Hertel C.E09.0595 Extra Length Drill Bit 0.2344 in Hss

Product Description

The HERTEL C.E09.0595 is an extra length high-speed steel drill bit designed for deep-hole drilling applications where standard-length bits cannot reach. It features a 118-degree drill point angle suited for general-purpose drilling in a wide range of common materials. The oxide finish provides a mild layer of surface protection and reduces friction during cutting. With a 10.0000-inch overall length and a 7.5-inch flute length, this bit gives machinists and maintenance professionals the reach needed for through-hole work in thick stock, deep cavities, or hard-to-access part geometry. The two-flute design efficiently evacuates chips along the full flute length.

This bit is appropriate for general-purpose drilling in ferrous and non-ferrous metals, plastics, and wood composites. It fits standard drill chucks and is well suited for use in drill presses, CNC machines, and hand-held power drills where extended reach is required. The 0.2344-inch diameter corresponds to a 15/64-inch nominal size, making it a common choice for clearance holes, pilot holes, and through-hole operations in industrial maintenance, fabrication, and machine shop environments.

Key Features

• Extra length design at 10.0000 inches overall length for deep-hole drilling reach
• 7.5-inch flute length supports chip evacuation throughout the full depth of cut
• 118-degree drill point angle for general-purpose use across a broad range of materials
• High-speed steel construction provides a balance of toughness and wear resistance
• Oxide finish reduces surface friction and offers basic corrosion resistance
• Two-flute configuration maintains cutting efficiency and chip clearance

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard drill chucks accepting a 0.2344-inch shank diameter, suitable for use in drill presses, machining centers, and hand-held power drills.

Installation Notes

Secure the bit firmly in the chuck before operation and verify the shank is fully seated to minimize runout. Use appropriate cutting fluid or lubricant when drilling metals to extend tool life and improve hole finish. Reduce feed pressure as the bit exits the workpiece to prevent breakout damage. Always wear appropriate eye protection and follow applicable shop safety practices when operating drilling equipment.
