Guhring 9039420030000 Thread Forming Tap M3x0.50 Metric

Product Description

The GUHRING 9039420030000 is a thread forming tap designed for M3x0.50 metric threading applications. This right-hand tap is manufactured from High-Speed Steel-E-CO (cobalt-grade HSS) and finished with a TiCN coating to extend tool life in demanding materials. With an overall length of 1.941 inches and a modified bottoming chamfer of 2 to 3 chamfered threads, it is suited for both blind hole and through-hole threading in tight-tolerance work. The 6HX class of fit with thread limits D6 and D7 meets standard metric threading requirements. Installed by machinists and tool-and-die professionals, this tap is part of GUHRING Series 3942.

This tap is intended for use in steel, stainless steel, cast iron, and non-ferrous metals, corresponding to material application codes P, M, K, and N. The modified bottoming chamfer allows threading close to the bottom of blind holes while still providing controlled chip-free thread forming. Its 3xD flute-by-diameter ratio and four oil grooves support consistent lubrication during the forming process. Typical applications include precision component manufacturing, toolroom work, and production threading in ferrous and non-ferrous workpieces.

Key Features

• M3x0.50 metric thread size with 6HX class of fit, thread limits D6 and D7
• Modified bottoming chamfer with 2 to 3 chamfered threads for near-bottom blind hole threading
• High-Speed Steel-E-CO (cobalt-grade) construction for heat and wear resistance
• TiCN coating reduces friction and extends tool life in steel and stainless steel
• Four oil grooves support lubrication throughout the threading operation
• Suitable for blind hole and through-hole threading applications

Compatibility

Compatible with steel, stainless steel, cast iron, and non-ferrous metals. Designed as an OEM-style thread forming tap for metric M3x0.50 threading operations in standard production and toolroom environments.

Installation Notes

Thread forming taps are installed and operated by machinists using a tapping machine, CNC machining center, or hand tapping setup. Always ensure the workpiece and spindle are properly aligned before engaging the tap to prevent cross-threading or breakage. Use appropriate tapping fluid or cutting oil for the workpiece material to reduce friction and heat buildup. This tap does not produce chips, but the correct pilot hole diameter for the thread forming process must be verified against M3x0.50 forming tap specifications before use.
