Guhring 9039610127000 Spiral Point Tap 1/2-13 Unc

Product Description

The GUHRING 9039610127000 is a spiral point tap designed for through-hole threading in a wide range of ferrous and non-ferrous materials. Built from cobalt high-speed steel and finished with a MolyGlide coating, it delivers improved lubricity and extended tool life in production tapping applications. The plug chamfer style provides a standard lead-in suitable for most through-hole conditions. With 3 flutes and a right-hand thread direction, this tap cuts a 1/2-13 UNC thread to a Class 2B fit at H5/H6 tolerance. Overall length is 3.381 inches with a shank diameter of 0.367 inches. It is used by machinists and maintenance professionals in metalworking environments.

This tap is suited for through-hole threading operations in aluminum, gray cast iron, malleable iron, spheroidal iron, steel, and other non-ferrous metals. The cobalt construction makes it appropriate for harder or more abrasive materials where standard HSS taps may wear prematurely. The MolyGlide finish reduces friction during the cutting cycle, making it well-suited for both manual and machine tapping setups. It belongs to GUHRING Series 3961 and is packaged as a single unit.

Installation Notes

This tap is installed and operated by machinists or maintenance technicians using a tap wrench, tapping head, or CNC machine spindle. Ensure the workpiece is securely clamped and the tap is properly aligned with the pilot hole before beginning the threading cycle. Apply an appropriate cutting fluid or tapping compound for the workpiece material to protect the tool and improve thread quality. Follow standard shop safety practices and machine guarding requirements when operating any rotary cutting tool.
