Best Drill Bits for Metal of 2026

This DeWALT set consistently tops the charts for good reason. It balances performance, durability, and price better than most competitors. If you need a reliable “do-it-all” set for your toolbox, this is the one to grab.

The bits feature a titanium coating, which reduces friction and heat buildup. This keeps the cutting edge sharper for longer compared to standard black oxide bits. DeWALT also uses a “pilot point” tip design. This prevents the bit from skating across the metal when you start the hole, meaning you often won’t need a center punch.

The shanks are ground flat to stop them from spinning inside the chuck, a common annoyance with round-shank bits. For general repairs and DIY metal projects, this 14-piece set covers all the standard sizes you are likely to need.

If you need a wider range of sizes without breaking the bank, this 20-piece DeWALT set is a solid choice. The black oxide coating provides decent corrosion resistance and helps reduce friction during drilling.

These bits utilize a 135-degree split-point tip. This geometry is excellent for metal as it bites in immediately and creates smaller chips. The parabolic flute design improves strength, making the bits less likely to snap under torque compared to standard designs.

The value here is strong for the size count. They aren’t as hard as cobalt, but for general mild steel, wood, and plastic, they are dependable workhorses.

For drilling sheet metal or enlarging existing holes, nothing beats a step bit. This Neiko set gives you the capability of 28 different bit sizes in just three tools. It is incredibly efficient for electrical work or automotive body repairs.

The bits are made from high-speed steel with a titanium coating to help shed heat. The 135-degree split point allows you to start holes without a pilot bit. The tri-flat shank design is a great feature, locking the bit securely into your drill chuck so it won’t slip under load.

Keep in mind that step bits are difficult to sharpen. However, for clean holes in thin materials, they are indispensable.

When you hit hardened steel that chews up ordinary bits, only carbide gets through. This ALFA Tools set gives you 13 solid tungsten carbide jobber bits in graduated fractional sizes, so the whole body is carbide rather than an HSS shank with a brazed tip. The hardness runs end to end, which is what lets carbide cut material that stops plain HSS and cobalt cold.

The 118-degree point is ground to start accurately and resist wandering. Solid carbide is suited to hardened and stainless steel, cast iron, and similar high-tensile metals, and because it shrugs off heat far better than HSS, it holds an edge where coated bits give up. A drop of cutting oil still extends its life.

The catch is that carbide is hard but brittle, with almost no flex before it shatters. It needs a rigid setup: a drill press or a clamped workpiece and a steady hand. Any sideways wobble in a handheld drill can snap a bit, so this is a precision set for the jobs nothing else will touch, not an everyday driver bit.

Irwin is a heavyweight in the tool industry, and this M-35 cobalt set shows why. Containing 5% cobalt, these bits are specifically engineered for drilling abrasive, hard metals like cast iron and stainless steel.

This is a massive 29-piece set, covering almost every size you could need in a workshop. The 135-degree split-point tips cut aggressively with less pressure required. Because of the cobalt content, they resist the high heat that destroys standard HSS bits.

It is pricier than a standard oxide set, but if you work with tough metals regularly, the longevity of these bits pays for itself.

If you primarily use an impact driver, this Makita set is designed for you. Each bit features a 1/4-inch hex shank, allowing them to snap directly into impact drivers for quick changes. You don’t need a standard drill chuck.

The titanium nitride coating extends the life of the bits by up to 2.5 times compared to uncoated options. They feature a 135-degree split point to prevent walking. This is a versatile kit with sizes ranging from 1/16-inch to 1/2-inch.

While convenient, be careful using impact drivers for drilling metal. The hammering action can sometimes be too aggressive for smaller bits, causing them to break.

When you just need a dependable set for everyday repairs without spending much, this DeWALT DWA1184 kit is the value pick. It packs 14 high-speed steel bits from 1/16-inch to 1/2-inch, a wider span than most budget sets that stop at 1/4-inch.

What lifts it above bargain-bin bits is the geometry. Each bit has a 135-degree split-point tip that bites on contact and cuts down on walking, plus a tapered web that adds strength so the bit resists snapping under torque. The black and gold oxide coating helps fend off rust, and the larger sizes get a 3-flat shank that grips the chuck instead of spinning.

It is still plain HSS, so it is best on mild steel, aluminum, wood, and plastic rather than stainless or cast iron. Reviewers note the largest bits can struggle in thick metal if you push too fast or skip cutting oil. For a homeowner’s drawer or light fabrication, the value is hard to beat.
