Osg 1651506808 Spiral Point Tap 11/16-24 Unef Plug 2B

Product Description

The OSG 1651506808 is a spiral point tap designed for threading operations in a wide range of metallic workpieces. Part of the EXOTAP VC-10 Series 16515, it is ground from powdered metal and finished with a V coating to extend tool life and reduce friction during cutting. The tap features a plug chamfer, 3 flutes, and a right-hand thread direction in the 11/16-24 UNEF specification with an H4 thread limit and 2B class of fit. Overall length is 4.331 inches with a thread length of 1.2 inches. Machinists and tool-and-die professionals use this tap in production and maintenance threading applications.

This tap is suited for threading alloy steel, aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, medium-carbon steel, stainless steel, die steel, and hardened steel. The plug chamfer style makes it appropriate for through-hole threading where the tap can feed through the workpiece. It is commonly used in CNC machining centers, drill presses, and manual tapping setups where fine unified thread forms are required. Coolant-through capability is not included in this design.

Installation Notes

This tap should be installed and operated by qualified machinists familiar with threading tooling and proper speeds and feeds for the workpiece material. Secure the tap in an appropriate tap holder or chuck and ensure the spindle is properly aligned before engaging the workpiece. Power down the machine and remove the tap from the holder before making any adjustments or inspections. Follow applicable shop safety standards and tooling manufacturer guidelines for cutting fluid selection and application.
