Guhring 9048853111130 Spiral Point Tap 7/16-14 Unc

Product Description

The GUHRING 9048853111130 is a spiral point tap designed for through-hole threading in steel and similar ferrous materials. Built from HSS-E cobalt, the tap delivers the hardness and heat resistance needed for production tapping in tough workpiece materials. It features an Ignator coating that reduces friction and extends tool life in high-cycle applications. The plug chamfer eases entry into through-holes, and the 3-flute spiral point geometry pushes chips ahead of the cut rather than packing them in the flute. Thread limit is H5/H6 and the class of fit is 2B/3B, making it appropriate for standard unified thread tolerances used in general mechanical assembly.

This tap is used for cutting 7/16-14 UNC right-hand internal threads in through-hole applications. It is suited for machining centers, drill presses, and tapping heads where controlled feed is available. The spiral point design performs best in through-hole work where forward chip ejection is unobstructed. It is commonly specified for steel components in manufacturing, maintenance, and repair operations where UNC thread standards apply.

Key Features

• HSS-E cobalt construction for increased hardness and heat resistance in steel applications
• Ignator coating reduces friction and improves tool life in production tapping
• Spiral point geometry pushes chips forward, keeping flutes clear in through-hole work
• Plug chamfer style for standard through-hole thread entry
• 2B/3B class of fit for standard unified thread tolerance requirements
• Right-hand thread direction, no coolant-through required

Compatibility

Designed for through-hole threading of 7/16-14 UNC right-hand threads in steel and ferrous workpiece materials. Compatible with standard tapping chucks and holders sized for a 0.323-inch shank diameter.

Installation Notes

This tap should be installed by a qualified machinist or tool and die technician using a tapping chuck or rigid holder appropriate for the shank diameter. Ensure the spindle speed and feed rate are set to values recommended for cobalt taps in the workpiece material before beginning the cut. Use a cutting fluid compatible with steel to support chip evacuation and surface finish. Inspect the tap for wear or chipping between uses, as a damaged tap can produce out-of-tolerance threads or break in the workpiece.
