10 Best Drill Bits For Metal 2025 in the United States

The DEWALT 14-Piece Drill Bit Set is versatile and designed for use on metal, plastic, and wood. One of its key strengths is the 135-degree split point tip, which reduces bit walking, ensuring precise starts and cleaner holes. Made from high-speed steel, these bits are durable and can handle the rigors of metal drilling. The black and gold coating not only gives a sleek look but also helps prevent rust and wear, extending the life span of the bits. The tapered web design adds to the durability, making these bits less prone to breaking under pressure.

Additionally, the 3-flats shank ensures a tighter grip in the chuck, reducing spin-out and improving control during use. The bits come with size markings for quick identification, which is a handy feature for those who need to switch bits frequently. However, the set's broad application for wood and plastic in addition to metal might imply that they are not specialized exclusively for metal drilling. For professional metalworkers who need bits designed specifically for metal, this could be seen as a drawback.

Additionally, the set's relatively higher price point might be a consideration for budget-conscious buyers. This DEWALT set is a solid, multi-use drill bit set that offers durability, precision, and ease of use, making it a good choice for DIY enthusiasts and general contractors.

The DEWALT Titanium Nitride Coated Drill Bit Set, Pilot Point, 21-Piece (DW1361) is designed for efficient and precise metal drilling. The titanium nitride coating enhances durability and reduces wear, ensuring a longer lifespan for the bits. The pilot point design starts on contact, creating cleaner holes and improving accuracy, which is particularly beneficial for metal work.

The 135-degree point angle aids in reducing walking and ensures better drilling performance, allowing you to start drilling without the bit wandering off the mark. The straight shank type combined with a tapered web provides greater durability and reduces breaking risks, making these bits reliable for tough jobs. The set includes a range of sizes from 1/16-inch to 1/2-inch, accommodating various drilling needs and applications. Additionally, the bits come in a plastic tough case for organized storage and easy transport.

While the titanium nitride coating adds to the durability, it might be overkill for users with light-duty drilling needs. The spiral flute design helps with chip removal but may not be the best for softer materials. These drill bits perform optimally on metal, plastic, and wood, but for specialized tasks, users might need to look for more specific drill bit sets. With a 30-day money-back guarantee, the DEWALT DW1361 set is a strong contender for anyone needing reliable and durable drill bits for metal.

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.
