10 Best Metal Drill Bits

The DEWALT DW1354 14-Piece Titanium Drill Bit Set is designed to work well on metal, featuring a titanium nitride coating that helps the bits last longer by reducing wear. This coating also provides a smooth, silver finish that helps reduce heat during drilling. With 14 sizes ranging from 1/16 inch to 1/2 inch, this set covers a good range for most general metal drilling tasks. The bits include a pilot point tip that starts drilling precisely on contact, resulting in cleaner and more accurate holes without slipping.

The no-spin shank style helps keep the bit stable in the drill chuck, reducing the chance of the bit spinning inside and improving safety and control. Additionally, the tapered web design adds extra strength to the bit, making it less likely to break when drilling tougher materials. The flute design, which helps clear out metal shavings, is standard—efficient but not optimized for high-speed drilling on very thick metal.

This set is well-suited for lighter to medium drilling jobs on metal. For very hard metals or heavy industrial use, specialized bits might be required. The DEWALT DW1354 is a reliable and versatile drill bit set suitable for DIYers or anyone needing durable bits for everyday metal projects.

The Bosch Professional 25-piece HSS-Cobalt ProBox drill bit set is designed specifically for drilling into tough metals like stainless steel. Made from a cobalt alloy mixed with high-speed steel, these bits are built to resist wear and handle heat better than standard bits, which helps them last longer during demanding tasks. The gold finish also suggests some level of additional coating to reduce friction and improve durability. With a 135-degree tip angle, the bits are optimized for clean and precise starts, reducing the chance of slipping on smooth metal surfaces. The bit sizes range from 1 mm to 13 mm, covering many common drilling needs, and their round shank fits standard three-jaw drill chucks, making them easy to use with most drills. The two-flute design helps efficiently remove metal chips, which keeps the bits cooler and extends their life.

This set is particularly suited for those who need reliable, long-lasting bits for stainless steel and other hard metals, whether for professional work or serious DIY projects. Because the shank is cylindrical, it may not fit some quick-change drill chucks that require hex shanks. Also, while the set offers a wide range of sizes, users drilling softer metals or wood might not need such specialized bits, which tend to be pricier than general-purpose sets.

The well-rounded design and durable materials make this Bosch set a strong choice if your main focus is metal drilling, especially stainless steel, though casual users with lighter jobs might find more affordable options sufficient.

This 19-piece drill bit set features high-quality M42 cobalt steel with 8% cobalt, making the bits very hard and heat-resistant. This means they stay sharp longer and handle tough jobs like drilling stainless steel and other hard metals, which is a big advantage if you work with challenging materials. The bits come in a useful range of sizes from 1mm up to 10mm, increasing in small steps, so you can pick the exact size you need for precise work.

They have a 135-degree split point tip, which helps start drilling quickly and prevents the bit from slipping on the metal surface. The straight shank design fits most standard drill chucks, making these bits easy to use with common drill tools. The cutting edges are designed to produce long metal strips (chips) rather than grinding slowly, which means faster and cleaner drilling. The polished finish helps reduce friction and heat build-up during use.

Although these cobalt bits cost more upfront than regular drill bits, they often last much longer and can drill faster, reducing the overall cost per hole if you do a lot of metal drilling. If you only occasionally drill soft materials or wood, these bits might be more than you need and could be less cost-effective. This set is ideal for serious DIYers or professionals who frequently drill hard metals and want durable, reliable bits that perform well under demanding conditions.
