Features and Benefits
Plug chamfers are the most commonly used chamfer and are designed for efficiently threading through and blind holes. They have 3 to 5 threads.
Spiral point taps are used for tapping through holes. They have a flute geometry that shoots chips ahead of the cutting action to reduce loading and clogging within the flute.
elektraLUBE prevents welding, loading and galling between the tap and the workpiece. It is commonly used on stainless steels, high nickel alloys, aluminum and copper. elektraLUBE is a proprietary coating exclusive to OSG Tap and Die, Inc.
High Speed Steel (HSS) provides good wear-resistance and can be used in general purpose applications for both ferrous and nonferrous materials.
