Guhring 9048853054860 Spiral Point Tap 12-24 Unc

Product Description

The GUHRING 9048853054860 is a spiral point plug tap designed for right-hand through-hole threading in steel applications. Built from HSS-E cobalt steel and finished with an Ignator coating, this tap handles demanding threading operations where heat and wear resistance matter. It cuts a 12-24 UNC thread to a 2B/3B class of fit with an H3/H4 thread limit, giving machinists and tool room professionals the dimensional accuracy required for standard fastener applications. The overall length is 2.382 inches, the thread length is 0.630 inches, and the shank diameter is 0.220 inches.

This tap is suited for through-hole threading in steel workpieces in both production and maintenance environments. The spiral point geometry pushes chips forward ahead of the cutting action, making it effective in through-holes where chip evacuation matters. With 3 flutes and a plug chamfer, it is appropriate for starting threads from the top of a through-hole without requiring a pre-formed lead. It is commonly used in machine shops, maintenance facilities, and manufacturing lines where 12-24 UNC threads are a standard requirement.

Key Features

• HSS-E cobalt construction provides elevated heat and wear resistance during steel threading
• Ignator coating reduces friction and extends tool life in ferrous materials
• Spiral point geometry pushes chips forward, optimizing performance in through-hole applications
• Plug chamfer allows threading to begin at the top of a through-hole without a pre-formed entry
• H3/H4 thread limit holds 2B/3B class of fit tolerances for standard UNC fastener compatibility
• Right-hand cut, no coolant-through requirement, and no interrupted thread geometry for straightforward setups

Compatibility

Designed for through-hole threading of 12-24 UNC threads in steel. Suited for use with standard tap holders and machine tapping equipment that accept a 0.220-inch shank diameter.

Installation Notes

This tap should be installed by a machinist or toolroom professional familiar with tapping operations and proper speeds and feeds for cobalt tooling in steel. Secure the tap in a rigid or floating tap holder appropriate for the machine and application. Ensure the workpiece is fixtured firmly and the hole is properly drilled and chamfered before tapping begins. Follow shop safety procedures and use appropriate cutting fluid for steel to maximize tool life.
