Guhring 9039030140000 Spiral Flute Tap M14 X 2.00 Cobalt

Product Description

The GUHRING 9039030140000 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 handles M14 x 2.00 thread sizes with a modified bottoming chamfer for threading close to the bottom of blind holes. The 40-degree helix angle and fast flute style promote efficient chip evacuation during the cut. This tap is intended for use by machinists and tool-and-die professionals who require tight tolerance threading in production or job-shop environments. It carries a 6H class of fit and a D5-D6 thread limit, making it suitable for standard metric thread assemblies.

This tap is suited for threading blind holes in a range of materials including aluminum and other non-ferrous metals, gray cast iron, malleable iron, spheroidal iron, and steel. Its cobalt construction provides added heat resistance compared to standard HSS taps, making it a practical choice when cutting harder ferrous materials or in applications where tool life is a priority. It is a right-hand flute, right-hand thread design and belongs to the GUHRING Series 3903.

Key Features

• Modified bottoming chamfer for threading close to the bottom of blind holes
• 40-degree helix angle with fast flute style for efficient chip evacuation
• Cobalt construction for increased heat resistance and tool life in ferrous and non-ferrous materials
• 6H class of fit with D5-D6 thread limit for standard metric tolerance requirements
• Right-hand flute and right-hand thread orientation
• No coolant-through design — suitable for conventional coolant application methods

Compatibility

Designed for blind hole threading in M14 x 2.00 metric coarse applications across aluminum and other non-ferrous metals, gray cast iron, malleable iron, spheroidal iron, and steel. Compatible with standard tap holders accepting a 0.4290-inch shank diameter with a 0.3220-inch square drive.

Installation Notes

Installation is performed by machinists using standard tapping equipment or CNC machining centers with appropriate tap holders. Power down and de-energize all equipment before changing tooling. Ensure correct starting torque and feed rate for the workpiece material to avoid tap breakage. Always verify hole depth and diameter prior to tapping to achieve the specified 6H thread tolerance.
