Guhring 9039790060000 Thread Forming Tap M6x1.00 Metric Coarse

Product Description

The GUHRING 9039790060000 is a bottoming thread forming tap designed for M6x1.00 metric coarse threads with a 6HX class of fit. Manufactured from High-Speed Steel-E-CO (cobalt-grade HSS) and coated with Titanium Nitride (TiN), this tap is built for cold-forming internal threads without cutting or producing chips. It operates with a right-hand thread direction and covers a tapping depth of 1.1811 inches (30.00 mm). With an overall length of 2.5 inches and 5 oil grooves for lubricant distribution, it is suited for production and maintenance machinists working with blind hole applications.

This tap is intended for blind hole threading in a range of metallic materials including steel, stainless steel, cast iron, and non-ferrous metals, corresponding to material application codes P, M, K, and N. The bottoming chamfer (1.5-2 thread chamfer) allows threading close to the bottom of a blind hole, making it a practical choice for tight-tolerance fixturing, structural fastener prep, and precision component assembly in both job shop and production environments. It belongs to Guhring Series 3979 and carries a D8/D9 thread limit designation.

Key Features

• Thread forming (chipless) design eliminates chip evacuation concerns in blind holes
• TiN coating increases surface hardness and reduces friction for extended tool life
• Cobalt-grade HSS-E-CO substrate handles elevated cutting temperatures in tough alloys
• Bottoming chamfer (1.5-2P) enables threading to near full depth in blind holes
• 5 oil grooves promote consistent lubrication along the tap body during forming
• 6HX class of fit with D8/D9 thread limit ensures compatibility with standard metric tolerance requirements

Compatibility

Designed for M6x1.00 metric coarse blind hole threading in steel, stainless steel, cast iron, and non-ferrous metals. Suitable for use in CNC machining centers, drill presses, and tapping machines configured for right-hand metric thread forming.

Installation Notes

Thread forming taps require the correct forming tap drill size rather than a standard tap drill — consult a metric forming tap drill chart for M6x1.00 before drilling. Apply a suitable tapping fluid or cutting oil to the oil grooves before use; dry forming will shorten tool life significantly. Secure the workpiece fully before tapping and use a tapping attachment or floating holder where possible to prevent tap breakage. This tool is intended for installation by qualified machinists familiar with thread forming processes and proper spindle speed selection for the workpiece material.
