Guhring 9042850095250 Spiral Point Tap 3/8-16 Unc

Product Description

The GUHRING 9042850095250 is a spiral point tap designed for through-hole threading in a wide range of materials. Built from high speed steel (HSS) with a titanium nitride (TiN) coating, it produces 3/8-16 UNC threads to a Class 2B fit with H5/H6 thread limits. The plug chamfer geometry allows the tap to start and advance smoothly in through-hole applications. At 6 inches overall length with a 3-flute configuration, this tap is suited for production threading in machining, fabrication, and maintenance environments. Right-hand thread direction and no coolant-through design make it compatible with standard tapping setups.

This tap is intended for through-hole threading operations across a broad material range. It performs in aluminum, gray cast iron, malleable iron, spheroidal iron, non-ferrous metals, stainless steel, and steel. The TiN finish increases surface hardness and reduces friction, extending tool life in repetitive production use. It fits standard tap holders and machines used by machinists, tool and die makers, and maintenance technicians in light and heavy manufacturing environments.

Compatibility

Designed as an OEM-style replacement tap for standard 3/8-16 UNC through-hole threading applications. Compatible with aluminum, gray cast iron, malleable iron, spheroidal iron, non-ferrous metals, stainless steel, and steel workpieces as specified by the manufacturer.

Installation Notes

Installation and use of this tap should be performed by qualified machinists or maintenance technicians familiar with tapping operations. Secure the workpiece and ensure the tap is properly aligned with the drilled hole before beginning the threading operation. Use appropriate cutting fluid for the workpiece material to reduce heat and wear. Follow applicable shop safety practices and machine guarding requirements when operating tapping equipment.
