Guhring 9041230200070 Spiral Point Tap M20x1.5 Tin

Product Description

The GUHRING 9041230200070 is a spiral point tap engineered for through-hole threading in demanding machining applications. Built from powdered metal and finished with a titanium nitride (TiN) coating, this tap is designed to cut M20 x 1.5 metric fine threads with a 6H class of fit. It features four flutes and a plug chamfer, producing a clean thread entry and pushing chips forward through the hole. With an overall length of 4.921 inches (125 millimeters) and a shank diameter of 0.652 inches, the tap fits standard machine tool holders used in production and job-shop environments. Licensed machinists and tool-and-die professionals are the primary installers.

This tap is suited for through-hole threading operations in high-tensile steel workpieces. The spiral point geometry drives chips ahead of the cutting edges, making it effective in CNC machining centers, drill presses, and tapping arms where chip evacuation is critical. The plug chamfer allows the tap to begin threading with gradual cutting engagement, reducing the chance of tap breakage in harder materials. The right-hand thread direction is standard for conventional M20 x 1.5 applications. The TiN coating reduces friction and extends tool life in steel applications. This is a single-piece tap from GUHRING Series 4123.

Key Features

• M20 x 1.5 metric fine thread, 6H class of fit with D6/D7 thread limit
• Powdered metal construction for improved wear resistance and toughness
• TiN coating reduces friction and extends tool life in high-tensile steel
• 4-flute spiral point design pushes chips forward, optimized for through-hole threading
• Plug chamfer provides gradual cutting engagement to reduce tap breakage risk
• Right-hand thread direction, no coolant-through — suitable for standard machine setups

Compatibility

Designed for through-hole threading in high-tensile steel. Compatible with standard machine tool holders that accept a 0.652-inch shank diameter. Suitable for use in CNC machining centers, drill presses, and tapping arms running M20 x 1.5 metric fine thread operations.

Installation Notes

This tap is installed and operated by machinists or tooling professionals using standard tapping equipment. Before mounting, ensure the machine spindle and tool holder are powered down and secured. Use the correct tap wrench or CNC tool holder matched to the 0.652-inch shank. Apply appropriate cutting fluid for steel to supplement the TiN coating and prolong tool life. Do not reverse the tap under power without confirming the machine is configured for proper thread reversal.
