Guhring 9039000140000 Spiral Point Tap M14x2 Cobalt

Product Description

The GUHRING 9039000140000 is a spiral point tap designed for metric coarse through-hole threading applications. Built from cobalt high-speed steel with a bright finish, this plug-chamfer tap drives chips forward ahead of the cut, making it well suited for threading through-holes in a wide range of materials. The 3-flute geometry and D5/D6 thread limit provide consistent thread form to a 6H class of fit. The tap carries a 0.945-inch thread length and a 0.429-inch shank diameter, covering M14 x 2.00 metric coarse thread production in both production-shop and maintenance environments.

This tap is intended for through-hole threading operations in materials including aluminum, gray cast iron, malleable iron, spheroidal iron, non-ferrous metals, and steel. The plug chamfer (typically 3-5 lead threads) allows the tap to start easily in a drilled hole and perform efficiently in CNC machining centers, drill presses, and tapping arms where controlled feed rates are maintained. It is part of the GUHRING Series 3900 and is sized for M14 x 2.00 metric coarse work.

Key Features

• Cobalt HSS construction for improved heat and wear resistance in ferrous and non-ferrous materials
• Spiral point geometry pushes chips forward, preventing chip packing in through-hole applications
• Plug chamfer provides gradual thread engagement and easy hole entry
• 6H class of fit with D5/D6 thread limit for consistent, inspection-ready metric threads
• Bright (uncoated) finish suitable for use with standard cutting fluids
• Right-hand cut, M14 x 2.00 metric coarse thread standard

Compatibility

Designed for M14 x 2.00 metric coarse through-hole threading in aluminum, gray cast iron, malleable iron, spheroidal iron, non-ferrous metals, and steel. Compatible with standard M14 tap holders and collet-style tapping chucks sized for a 0.429-inch shank diameter.

Installation Notes

Tapping should be performed by a qualified machinist or tooling technician following established shop safety procedures. Ensure the workpiece is securely fixtured and the tap is properly aligned to the drilled hole before engagement to avoid tap breakage or thread damage. Use an appropriate cutting fluid or tapping compound matched to the workpiece material. Coolant-through is not supported by this tap; flood or brush-applied coolant is recommended where heat buildup is a concern.
