![]() ![]() These bits run considerably more than black oxide, titanium, or even cobalt bits on average. We also frequently pop them into impact drivers to quickly get through various materials. We use these when drilling through combinations of wood, metal, tile, composites, and-of course-concrete. ![]() The carbide tips on the Daredevil Multi-Purpose Drill Bits are tough enough to cut through almost any material. Just like SDS-plus and SDS-max bits, these use tungsten carbide cutting tips. For that, our Pros consistently turn to Bosch Daredevil Multi-Purpose Drill Bits. When you start looking for the best concrete drill bits and the best masonry drill bits, the need for handling multiple materials arises. Hammer drills, however, more than suffice for drilling smaller diameter holes. SDS-Plus and SDS-Max rotary hammers do best for drilling on concrete and masonry materials. You can find the 15-piece kit for $34.97 or the 29-piece kit for $149.99. When you’re looking for the best cobalt drill bits for the money, the 15-piece kit presents a compelling option.

This new core design strengthens it with better flute durability. Milwaukee updated these bits with Enhanced Tapered Web. They also have a 135° QuadEdge Tip that helps it drill much faster than other cobalt bits we tested and still keep the walking to a minimum. Just like their titanium bits, they have the Red Helix variable flute design. High-Speed Steel (HSS) is a lower-cost drill bit good for drilling into soft steels, wood and plastic.Ĭobalt (HSCO) includes between 5 and 8% cobalt in the base, making it an excellent option for drilling into harder steel and stainless steel.Ĭarbide is the strongest drill bit for metal and is typically reserved for professional-grade tools.īlack Oxide is a coating added to HSS drill bits that helps reduce friction and speed up drilling through hard metals.The best drill bits for metal, and particularly for carbon steels, goes to Milwaukee for their excellent cobalt bits. Here’s a crash course on how to choose the best drill bit for metal: And don’t forget to always use your metal drill bit at low speed for the best results.
