The Milwaukee Thunderbolt black oxide HSS bits are rated for drilling in steel as a primary material application. For best results in steel, use cutting fluid or oil to reduce heat buildup, drill at appropriate lower RPM for larger sizes, and apply steady consistent feed pressure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Are these impact-rated for use with impact drivers?\u003c\/strong\u003e\u003cbr\u003eA: No. These are standard jobber-length drill bits with a 3-flat shank designed for use in standard drill chucks—they are not impact-rated for use with impact drivers.
