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.
A bench grinder is easily one of the best ways to sharpen drill bits that are very worn, or even broken. If you drill through lots of hardwood or metal, or if you often hit masonry or nails with your twist drill bits, a grinder will put an edge back on them, fast. Most bench grinders come with two sharpening wheels, one coarse and one fine. You can do the bulk of the sharpening quickly using the coarse wheel. Then, move over to the fine wheel to put the finishing touches to the drill point. As you sharpen drill bits, a bench grinder makes it easy for you to dip the points briefly in water.
