Guhring 9041230140070 Spiral Point Tap M14 X 1.5

Product Description

The GUHRING 9041230140070 is a spiral point plug tap designed for through-hole threading in metric fine applications. Built from powdered metal and finished with a titanium nitride (TiN) coating, it delivers extended tool life in demanding materials including high-tensile steel. The tap features a 4-flute spiral point geometry that pushes chips forward through the hole, keeping the flutes clear during the cut. It carries a 6H thread tolerance class with a D4/D5 thread limit, suitable for standard metric fine threaded assemblies. Overall length is 3.937 inches with a shank diameter of 0.429 inches. Licensed machinists and tooling professionals install this tap in CNC machining centers, manual mills, and drill presses where M14 x 1.5 through-hole threads are required.

This tap is intended for through-hole threading operations in ferrous materials, particularly high-tensile steel. The M14 x 1.5 metric fine thread profile is common in automotive, heavy equipment, and industrial machinery applications where fine-pitch threads provide greater clamping force and vibration resistance. The plug chamfer style requires a pre-drilled through hole and is well suited for production environments where speed and chip control are priorities. Right-hand thread direction makes it compatible with standard toolholders and tap adapters.

Key Features

• M14 x 1.5 metric fine thread form with plug chamfer for through-hole threading
• Powdered metal construction for improved wear resistance over standard HSS
• TiN coating reduces friction and extends tool life in high-tensile steel
• 4-flute spiral point geometry pushes chips forward, reducing clogging in through-hole applications
• 6H class of fit with D4/D5 thread limit for standard metric fine tolerance requirements
• Right-hand thread direction, compatible with standard tap holders and floating adapters

Compatibility

Designed for through-hole threading in high-tensile steel and similar ferrous materials. Part of GUHRING Series 4123. Coolant-through capability is not available on this tap; external or flood coolant is recommended for high-cycle production use.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for M14 x 1.5 before threading. Use appropriate cutting fluid or flood coolant to extend tool life and maintain thread quality. Do not reverse a spiral point tap mid-thread in a blind hole; this tap is designed for through-hole applications only.
