Guhring 9007230080000 Spotting Drill 8mm Solid Carbide

Product Description

The GUHRING 9007230080000 is a solid carbide spotting drill designed to create accurate center-point indentations that guide twist drills, step drills, and other rotating tools into precise starting positions. Built to Series 723 specifications, this single-ended tool features a 90-degree drill point angle, an 8 mm (0.3150 inch) cutting diameter, and a 79 mm (3.1102 inch) overall length. The bright, uncoated finish preserves the carbide substrate at its native hardness, making it suitable for a wide range of workpiece materials where coating interaction is a concern. A spiral flute geometry and right-hand cutting direction ensure clean chip evacuation and consistent entry geometry on each operation.

This spotting drill is intended for general-purpose spotting and center-marking applications in machining environments. The 21 mm (0.8268 inch) flute length accommodates typical spotting depths without excessive engagement, and the straight-cylindrical 8 mm shank seats cleanly in standard drill chucks, collet chucks, and toolholders of matching bore size. It suits CNC machining centers, drill presses, and manual mills where repeatable hole location is required before full-depth drilling operations.

Key Features

• 90-degree drill point angle for accurate spot indentations that match common twist drill included angles
• Solid carbide construction for rigidity and wear resistance across general-purpose materials
• Bright, uncoated finish retains full carbide hardness without coating build-up concerns
• Spiral flute geometry with right-hand cut for efficient chip evacuation during spotting
• Straight-cylindrical shank compatible with standard chucks and collet systems
• Single-ended design for straightforward tool setup and replacement

Compatibility

Designed as a general-purpose spotting drill for use in standard drill chucks and collet holders accepting an 8 mm straight-cylindrical shank.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with rotating cutting tools. Ensure the machine spindle is fully stopped and locked out before loading or removing the tool from the holder. Confirm the chuck or collet bore matches the 8 mm shank diameter and that the tool is seated and tightened to the toolholder manufacturer's recommended procedure before beginning any cut. Do not exceed the spindle speed and feed rate parameters established for the workpiece material and machine rigidity.
