Guhring 9057360020000 Spiral Point Tap M2 X 0.4

Product Description

The GUHRING 9057360020000 is a spiral point plug tap designed for through-hole threading in metric fine applications. Built from powdered metal with a titanium nitride (TiN) finish, it delivers extended wear resistance and reduced friction during tapping operations. The M2 x 0.4 thread form, 3-flute geometry, and plug chamfer make it well suited for machine tapping in production environments. With an overall length of 1.7717 inches and a thread length of 0.315 inches, this tap fits standard tap holders used by machinists and tool-and-die professionals. The 6H class of fit and D3 thread limit ensure consistent, tolerance-controlled threads on every pass.

This tap is engineered for through-hole threading across a wide range of workpiece materials. The TiN coating provides thermal and abrasion resistance, making it effective in both ferrous and non-ferrous applications. It belongs to GUHRING Series 5736 and is sized for small-diameter precision work common in instrument, aerospace, and general metalworking trades. Right-hand thread direction is standard for the vast majority of machine tapping setups.

Key Features

• M2 x 0.4 metric fine thread form with 6H class of fit and D3 thread limit for tight tolerance control
• Powdered metal construction provides increased hardness and wear resistance over standard HSS
• TiN coating reduces friction and heat buildup, extending tool life in production runs
• 3-flute spiral point geometry pushes chips forward, keeping the flutes clear during through-hole tapping
• Plug chamfer allows for easy thread starting in through-hole applications
• Right-hand thread direction; no coolant-through feature required for standard tapping operations

Compatibility

Suitable for through-hole threading in aluminum, aluminum alloys, case hardened steel, cast iron, free cutting steel, heat treatable steel, stainless steel, structural steel, sulfured steel, and tool steel.

Installation Notes

This tap is intended for use by machinists and tool-and-die technicians operating drill presses, CNC machining centers, or tapping machines. Always ensure the workpiece is properly secured and the spindle is aligned before beginning the tapping cycle. Use an appropriate tapping fluid or cutting oil for the workpiece material to protect tool life and thread quality. Do not reverse the tap under power without confirming the machine is set for reverse-out extraction.
