Guhring 9039660140000 Spiral Point Tap M14 X 2 Cobalt

Product Description

The GUHRING 9039660140000 is a spiral point tap designed for through-hole threading in a wide range of metals. It is manufactured from cobalt high-speed steel and features a MolyGlide finish that reduces friction and extends tool life in demanding applications. The tap cuts a right-hand M14 x 2.00 metric thread to a 6H class of fit with a D5/D6 thread limit. At 3.591 inches overall length and a 0.429-inch shank diameter, it fits standard tap holders used in machining centers and manual tapping operations. This is a 3-flute plug chamfer design suited to production threading where chip ejection ahead of the cut matters.

This tap is used for through-hole threading in both manual and CNC machining environments. The spiral point geometry pushes chips forward through the hole, making it well-suited for production runs and deeper through-holes where chip packing is a concern. It is rated for use in aluminum, gray cast iron, malleable iron, spheroidal iron, non-ferrous metals, stainless steel, and steel, covering most common shop materials. This tool is installed and used by machinists, tool and die makers, and maintenance technicians working with M14 x 2 thread specifications.

Key Features

• Cobalt high-speed steel construction for heat resistance and longer tool life in hard or abrasive materials
• MolyGlide finish reduces friction and built-up edge during cutting
• Spiral point geometry ejects chips forward, preventing packing in through-hole applications
• Plug chamfer provides a gradual lead-in suitable for most standard through-hole threading setups
• 6H class of fit with D5/D6 thread limit for consistent, gauged metric thread production
• Right-hand thread direction, no coolant-through required

Compatibility

Designed for through-hole threading applications requiring an M14 x 2.00 right-hand metric thread. Suitable for use in aluminum, gray cast iron, malleable iron, spheroidal iron, non-ferrous metals, stainless steel, and steel. Part of the GUHRING Series 3966.

Installation Notes

This tap is installed and used by machinists in manual or CNC tapping operations. Secure the tap in a properly sized tap holder or collet before use and ensure the workpiece is firmly fixtured. Always use an appropriate cutting fluid for the material being threaded to protect the tool and improve thread quality. Inspect the tap for wear or chipping before each use and replace when thread quality degrades.
