Features and Benefits
NPT (National Pipe Taper) refers to American National Standard Taper Pipe Threads. They are commonly used for general purpose applications and require a sealant.
High Speed Steel (HSS) provides good wear-resistance and can be used in general purpose applications for both ferrous and non-ferrous materials.
V is a multi-layered TiCN coating, It is commonly used on carbon, mild steels, aluminum castings and cast iron. V is a proprietary coating exclusive to OSG Tap and Die, Inc.
Spiral flute taps are used for threading blind holes in aluminum, brass and softer steels. The flute geometry draws the chips away from the hole where chip disposal may be an issue.
