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.
MolyGlide is a non-stick, low friction coating that has good sliding properties. It is commonly used for dry applications or where lubrication is minimal. MolyGlide is a proprietary coating exclusive to Guhring, Inc.
Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
