Review on Shark Industries PN-12704 Die Grinder Cut Off Wheels - 10 Pack, 3-Inch x 1/16” x 3/8” Shark Type-1 Double-Reinforced Thin Wheels, 54 Grit, 25,000 RPM Max (10 Cutting Discs) by Mirzet Gosselin

I like these. Affordable and keeps a decent time. They are made in the USA and give a thin and clean cut. I have found that I can run them a little longer before they overheat compared to others. If you want to set up a simple water cooling station for your cutting tool, try this: Get a water bottle and some duct tape. Poke a small hole in a water bottle. Take a 3/8 inch vinyl tube (soft) and slide it through, wrap it with tape and pull to make sure it is snug. Take a hose clamp: https://www.amazon.com/Small-Shut-Off- Hose-Clamp/dp/B00A2VF9N0/ref=sr_1_8?ie=UTF8&qid=1519338013&sr=8-8&keywords=tube+clamp Hang the bottle up, line up the pipe with hanging wire and stool! For a long time. If you want to go even further, you'll find a small aquarium pump, a hose that bends and holds in place, a hanging water bottle, and a waste water return. I did it in the field so don't worry about going back first. However, the hassle with the stored discs and smoking is worth it!
