Because it is sharp, please use it vertically.

Regular ironwork drills temporarily heat resistant with titanium coating, but the blade will not wear out and cut before the blade is hot and the result is a higher coefficient of wear and burn.Stainless steel is harder and more sticky than ordinary iron, so when used for work, we recommend Cobalt Hiss (HSS-CO) that is harder and more resistant to wear and tear.
