Drill multiple size holes with one bit! Allstar Performance step drill bits will drill sheet metal and aluminum without deforming or distorting. The bits start on contact, de-burr and chamfer while drilling, and do not require a center punch. They’re machined from high-speed steel, with a titanium nitride coating. Both step drill bits have a ¼” shank, and enable you to drill holes ranging from ¼” to 1⅜”.
