Guhring 9005570100000 Spotting Drill 90 Degree 10mm Hss

Product Description

The GUHRING 9005570100000 is a 90-degree spotting drill designed to accurately locate and initiate hole centers before finish drilling operations. Manufactured from high speed steel with a bright, uncoated finish, this single-ended tool features a 10mm cutting diameter and an overall length of 3.504 inches (89mm). The spiral flute geometry and right-hand cutting direction make it a reliable general-purpose spotting tool for machinists and toolroom technicians working across a range of materials. It is part of GUHRING Series 557 and is sold individually.

This spotting drill is suited for use in CNC machining centers, drill presses, and manual mills where precise hole location is required before drilling, countersinking, or boring. The 90-degree included point angle is the most common standard for spotting applications, ensuring consistent center accuracy and minimal runout on subsequent operations. The straight cylindrical shank accepts standard toolholders and collet chucks commonly found in production and job shop environments.

Designed as a general-purpose spotting drill for use in standard straight-shank toolholders and collet chucks. No specific machine model compatibility was provided by the manufacturer for this part.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully powered down and any CNC program is in a safe stopped state before inserting or removing the tool from the holder. Confirm the straight cylindrical shank is fully seated and the collet or set-screw holder is torqued per the toolholder manufacturer specification. Inspect the cutting edges for chips or wear before each use.
