Air Hose With Blowgun Nozzle Dissipate Heat
Mark Hoover, Leitchfield, Ky.: “Any time you drill large holes in steel or hardmetal or have to machine steel on a lathe, you create a lot of extreme heat. And unless you work at a very slow speed, that heat can ruin drill bits and saw teeth. Adding cutting oil can help, but you have to use a lot of it which creates fumes and smoke.

Drill bits and saw teeth will instantly start to cut faster and smoother, and the metal stays cool and clean.”
