Hertel H-8119A190500 Spotting Drill 3/4 in 90 Deg Hss

Product Description

The HERTEL H-8119A190500 is a single-ended spotting drill designed to create precise starter holes and accurately locate drill points before through-hole or deep-hole drilling operations. Built from high-speed steel with a bright, uncoated finish, this tool features a 90-degree point angle and a 0.75-inch cutting diameter. The straight cylindrical shank seats securely in standard drill chucks and collet holders. With a web-thinned construction, the H-8119A190500 reduces axial thrust at the point and promotes clean, accurate hole positioning. Machinists, tool-and-die technicians, and CNC setup operators rely on this style of spotting drill in general-purpose metal-cutting applications.

This spotting drill is suited for use on standard vertical mills, drill presses, and CNC machining centers where accurate hole location is required before full-depth drilling. It performs well in carbon steel, alloy steel, aluminum, and similar machinable materials. The right-hand spiral flute configuration aids chip evacuation during the shallow spotting pass. Its compact 2.25-inch overall length makes it practical for setups with limited tool clearance or shorter spindle noses.

Key Features

• 90-degree point angle for accurate drill-point spotting and countersink starting
• 0.75-inch cutting diameter with matching 0.75-inch straight cylindrical shank
• High-speed steel construction for general-purpose metal-cutting durability
• Bright, uncoated finish compatible with most cutting fluids and coolants
• Web-thinned point reduces thrust and improves centering accuracy
• Two spiral flutes with right-hand cutting direction for standard spindle rotation

Compatibility

Designed as a general-purpose spotting drill compatible with standard 3/4-inch drill chucks, ER collet systems, and straight-shank toolholders used on drill presses, knee mills, and CNC machining centers.

Installation Notes

Installation and use of this tooling should be performed by a qualified machinist or toolroom technician. Secure the shank fully in a properly sized chuck or collet and verify runout before use. Power down the spindle and confirm the machine is in a safe, locked-out state before installing or removing any cutting tool. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life and maintain dimensional accuracy.
