Features and Benefits
Modified bottoming is similar to bottoming, but the chamfer is longer and has more teeth. They are used for threading blind holes and have 2 to 2-1/2 threads.
Solid carbide provides better rigidity than high speed steel. It is extremely heat-resistant and used for high speed applications on cast iron, nonferrous materials, plastics and other tough-to-machine materials.
Diamond (PCD) coating is one of the hardest coatings. It is commonly used on concrete, fiberglass, plastic, stone, aluminum alloy and extremely difficult-to-machine materials.
