Hertel H-8119C095205 Spotting Drill 3/8 in 90 Deg Hss

Product Description

The HERTEL H-8119C095205 is a high-speed steel spotting drill designed to accurately locate and start holes before finish drilling. With a 90-degree point angle and a 0.375-inch cutting diameter, this tool creates a precise conical seat that guides twist drills and keeps them on center without walking. The bright, uncoated finish and web-thinned geometry reduce thrust and improve chip evacuation during initial engagement. At 5 inches overall length with a 1-inch flute length, it is well-suited for CNC machining centers, drill presses, and manual mills where controlled, repeatable hole entry is required. Licensed machinists and tool-and-die professionals are the primary users of this tool.

This spotting drill is appropriate for general-purpose metal cutting in both job shop and production environments. The straight cylindrical shank measures 0.375 inches in diameter, making it compatible with standard drill chucks and collet holders commonly found in machine shops. It is a single-ended tool with a right-hand cutting direction and a two-flute spiral configuration. Typical applications include spot drilling prior to twist drilling, countersinking preparation, and center-finding operations on ferrous and non-ferrous workpieces.

Key Features

Compatibility

Designed as a general-purpose spotting drill for use with standard drill chucks and collet holders accepting a 0.375-inch straight cylindrical shank on CNC machining centers, knee mills, and drill presses.

Installation Notes

Installation and operation should be performed by a qualified machinist. Secure the straight cylindrical shank fully within the chuck or collet and verify runout before engaging the workpiece. Always follow machine manufacturer guidelines for spindle speed and feed rate based on workpiece material. Use appropriate cutting fluid for the material being machined to extend tool life and maintain dimensional accuracy.
