Step drill bit set8/16/2023 However, combination sets are available that offer wood, steel, and masonry drill bits in the same case. Normally, you'll buy a drill bit set that contains the same type of drill bit in various sizes. Diamond-coated drill bits are used for two very different tasks: drilling glass and making large holes in concrete and cinder blocks.Titanium-coated drill bits are equally popular and similar in performance to black oxide, but these are gold in color. Buy from a reputable brand and you should avoid this problem.īlack oxide-coated drill bits resist corrosion and are more durable. We would avoid cheap black oxide or titanium drill bit sets because the surface coating will soon wear through, and all you'll be left with is HSS. The important thing with any coated drill bit is the thickness of the coating. It's normally found on good-quality masonry, tile, and glass drill bits. Tungsten carbide (often just called carbide) is a tough ceramic bonded onto the end of an HSS shank. You pay a premium, but these are far and away the best drill for steel and will cut effortlessly through wood, aluminum, fiberglass and most composites. The cobalt becomes part of the drill bit's structure rather than a coating, so they last much longer. These bits stay sharper longer.Ĭobalt is alloyed with HSS to produce very hard drill bits. The chrome resists corrosion, and in combination with vanadium it creates a harder metal than HSS. HSS is at the core of almost all other drill materials, too.Ĭhrome vanadium steel is used for some drill bits. It's used for all kinds of cutting tools because it's cheap, relatively tough, and easy to sharpen. High-speed steel (HSS) is the most common material for drill bits. Steel, tile, brick, concrete, and glass require different approaches. They will cut wood, plastics, aluminum, brass, and fiberglass with varying degrees of effectiveness. The right information will make your choice much easier, and that includes two things: what the drill bits are made of and what each drill bit is used for.Īll of these materials will be found in general-purpose drill bit sets. There’s a bewildering array of drill bit sets available, but one important thing to remember is that you want the right drill bit for the job. Too large and it will pull straight back out as soon as any load is put on it. Too small and you won't get the anchor in. When using wall plugs or anchors, it's important to match drill bit size precisely.
