Hertel C.E10.0595 Extra Length Drill Bit 0.2344 in Hss

Product Description

The HERTEL C.E10.0595 is an extra length drill bit designed for applications requiring extended reach beyond what standard-length bits provide. Built from high-speed steel with an oxide finish, this bit handles general-purpose drilling in metal, wood, and plastic. It features a 118-degree point angle suited for flat-starting on most common materials and a two-flute design that clears chips efficiently during deep-hole drilling. The 12-inch overall length and 9-inch flute length give machinists and fabricators the clearance needed to drill through thick stock or access recessed bore locations that shorter bits cannot reach.

This bit is appropriate for use in machine shops, fabrication facilities, and maintenance environments where deep-hole drilling is a routine requirement. The 0.2344-inch diameter corresponds closely to a 15/64-inch nominal size, making it a common choice for clearance holes, pilot holes before reaming, and through-hole drilling in structural components. It is intended for use in drill presses, milling machines, and hand-held power drills with adequate chuck capacity. General-purpose grade construction makes it suitable for intermittent production and repair work rather than high-cycle production runs.

Key Features

• High-speed steel construction provides hardness and wear resistance for general-purpose drilling
• Oxide finish reduces friction and offers basic corrosion resistance during storage and use
• 118-degree point angle self-centers on flat surfaces and works across a wide range of materials
• 9-inch flute length supports chip evacuation during deep-hole drilling passes
• 12-inch overall length provides extended reach for deep stock or hard-to-access bore locations
• Two-flute geometry balances cutting speed with chip clearance in standard drilling operations

Compatibility

Designed as a general-purpose extra length drill bit compatible with any drill press, milling machine, or hand-held power drill equipped with a chuck capable of accepting a 0.2344-inch shank diameter.

Installation Notes

This bit is installed and serviced by machinists, fabricators, and maintenance technicians. Secure the shank fully in the chuck and verify concentricity before drilling. Reduce feed rate and use appropriate cutting fluid when drilling ferrous metals to extend tool life and prevent work hardening. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is present.
