OSG Spiral Flute Tap: 1/4"-20 UNC, H3 / 2B-3B, 3 Flute, Plug Chamfer

The OSG spiral flute tap is used for threading blind holes in materials such as steel and aluminum. Its spiral flute design pushes chips upward and out of the hole, preventing clogging. The TiCN coating reduces friction and extends tool life. It is commonly used in automotive, aerospace, and general manufacturing applications.

The OSG spiral flute tap MPN 1430008 has a thread size of 1/4"-20 UNC, with a thread tolerance of H3 / 2B-3B. It features 3 flutes, a plug chamfer, and is made from high-speed steel with a TiCN coating. This tap is designed for general-purpose threading in blind holes.

To select the correct OSG tap, match the thread size and pitch (e.g., 1/4"-20 UNC) to your hole specifications. Choose the chamfer type: plug chamfer for blind holes, taper for through holes. Consider coating like TiCN for harder materials. Always verify the thread tolerance class (e.g., H3 / 2B-3B) for fit requirements.
