Guhring 9039600120000 Spiral Point Tap M12 X 1.75

Product Description

The GUHRING 9039600120000 is a cobalt spiral point tap designed for through-hole threading in metric applications. It cuts an M12 x 1.75 thread profile to a 6H class of fit and carries a D5/D6 thread limit for consistent tolerance control. The plug chamfer style makes it well suited for through-hole work where the tap can advance ahead of the cut threads. A MolyGlide coating reduces friction and heat buildup during the threading operation, extending tool life across a range of workpiece materials. Machinists and tool-room technicians working on manual machines or CNC setups will find this tap a direct-fit choice for production threading in the M12 range.

This tap is intended for through-hole threading in a wide range of materials including steel, aluminum, gray cast iron, malleable iron, spheroidal iron, and non-ferrous metals. Its right-hand thread direction and cobalt construction make it appropriate for both general production environments and job-shop applications where a durable metric tap is needed. The Series 3960 designation places it within a standard product family for professional tooling applications.

Key Features

• M12 x 1.75 metric thread form with 6H class of fit and D5/D6 thread limit for repeatable tolerance
• Cobalt construction provides heat resistance and hardness for threading in steel and cast iron
• MolyGlide finish reduces friction and galling, extending service life in high-volume runs
• Plug chamfer style optimized for through-hole threading applications
• 3-flute design balances chip evacuation with core strength in the M12 size range
• No coolant-through requirement simplifies use on standard machines without internal coolant

Compatibility

Designed for through-hole threading in steel, aluminum, gray cast iron, malleable iron, spheroidal iron, and non-ferrous metals where an M12 x 1.75 metric thread is required.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with tapping operations and cutting tool safety. Secure the workpiece and ensure proper alignment before beginning the threading cycle to avoid tap breakage. Apply an appropriate cutting fluid for the workpiece material even though coolant-through is not required. Follow shop safety protocols and machine manufacturer guidelines when operating tapping equipment.
