Hertel H-8119A254000 Spotting Drill 1 in Hss 90 Deg

Product Description

The HERTEL H-8119A254000 is a 1-inch diameter spotting drill designed to create accurate starter holes that guide twist drills and reduce walking on workpiece surfaces. Built from high-speed steel with a bright, uncoated finish, this tool delivers reliable performance across general-purpose drilling applications. The 90-degree point angle is the standard choice for most spotting operations, allowing subsequent drill points to seat cleanly without deflection. The tool features a spiral flute design with two flutes and a web-thinned construction that reduces thrust during entry. Overall length is 2.5 inches with a 1-inch straight cylindrical shank for direct chuck or collet mounting.

This spotting drill is suited for use in machine shops, maintenance environments, and production settings where hole location accuracy is critical before full-depth drilling. The straight cylindrical shank accommodates standard drill chucks and toolholders. The general-purpose tool performance rating makes it appropriate for a range of common ferrous and non-ferrous workpiece materials. Right-hand cutting direction is standard for conventional spindle rotation. Single-ended construction means the full tool length is dedicated to one cutting end.

Key Features

• 1-inch cutting diameter with matching 1-inch straight cylindrical shank for secure tool holding
• 90-degree drill point angle for standard spotting and countersink-start operations
• High-speed steel construction provides toughness and regrindability for general-purpose use
• Web-thinned design reduces cutting thrust and improves chip clearance at entry
• Spiral flute geometry with 2 flutes and 1.25-inch flute length for efficient chip evacuation
• Bright uncoated finish suitable for use with cutting fluids across a variety of materials

Compatibility

Designed as a general-purpose spotting drill compatible with standard drill presses, CNC machining centers, and manual mills equipped with toolholders or drill chucks accepting a 1-inch straight cylindrical shank.

Installation Notes

Installation is performed by machining professionals familiar with rotating cutting tools. Ensure the spindle is fully stopped and the machine is locked out before inserting or removing the tool from the chuck or collet. Verify shank seating and runout before beginning a cut. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality.
