Shipping&packing
Steel teeth or carbide inserts come in a variety of shapes, sizes, and grades of tungsten carbides to address specific drilling conditions. TCI bits offer increased durability over steel tooth bits but also carry a higher cost. Open bearing bits feature bearings without a seal that are open to outside debris.
