Guhring 9039180140000 Spiral Flute Tap M14 X 2.00 Cobalt

Product Description

The GUHRING 9039180140000 is a spiral flute tap designed for blind hole threading in metric coarse applications. Built from cobalt high-speed steel with a bright, uncoated finish, it delivers the heat resistance and edge retention needed for tapping alloyed and unalloyed steel. The tap features a modified bottoming chamfer, a 40-degree helix angle, and a fast flute style that efficiently evacuates chips upward out of the hole. With a 6H class of fit and D5/D6 thread limit, it produces threads within tight tolerance ranges required for precision assemblies. Machinists and tool-and-die professionals reach for this tap when consistency and dimensional accuracy in M14 x 2.00 blind holes are critical.

This tap is suited for production and job-shop environments where metric coarse threads are tapped into alloyed steel and unalloyed steel workpieces. The modified bottoming chamfer allows threading closer to the bottom of a blind hole than a standard plug tap, making it useful in tight-clearance applications. The right-hand flute and right-hand thread orientation are standard for conventional CNC and manual tapping operations. It belongs to the GUHRING Series 3918, a line built for reliable performance in ferrous metal threading.

Key Features

• M14 x 2.00 metric coarse thread, 6H class of fit with D5/D6 thread limit
• Modified bottoming chamfer for threading near the bottom of blind holes
• Cobalt construction for improved heat resistance when tapping steel alloys
• 40-degree helix angle with fast flute style for effective chip evacuation
• Right-hand flute and right-hand thread direction — compatible with standard tapping heads and CNC programs
• Bright/uncoated finish — no coating variables to account for in tool offset or coolant setup

Compatibility

Designed for blind hole threading in alloyed steel and unalloyed steel. Fits standard tap holders and tapping heads accepting a 0.429-inch shank diameter with a 0.322-inch square drive. Series 3918 from GUHRING.

Installation Notes

This tap should be installed by a qualified machinist following standard tapping procedures. Before use, verify the pre-drilled hole diameter matches the recommended tap drill size for M14 x 2.00 metric coarse thread. Use appropriate tapping fluid or cutting oil for the workpiece material to extend tool life and maintain thread quality. Inspect the tap and holder for runout before beginning a production run to avoid oversized or off-tolerance threads.
