OSG Spiral Point Tap: #1-72 UNF, H2 / 2B-3B, 2 Flute, Plug Chamfer

The OSG Spiral Point Tap #1-72 UNF is a general-purpose tap designed for through-hole threading in ferrous and non-ferrous materials. Its spiral-point design pushes chips forward, reducing chip clogging and enabling faster tapping. It is commonly used in precision machining, automotive, and aerospace applications where clean, accurate threads are required.

The OSG Spiral Point Tap has a #1-72 UNF thread size, H2 / 2B-3B tolerance, 2 flutes, plug chamfer, and black oxide high-speed steel construction. The manufacturer part number is 1205401. It is designed for through-hole threading and provides good wear resistance and lubricity from the black oxide finish.
