Guhring 9041220160000 Spiral Point Tap M16x2 Metric Coarse

Product Description

The GUHRING 9041220160000 is a spiral point tap designed for through-hole threading in metric coarse applications. Built from powdered metal and finished with a TiN (titanium nitride) coating, this tap delivers consistent thread quality in demanding materials including high-tensile steel. It features 4 flutes, a plug chamfer for lead-in control, and a 6H thread class of fit with a D6/D7 thread limit. The overall length measures 4.331 inches (110 millimeters), and the shank diameter is 0.48 inches. Right-hand thread direction and a 2.00 mm pitch are standard for this M16 x 2 configuration. It belongs to the Guhring Series 4122 product line and is intended for use without coolant through the tool body.

This tap is suited for through-hole threading operations in production and maintenance environments where M16 x 2 metric coarse threads are required. Its powdered metal construction and TiN finish make it appropriate for use in high-tensile steel workpieces where wear resistance and edge retention are priorities. Machinists, tool-and-die technicians, and maintenance professionals working in industrial or manufacturing settings are the primary installers and users of this tool.

Key Features

• M16 x 2 metric coarse thread form with 6H class of fit and D6/D7 thread limit
• Powdered metal construction for improved wear resistance in hard and high-tensile steel
• TiN coating reduces friction and extends tool life in abrasive materials
• 4-flute spiral point geometry pushes chips forward, suited for through-hole applications
• Plug chamfer provides a controlled lead-in and is standard for most through-hole tapping setups
• Right-hand thread direction, 4.331-inch OAL, 0.48-inch shank diameter — fits standard tap holders for M16 sizing

Compatibility

Designed for through-hole tapping of M16 x 2 metric coarse threads. Rated for use in high-tensile steel. Compatible with standard tap holders and machines accepting a 0.48-inch shank diameter. No coolant-through requirement.

Installation Notes

This tap should be installed by a qualified machinist or tooling technician using a properly sized tap holder or CNC toolholder rated for the shank diameter. Ensure the workpiece is securely fixtured and the spindle is aligned before beginning the threading operation. Use an appropriate cutting fluid or tapping lubricant for high-tensile steel to reduce heat and extend tool life. Inspect the tap for chipping or wear before each use and replace if edge condition is compromised.
