Steel is present in almost every construction. It’s a staple in buildings, homes, and even DIY projects that you have over weekends. But steel isn’t exactly metal as what many think. It’s an alloy of metal iron and carbon that has a bluish-gray finish. Even though it’s not pure metal, steel shares the same toughness with that of some materials like aluminum, titanium, zinc, and more. And so you might be wondering, what are the best drill bits for steel?
