Osg 1760601 Spiral Point Tap 10-32 Unf Plug 3 Flute

Product Description

The OSG 1760601 is a spiral point tap designed for threading 10-32 UNF internal threads in demanding material applications. Built from powdered metal with a steam oxide coating, this plug-style tap is engineered for use in materials that resist standard high-speed steel tooling. The spiral point geometry pushes chips forward ahead of the tap, reducing clogging in through-hole applications. With 3 flutes and an H6 thread limit, it holds tight tolerances appropriate for precision fastener threads. Overall length is 2.374 inches with a 0.5-inch thread length and a 0.194-inch shank diameter. It is suited for use in CNC machining centers, drill presses, and tapping arms in production and job-shop environments.

This tap is rated for use in hardened steel, stainless steel, high-nickel alloy, titanium, alloy steel, and die steel. The steam oxide finish provides moderate lubricity and corrosion resistance during the tapping operation, which is particularly useful when cutting fluids are limited. The plug chamfer — typically 3 to 5 threads — allows easy thread starting and is appropriate for through-hole tapping operations. Machinists, tool-and-die makers, and maintenance technicians working with precision threaded assemblies in aerospace, industrial, and OEM production settings are the primary users of this tap.

Key Features

• Spiral point design pushes chips forward for clean through-hole tapping
• Powdered metal construction for improved wear resistance over standard HSS
• Steam oxide coating provides lubricity and light corrosion protection
• H6 thread limit holds tight tolerance for precision 10-32 UNF threads
• Rated for hardened steel, stainless steel, titanium, and high-nickel alloys
• Plug chamfer for straightforward thread starting in through-hole applications

Compatibility

Designed for through-hole tapping of 10-32 UNF threads in hardened steel, stainless steel, high-nickel alloy, titanium, alloy steel, and die steel workpieces.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician using a tapping arm, CNC machine, or drill press with appropriate feed control. Always use cutting fluid or tapping compound rated for the workpiece material, particularly when threading stainless steel or high-nickel alloys. Ensure the tap is properly aligned to avoid cross-threading and tap breakage. Inspect the tap for wear regularly, as powdered metal taps in hard materials can fail without visible warning if overloaded.
