Osg 1208800 Spiral Point Tap 10-32 Unf 2 Flute Hss

Product Description

The OSG 1208800 is a spiral point tap designed for cutting internal threads in a wide range of metals. It features a 10-32 UNF thread form with a plug chamfer, 2 flutes, and a right-hand thread direction. Manufactured from high-speed steel with a bright finish, this tap carries a Thread Limit of H2 and a Class of Fit of 3B. The overall length is 2.375 inches with a thread length of 0.54 inches, making it a compact, standard-profile tap suited for production and maintenance threading operations. Licensed machinists and tool-and-die professionals are the primary users.

This tap is applied in threading operations across both shop and field settings. It is suited for use in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel workpieces. The plug chamfer distributes the cutting load across several leading threads, making it a practical choice for through-hole applications where chip evacuation is a priority. The spiral point design pushes chips forward ahead of the tap rather than packing them in the flutes, which reduces the risk of tap breakage in production runs.

Key Features

• 10-32 UNF thread form with right-hand direction for standard inch-series threading
• Plug chamfer distributes cutting load and suits through-hole applications
• Spiral point geometry pushes chips forward, reducing clogging in production use
• High-speed steel construction provides wear resistance across a broad material range
• H2 thread limit and 3B Class of Fit for controlled tolerance threading
• Bright finish with no coolant-through requirement, compatible with standard cutting fluids

Compatibility

Compatible with aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel workpieces requiring a 10-32 UNF internal thread. Designed for use in standard tap holders and tapping heads that accept a 0.194-inch shank diameter.

Installation Notes

This tap is installed by machinists, tool-and-die technicians, and maintenance mechanics using standard tapping equipment. Secure the workpiece fully before starting and confirm spindle alignment to avoid tap deflection and breakage. Apply an appropriate cutting fluid for the workpiece material to extend tool life. Follow standard speeds and feeds for high-speed steel taps in the material being threaded.
