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.
Titanium drill bits have a higher hardness level typically than cobalt drill bits. However, the titanium is a coating on the drill bit, so you wonât be able to sharpen the drill bit and keep the titanium coating. Both titanium bits and cobalt bits are more expensive than traditional HSS drill bits.
