Hertel H-8119A095200 Spotting Drill 3/8 in 90 Deg Hss

Product Description

The HERTEL H-8119A095200 is a single-ended spotting drill designed to create accurate center points and chamfered entry holes before full drilling operations. Built from high-speed steel (HSS) with a bright, uncoated finish, it features a 90-degree point angle and a 3/8-inch cutting diameter with a matching 3/8-inch straight cylindrical shank. The spiral flute geometry is web-thinned to reduce thrust and improve chip clearance. Overall length is 2 inches with a 1-inch flute length, making it a compact tool suited for precision hole-starting on the drill press or CNC machining center. Right-hand cut direction is standard.

This spotting drill is intended for general-purpose spotting and chamfering operations across a range of materials in machine shop, fabrication, and maintenance environments. The 90-degree included angle matches the geometry of most standard jobber and twist drills, helping ensure proper drill seating and hole location accuracy. It is well suited for use on metal, ferrous and non-ferrous, where a clean, accurately located starter hole is required before proceeding to a finish drill or reamer. Machinists, tool-and-die technicians, and maintenance mechanics commonly reach for this tool in both manual and CNC setups.

Key Features

• 90-degree point angle matches standard drill geometry for accurate hole spotting
• 3/8-inch cutting diameter with a matching straight cylindrical shank for direct collet or chuck mounting
• High-speed steel construction for general-purpose use across common ferrous and non-ferrous materials
• Web-thinned design reduces axial thrust and improves chip evacuation
• Spiral flute, right-hand cut for standard spindle direction
• Bright, uncoated finish — suitable for use with cutting fluid or dry cutting on softer materials

Compatibility

Designed as a general-purpose spotting drill for use in standard 3/8-inch collets, ER collet chucks, or three-jaw drill chucks on manual mills, drill presses, and CNC machining centers.

Installation Notes

Install in a collet or drill chuck appropriate for a 3/8-inch straight shank and verify concentricity before operation. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use cutting fluid appropriate to the workpiece material to extend tool life and maintain surface finish. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection.
