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.
Steels such as A2, D2, S7, and other air-hardened tool steels with hardening temperatures in the 1,650- to 1,900- degree-F range will obtain a high hardness when the tools are pulled out from the coating bath into the air.
