10 Best Drill Bits For Metal 2026 in the United States

The BOSCH CO14B 14-Piece Assorted Set is a solid choice for those needing reliable drill bits for various metal applications. Made from Cobalt M42 material, these bits are known for their durability and high heat resistance, making them particularly suitable for tough materials like stainless steel, cast iron, and titanium.

The enhanced M42 alloy contains 8% cobalt, which significantly extends the lifespan of the bits compared to standard options. The thick web-helix design further adds stability, which is beneficial for drilling through hard substances without bending or breaking the bits. The set includes a range of sizes from 1/16" to 1/2", ensuring versatility for different drilling needs. With a 135-degree cutting angle, these bits can quickly penetrate surfaces, and the three-flat shank design helps prevent slippage in the drill chuck.

While the titanium finish increases corrosion resistance, it may not be as durable as some other coatings. Additionally, these high-quality bits come with a higher price point, which might be a consideration for those on a budget. The included case keeps everything organized, which is a handy feature for storage and transport. If you're working on demanding metal drilling projects, this set from Bosch is worth considering.

The Drill America 29 Piece Cobalt Stepped Point Drill Bit Set is a solid choice for anyone needing to drill through metal and other tough materials like acrylic and brass. Made from cobalt, these bits are tougher and last longer than standard steel bits, especially when working with hard metals. The gold oxide finish helps reduce heat buildup, which means the bits stay sharper and cut more efficiently. The 135-degree split point is designed to start drilling quickly without wandering, making it easier to get precise holes.

The set includes a wide range of sizes from 1/16" up to 1/2", covering most common drilling needs in metalworking. The 3-flat shank design on larger bits prevents slipping in the drill chuck, although smaller bits have round shanks which might not grip as securely. One minor downside is that these bits are jobber length, which is standard but not ideal if you need extra-long bits for deeper holes. Also, since they are made in China, quality control might vary slightly, but Drill America has a good reputation.

This set comes in a convenient round case for organization and portability, making it useful for both hobbyists and professionals who often work with metal. For those who regularly drill various hole sizes in hard metals and want durable bits that stay sharp longer, this set is worth considering.

The Milwaukee 48-89-9254 SHOCKWAVE Step Bit is built from High Speed Steel (HSS), which is a solid choice for drilling into metal, offering good durability and strength. It features a Titanium Aluminum Nitride (TiAlN) coating that helps the bit last about five times longer than many other step bits, making it great if you plan to use it frequently. The 135-degree point angle and the Rapid Strike Tip ensure quick and accurate starts, meaning the bit is less likely to slip when you begin drilling. The spiral flute design helps clear metal shavings effectively, which keeps the bit cooler and reduces wear.

This bit covers multiple drill sizes with its 13-step design, and the laser-engraved markings make it easy to see the size you’re working with. It’s optimized for impact drivers and drill drivers, so it’s versatile with different tools. The bit’s cutting diameter maxes out at 0.88 inches, so it’s best suited for small to medium holes rather than very large ones. The hex shank means it fits securely in many types of drivers but might not work with some drill chucks that require round shanks.

This step bit is a strong choice for anyone working with metal who wants a durable, long-lasting tool that’s easy to control and reads sizes clearly, especially if you use impact drivers.
