Guhring 9005680040000 Spotting Drill 4mm Hss Tin

Product Description

The GUHRING 9005680040000 is a 90-degree spotting drill designed for precision center-starting of hole locations in metal workpieces. Built from high speed steel (HSS) with a titanium nitride (TiN) coating, it delivers improved surface hardness and extended tool life compared to uncoated HSS tooling. The cutting diameter measures 4mm (0.1575 inches), and the overall length is 55mm (2.165 inches). With a 12mm (0.472 inch) spiral flute length and a straight cylindrical shank, this tool is suited for general-purpose spotting operations on CNC machining centers, drill presses, and manual mills. Installation and use are performed by machinists and toolroom professionals.

This spotting drill is intended for general-purpose metal spotting applications in both production shop and toolroom environments. The 90-degree point angle is a common standard for creating accurate starting points before twist drilling, countersinking, or reaming. The single-ended design and straight cylindrical shank allow straightforward clamping in standard drill chucks or collet holders. It is part of GUHRING Series 568 and is sold individually.

Key Features

• 90-degree drill point angle for accurate hole location spotting
• High speed steel construction with TiN coating for increased wear resistance
• 4mm cutting diameter with matching 4mm straight cylindrical shank
• 12mm spiral flute length supports chip evacuation during spotting
• Two-flute, right-hand cut configuration for standard CNC and manual machine tool use
• Single-ended design for direct chuck or collet mounting

Compatibility

Designed as a general-purpose spotting drill for use in standard drill chucks and collet systems accepting a 4mm straight cylindrical shank, suitable for typical CNC machining centers, knee mills, and drill presses used in metal fabrication and toolroom applications.

Installation Notes

This tool is installed and operated by machinists in machine shop environments. Secure the shank fully in a collet or drill chuck before operation and verify runout before cutting. Always set spindle speed and feed rate per material recommendations for HSS tooling before engaging the workpiece. Inspect the cutting edges for wear or chipping before each use and replace the tool if damage is observed.
