Pro-Tip: To maximize the lifespan of your step bits when drilling into stainless steel or thick metal, always use a slow drill speed and apply a small amount of cutting fluid or lubricant. This significantly reduces friction and heat buildup, keeping the cutting edges razor-sharp for hundreds of additional holes.
