Guhring 9039600050000 Spiral Point Tap M5 X 0.8 Cobalt

Product Description

The GUHRING 9039600050000 is a cobalt spiral point tap designed for through-hole threading in metric applications. Built to M5 x 0.8 thread specification with a 6H class of fit and D3/D4 thread limit, this tap produces accurate internal threads in a single pass through the workpiece. The plug chamfer eases entry and distributes cutting load across the leading threads. A MolyGlide finish reduces friction and heat buildup during cutting, extending tool life in production and job-shop environments. Three flutes push chips forward ahead of the tap, making it well suited for through-hole operations where chip evacuation is straightforward.

This tap is intended for through-hole threading in a wide range of materials including aluminum, gray cast iron, malleable iron, spheroidal iron, non-ferrous metals, and steel. The cobalt construction provides added heat resistance compared to standard high-speed steel, making it a practical choice when cutting tougher alloys or running at elevated speeds. It fits standard tap holders used by machinists, maintenance technicians, and toolroom professionals working with M5 threaded fastener applications.

Key Features

• M5 x 0.8 metric thread with 6H class of fit for precise tolerance control
• Cobalt construction for improved heat resistance and wear life over standard HSS
• MolyGlide finish reduces cutting friction and extends tool life
• Plug chamfer distributes entry load across multiple leading threads
• 3-flute spiral point design pushes chips forward for clean through-hole threading
• Right-hand thread direction; no coolant-through requirement

Compatibility

Designed for through-hole threading of M5 x 0.8 metric threads in aluminum, gray cast iron, malleable iron, spheroidal iron, non-ferrous metals, and steel. Part of the GUHRING Series 3960.

Installation Notes

Installation and use of this tap should be performed by a qualified machinist or toolroom technician familiar with tapping operations. Power down and de-energize any machine tool before changing tooling. Secure the tap in a properly sized tap holder or collet chuck to prevent runout. Use an appropriate cutting fluid for the workpiece material to maximize tool life and thread quality.
