Hertel H-8119A222200 Spotting Drill 7/8 in 90 Deg Hss

Product Description

The HERTEL H-8119A222200 is a single-ended spotting drill designed to create accurate center locations before full drilling operations. Made from high-speed steel with a bright, uncoated finish, this tool features a 90-degree point angle and a 0.875-inch cutting diameter. The spiral flute geometry and web-thinned design reduce cutting resistance and help maintain positional accuracy at the start of a hole. With an overall length of 2.5 inches and a straight cylindrical shank, this drill fits standard chucks and collets used in manual and CNC machining environments. Machinists, tool and die makers, and metalworking professionals install this type of tooling in production and job shop settings.

This spotting drill is suited for general-purpose metal removal applications where precise hole location is required before transition to a twist drill, reamer, or boring tool. The 90-degree point angle is a common standard in spotting operations and pairs well with most twist drill point geometries. The 1.25-inch flute length provides adequate chip clearance for shallow spotting depths typical of this tool class. It is designed for right-hand cutting direction and performs in ferrous and non-ferrous materials where high-speed steel tooling is appropriate.

Key Features

• 90-degree drill point angle for accurate hole location and chamfering
• 0.875-inch cutting diameter with matching straight cylindrical shank for secure chuck retention
• High-speed steel construction suitable for general-purpose metalworking
• Bright, uncoated finish for standard cutting applications
• Web-thinned geometry to reduce thrust and improve point engagement
• Two-flute spiral design for efficient chip evacuation during spotting operations

Compatibility

Designed as a general-purpose spotting drill compatible with standard drill presses, milling machines, and CNC machining centers that accept a 0.875-inch straight cylindrical shank.

Installation Notes

Installation and use of this tool should be performed by qualified machinists or metalworking professionals. Ensure the machine spindle is fully stopped and the tool is properly seated and secured in the chuck or collet before initiating a cut. Use appropriate cutting speeds and feeds for the workpiece material and always wear appropriate eye protection. Inspect the cutting edges for wear or chipping before each use.
