Guhring 9007230100000 Carbide Spotting Drill 10mm 90 Deg

Product Description

The GUHRING 9007230100000 is a solid carbide spotting drill designed to create precise center points and guide holes for follow-on drilling operations. Built to Series 723 specifications, it features a 90-degree drill point angle and a 10mm cutting diameter (0.3937 inches), with an overall length of 89mm (3.504 inches). The bright, uncoated finish leaves the carbide substrate fully exposed, which suits applications where coating compatibility or re-grinding economy matters. With two spiral flutes and a right-hand cutting direction, this tool is installed and operated by machinists and toolroom technicians on CNC machining centers and manual drill presses alike.

This spotting drill is suited for general-purpose metal removal applications where accurate hole location is critical before full drilling, countersinking, or tapping sequences. The 25mm flute length (0.984 inches) accommodates shallow spotting depths typical of production work. The straight-cylindrical shank measures 10mm in diameter (0.3937 inches), making it compatible with standard ER collet chucks, drill chucks, and hydraulic toolholders of the appropriate bore size. It is a single-ended tool, meaning full tool length is available for projection and reach considerations during setup.

Key Features

• 90-degree point angle for accurate spot location and chamfering
• Solid carbide construction for rigidity and wear resistance in demanding materials
• Bright, uncoated finish retains re-grindability and suits a wide range of workpiece materials
• Two spiral flutes with right-hand cutting direction for efficient chip evacuation
• Straight-cylindrical shank fits standard collet and drill chuck toolholders
• Single-ended design — full 89mm OAL available for projection planning

Compatibility

Designed as an OEM-specification spotting drill for use in standard straight-shank toolholding systems accepting a 10mm shank diameter; consult GUHRING Series 723 documentation for confirmed machine and holder compatibility.

Installation Notes

Installation and operation should be performed by qualified machinists or toolroom personnel familiar with cutting tool setup practices. Ensure the machine spindle is fully stopped and the tool is properly secured in a clean, correctly sized collet or chuck before powering the machine. Verify runout with a dial indicator after clamping, as excessive runout will reduce spotting accuracy and tool life. Follow the machine manufacturer and toolholder manufacturer guidelines for drawbar torque and clamping force.
