extra length twist drill bit compatible with standard drill chucks accepting a 0.3438-inch shank in drill presses, CNC drilling machines, lathes, and hand-held power drills.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tradespeople familiar with rotating cutting tool safety. Secure the bit firmly in the chuck and verify there is no runout before beginning a cut. Always wear appropriate eye protection and ensure the workpiece is properly clamped or fixtured. Follow applicable shop safety standards and equipment manufacturer guidelines for spindle speed and feed rate selection.
