Safe Levels of Fish Oil for Pets. The National Research Council has established a safe upper limit of EPA and DHA for dogs. It has yet to establish one for cats. In light of that, it is probably safe to use the guidelines for dogs for both species.
TTP Hard Drills, an easier way to drill steel and harder alloys - Cobalt Drill Sets and Cobalt Drills. Designed and developed from feedback from engineers in workshops TTP cobalt steel Hard Drills - drilling easily harder steels and metals where a normal HSS drill bit can not come close.
PDC drill bits. Polycrystalline diamond materials, for use in polycrystalline diamond compact (PDC) bits, are one of the most important material advances for oil drilling tools in recent years. Fixed-head bits rotate as one piece and contain no separately moving parts. When fixed-head bits use PDC cutters, they are commonly called PDC bits.
