Guhring 9008770020000 Spiral Point Tap M2x0.4 Metric

Product Description

The GUHRING 9008770020000 is a spiral point tap designed for right-hand through-hole threading in M2 x 0.4 metric thread sizes. Built from powdered metal with a bright finish, it delivers consistent cutting performance in demanding production environments. The plug chamfer configuration allows it to start threading smoothly in through-hole applications. With a 6H thread class of fit and D2/D3 thread limit, this tap produces accurate metric threads that meet standard tolerance requirements. It is part of the GUHRING Series 877 and is well suited for use by machinists, tool and die makers, and maintenance technicians working with small-diameter metric fastener holes.

This tap is appropriate for through-hole threading operations in a range of materials including aluminum, non-ferrous metals, stainless steel, and steel. Its three-flute spiral point geometry pushes chips forward ahead of the cut, making it effective in production drilling and tapping operations on CNC machining centers and manual drill presses where through-holes are accessible. The small M2 thread size makes it common in precision assemblies, electronics enclosures, and light mechanical components.

Key Features

• M2 x 0.4 metric thread size with 6H class of fit and D2/D3 thread limit for standard tolerance threading
• Spiral point geometry pushes chips forward, suited for through-hole applications
• Three flutes for balanced cutting action in small-diameter holes
• Plug chamfer for smooth thread entry in through-hole configurations
• Powdered metal construction for enhanced wear resistance versus standard HSS
• Bright finish with no coating — compatible with a range of cutting fluids
• Right-hand thread direction; no coolant-through feature

Compatibility

Designed for through-hole threading of M2 x 0.4 metric threads in aluminum, non-ferrous metals, stainless steel, and steel workpieces. No specific machine or holder compatibility was provided in the product data.

Installation Notes

This tap should be installed in a tap holder or tapping chuck rated for small-diameter tooling and set to the correct spindle speed for the workpiece material and tap diameter. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter before threading. Apply appropriate cutting fluid for the material being tapped, particularly when working with stainless steel or steel. Avoid excessive feed force on small-diameter taps, as M2 taps are susceptible to breakage if misaligned or overloaded.
