Osg 1207200 Spiral Point Tap 5-44 Unf 2 Flute Hss

Product Description

The OSG 1207200 is a spiral point plug tap designed for threading 5-44 UNF holes in a wide range of metals. Manufactured from high-speed steel with a bright finish, it operates in right-hand thread direction with a 2B class of fit and an H2 thread limit. The spiral point geometry pushes chips forward ahead of the cutting action, making it well-suited for through-hole tapping operations where chip evacuation is critical. This tap features 2 flutes and is sized for use in light production and maintenance environments where precise, clean threads are required.

This tap is intended for threading ferrous and non-ferrous metals including aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. It is commonly used in machine shops, toolrooms, and field maintenance settings. The 5-44 UNF thread specification places it in fine-thread applications typical of small fasteners found in instrumentation, electronics enclosures, and precision assemblies.

Key Features

• Spiral point design pushes chips forward for clean through-hole threading
• High-speed steel construction provides durability across a broad range of workpiece materials
• Bright finish - no coating - suited for use with cutting fluids on a variety of metals
• 2B class of fit delivers standard commercial thread tolerances
• H2 thread limit for consistent fit in close-tolerance applications
• Right-hand thread direction, plug chamfer for easy thread starting

Compatibility

Designed for tapping 5-44 UNF threads in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel workpieces.

Installation Notes

This tap is installed by machinists and maintenance technicians using a tap wrench, tapping head, or CNC spindle. Always ensure the workpiece is securely fixtured and the tap is properly aligned to the drilled hole before engaging. Apply an appropriate cutting fluid for the workpiece material to reduce heat and extend tool life. Power down any powered equipment fully before hand-tapping operations in the field.
