Hertel C.E10.1588 Extra Length Drill Bit 5/8 in Hss

Product Description

The HERTEL C.E10.1588 is an extra length twist drill bit designed for deep-hole drilling applications where a standard-length bit cannot reach. Built from high-speed steel with an oxide finish, it delivers reliable cutting performance in a range of metals and general-purpose materials. The bit measures 5/8 inch in diameter with a 12-inch overall length and a 9-inch flute length, giving tradespeople and machinists the extended reach needed for fabrication, maintenance, and repair work. The 118-degree split or conventional point geometry is a standard configuration suited to a wide variety of workpiece materials.

This bit is suited for use in industrial and commercial applications where extended drilling depth is required, such as drilling through structural steel, pipe, heavy plate, or deep cross-members. It is commonly used by millwrights, pipefitters, ironworkers, and maintenance machinists. The 2-flute design efficiently clears chips from deep bores, reducing heat buildup and maintaining hole accuracy at extended depths. General-purpose grade makes it a practical choice for production shops and field service alike.

Key Features

• Extra length design with 12-inch overall length for deep-hole drilling access
• 9-inch flute length maximizes chip evacuation in deep bores
• 5/8-inch diameter with 0.6250-inch decimal equivalent for precise fitment
• 118-degree drill point angle suits general-purpose metal drilling
• High-speed steel construction provides hardness and wear resistance
• Oxide finish helps reduce friction and surface galling during cutting

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard drill chucks and drill presses accepting 5/8-inch shank tooling.

Installation Notes

Installation and use should be performed by qualified machinists or tradespeople familiar with drill press or handheld drilling equipment. Secure the workpiece firmly before drilling and ensure the chuck is properly tightened to the shank. Use appropriate cutting fluid for metal applications to extend tool life and improve hole finish. Follow applicable shop safety standards and wear appropriate eye protection during operation.
