A fixed rotary drill bit, especially the type rotary drill bits incorporating a plurality of spaced polycrystalline diamond compact (pdc) cutters or cutting elements on a plurality of radial blades, includes multiple tungsten carbide inserts (tci) spaced between the pdc cutters or cutting elements, each tci providing a mitigation to vibration for the drill bits, rapidly adapting the tcis by wear from the intermediary formation ridges created from drilling resulting in the creation of a unique kerf in each tci, thus increasing stability of the bit from lateral instability, making the drill bit more efficient, and promoting a continual steady state of drilling.. .

Metal object with diamond-like carbon film and method for forming diamond-like carbon film
A metallic film formation target which is an object on which a diamond-like carbon film is to be formed is placed in a flow channel through which film formation gas containing methane gas flows. The film formation gas is caused to flow at a predetermined flow rate through the flow channel during the process of raising the temperature of the film formation target from room temperature to a predetermined temperature.
