Guhring 9005570030000 Spotting Drill 90 Degree 3mm Hss

Product Description

The GUHRING 9005570030000 is a 90-degree spotting drill designed to create accurate center points for subsequent drilling operations. Machined from high speed steel (HSS) with a bright, uncoated finish, it delivers reliable performance in general-purpose applications. The cutting diameter is 3mm (0.1181 inches) with a matching 3mm straight-cylindrical shank, and the overall length is 46mm (1.811 inches). With a 12mm (0.4724 inch) spiral flute length and a two-flute, right-hand cut geometry, this tool provides clean entry points and consistent angular contact across a wide range of workpiece materials. It belongs to GUHRING Series 557 and is sold as a single-ended tool.

This spotting drill is suited for general-purpose machining environments including job shops, production floors, and maintenance operations. It is used ahead of twist drills, gun drills, or other hole-making tools to establish a precise starting location, reduce drill walk, and improve hole position accuracy. The 90-degree point angle is a common standard that matches the included angle of many twist drills, making it versatile across CNC machining centers and manual knee mills alike. It is intended for use by machinists and toolroom professionals working in metal fabrication and precision machining.

Installation Notes

Installation and use should be performed by qualified machinists following applicable shop safety procedures. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool from the holder. Secure the shank fully in the chuck or collet to the recommended grip length before operation. Do not use this tool for full-depth drilling beyond its rated spotting application.
