Guhring 9039060180000 Spiral Point Tap M18 X 2.5

Product Description

The GUHRING 9039060180000 is a spiral point tap designed for right-hand, through-hole threading in demanding metalworking applications. Built from powdered metal and finished with a titanium nitride (TiN) coating, this tap delivers the wear resistance and edge retention required when threading aerospace alloys and stainless steel. It cuts an M18 x 2.5 Metric Coarse thread to a 6H class of fit with a D6/D7 thread limit. The plug chamfer provides a gradual cutting action suited to through-hole work. Four flutes evacuate chips forward ahead of the tap, keeping the thread form clean and reducing the risk of re-cutting.

This tap is intended for through-hole threading operations in materials that demand high tool performance, specifically aerospace alloys and stainless steel. It is suited to CNC machining centers and manual tapping setups where consistent 6H thread tolerances are required. The TiN coating reduces friction and extends tool life in production environments where cycle counts are high. Machinists and tool-and-die professionals working to aerospace or precision manufacturing specifications will find this tap appropriate for those tolerance classes.

Key Features

• M18 x 2.5 Metric Coarse thread form, 6H class of fit
• Powdered metal construction for improved hardness and wear resistance over standard HSS
• TiN coating reduces friction and extends tool life in abrasive materials
• 4-flute spiral point design pushes chips forward for clean through-hole threading
• Plug chamfer for gradual thread engagement in through-hole applications
• D6/D7 thread limit for controlled oversize tolerance range

Compatibility

Rated for threading aerospace alloys and stainless steel. Designed for through-hole applications where an M18 x 2.5 Metric Coarse, 6H thread is specified. No coolant-through capability; suitable for external coolant or cutting fluid application.

Installation Notes

Installation should be performed by a qualified machinist following standard tapping procedures. Ensure the workpiece is securely fixtured and the spindle is properly aligned before engaging the tap to prevent thread lead errors or tool breakage. Apply appropriate cutting fluid for the material being threaded, particularly when working stainless steel or aerospace alloys. Do not reverse the tap under power without confirming the machine is set for proper reversing cycle.
