Hertel H-8119C190510 Spotting Drill 90 Degree 3/4 Inch

Product Description

The HERTEL H-8119C190510 is a 90-degree spotting drill manufactured from high speed steel with a bright, uncoated finish. Designed for precision hole location and chamfering prior to full drilling operations, this tool establishes an accurate center point that guides follow-on twist drills and reduces walking at hole entry. It features a 3/4 inch cutting diameter, a 10 inch overall length, and a 1.625 inch spiral flute length. The straight cylindrical shank measures 3/4 inch in diameter. Web thinning reduces thrust and improves chip evacuation at the drill tip. This is a single-ended, right-hand cutting tool suited for general purpose spotting applications in machine shop and production environments.

This spotting drill is intended for use on CNC machining centers, drill presses, and manual mills where accurate hole placement is required before drilling, countersinking, or counterboring operations. The 90-degree included angle is compatible with standard drill point angles and common countersink geometries. Its general purpose performance rating makes it suitable across a range of workpiece materials including mild steel, aluminum, brass, and engineering plastics. Licensed machinists, tool-and-die technicians, and production drill press operators are the typical end users.

Key Features

• 90-degree drill point angle for compatibility with standard twist drill tip geometries
• High speed steel construction provides durability across a range of common workpiece materials
• Bright, uncoated finish suitable for use with cutting fluids in general purpose applications
• Web-thinned tip reduces cutting thrust and improves chip clearance
• Two-flute spiral design for efficient chip evacuation during spotting operations
• Straight cylindrical shank for direct mounting in standard drill chucks and collet holders

Compatibility

Designed as a general purpose spotting drill for use in standard 3/4 inch drill chucks and collet systems on CNC machining centers, knee mills, and drill presses.

Installation Notes

Installation should be performed by a qualified machinist following standard tool-change procedures for the host machine. Ensure the machine spindle is fully stopped and the control is in a safe state before loading or unloading the tool. Mount the straight shank securely in a matching collet or drill chuck and verify runout before beginning a production cycle. Always apply an appropriate cutting fluid for the workpiece material to extend tool life.
