10 Best Drill Bit Sets in 2026

With 212 pieces, this set is the workshop equivalent of a well-stocked toolbox. It hands you a drill or driver bit for nearly any material, wood, stone, or metal, and for a huge range of screw heads. The comprehensive selection means you’ll spend less time hunting for a specific bit and more time working, making it a logical first set for a serious DIYer or a pro who wants a reliable backup. The organized plastic case keeps everything in one place, though its contents are broad rather than deep in any single specialty.

With 212 pieces, this Makita set covers a wide range of drilling and driving tasks in wood, stone, and metal. That extensive equipment comes with a weight of 9.3 pounds, making it a kit for a workshop bench rather than a lightweight carry-along. Its value lies in being a foundational collection that can handle many common jobs, supplied in a handy plastic carrying case for organized storage.

Covering sizes from 1/16-inch to 1/2-inch, this 21-piece set handles most common drilling tasks in wood, metal, and plastic. A titanium nitride coating and tapered web construction are designed for longer life and greater durability to reduce breaking. The included sizes provide a practical range for general workshop use.

This set offers a focused selection of jobber-length bits with a pilot point that starts on contact for cleaner holes, and no-spin shanks. Its compact plastic case measures 8.8 inches in length and width, keeping the organized set portable. For drilling common materials, the titanium nitride coating aims to provide longer life than basic high-speed steel.

This drill bit set is impact-rated for 1/4-inch hex drivers, so it’s engineered to withstand the concussive force from an impact driver. The titanium nitride coating lasts 2.5 times longer than non-coated bits, which means less frequent replacement during demanding jobs. A 135-degree split point geometry provides faster starts and reduced walking for drilling into ferrous metal, wood, plastic, non-ferrous metal, cast iron, and stainless steel.

The 14-piece set offers a focused range of sizes for common tasks rather than a comprehensive workshop collection. Its compact case measures 6.3 inches wide and weighs 1.1 pounds, making it easy to store with an impact driver. These bits are designed for drilling into multiple material types, potentially reducing the need for multiple dedicated sets on some job sites.

The 8% cobalt alloy construction is the key here, letting these bits withstand the intense heat generated by drilling into stainless steel or cast iron without losing their edge. That makes this Bosch set the go-to for mechanics, metal fabricators, or any DIYer tackling a project involving hard alloys. The split-point tips bite in immediately to prevent dangerous skating, and the three-flat shank ensures the bit won’t spin in your chuck when the going gets tough. It’s built for a specific, demanding job.

This 21-piece set is built specifically for drilling into hard metals like stainless steel, cast iron, and titanium, so it’s a specialized choice for metalworking. For a more versatile kit that handles wood and masonry, the Bosch MS4034 is an alternative for general tasks. The CO21B’s value comes from its M42 cobalt alloy, which Bosch states delivers 10x the life of standard bits for high heat resistance in tough materials.

Weighing just one pound and packed into a case the size of a small lunchbox, the Bosch MS4034 is built for the person who needs to tackle a dozen different tasks in a dozen different places. Its tough storage case provides secure and organized portability. The removable components let you take only the bits you need for carry-along convenience. The set includes brad point bits, rotary masonry drill bits, and driver bits for applications in wood, metal, and masonry, which Bosch states makes it ideal for everyday tasks from the garage to the workshop to the home.

This mixed set is designed as a generalist for drilling and fastening in wood, metal, and masonry. For prolonged drilling in hard metals, a dedicated set such as the Bosch CO21B Cobalt uses a cobalt-alloy construction for extreme heat resistance. The Bosch MS4034 includes a wide variety of both driver bits and drill bits, so for the majority of mixed-material projects, the right tool is within arm’s reach.

The comprehensive 1/64″ increments from 1/16″ to 1/2″ mean you can tackle nearly any metal drilling job with the exact size you need, eliminating guesswork and stepped drilling. This set is for the fabricator or mechanic who regularly faces tough alloys. Its M35 cobalt composition and wear-resistant gold oxide finish translate directly to less heat buildup and fewer trips to the sharpening station. It’s a focused, professional-grade kit built for durability over a wide range of common sizes.

The trade-off is in its specialization. You’re getting a heavy-duty round case full of metal-piercing bits, but nothing for wood or concrete. If your projects are strictly in hardened metals, this set covers the bases thoroughly. For mixed-material work, a kit like the Bosch MS4034 offers broader utility, though with less focused performance on tough alloys. The Drill America set excels by doing one job exceptionally well, making it a logical choice for a dedicated metalworking bench.

Cobalt construction allows this 29-piece set to handle tough materials like stainless steel and cast iron, resisting dulling better than standard bits. The variable helix flute design, noted in expert round-ups for high performance, helps clear chips efficiently during deep cuts in metal. This kit is built for projects that start with metal stock and end with a pile of curly chips, suiting tradesmen and dedicated hobbyists who need reliable penetration in hardened materials.

Its substantial case size reflects its focused application. While excellent for its intended purpose, it’s overkill for someone who just needs to hang drywall or assemble furniture. For general-purpose drilling across wood, plastic, and light metal, a more compact mixed set like the Bosch MS4034 covers more bases in a smaller footprint. The Milwaukee set earns its keep in a metal shop, not a general tool bag.

With 230 bits spanning from 3/64-inch up to a full 1/2-inch, this set covers an enormous range of hole sizes in fine increments. For a serious DIYer or a shop that frequently tackles varied projects, having the right size on hand without a trip to the store is a major time-saver. The titanium coating on the high-speed steel adds durability and helps manage heat during extended use. It’s a logical choice for someone who drills into the mix of wood, plastics, and softer metals listed and values comprehensive coverage above all else.

The trade-off for that variety is bulk. The hard case is nearly a foot long and over two inches thick, so it won’t tuck into a small drawer or a compact tool bag. For focused, repetitive metalwork, a specialized set like the Bosch CO21B Cobalt might offer better performance in hardened steels. But if your workbench sees a constant rotation of different materials and hole requirements, this Hurricane set acts as a complete, standalone drill bit library.

The 135-degree split point tip bites into material immediately, which helps reduce walking on surfaces like metal or hardwood. A tapered web design increases durability and resists breakage where bits are weakest. Larger bits feature a 3-flats shank to reduce spin-out in the chuck, and size markings on each shank allow for quick identification.

The high-speed steel construction is intended for use in plastic, wood, and metal. For frequent drilling in harder alloys, a dedicated cobalt set such as the Bosch CO21B is listed. The 14-piece assortment covers essential sizes, while larger kits like the 34-piece Bosch MS4034 offer a broader range.

A carbide tip built through a unique brazing process means this bit chews through tile, masonry, and even metal without dulling quickly. That’s the core of its multi-material claim. For a contractor or serious DIYer who regularly switches between substrates and needs a bit that can handle the abuse of a hammer drill, this set delivers longer life. The optimized flute design removes dust faster, which keeps the carbide tip cooler for sustained strength during demanding jobs.

This is a specialized 5-piece set for demanding, mixed-material drilling, not a comprehensive collection for every shop task. If your workbench needs a broad assortment of bits for precise metalwork or detailed wood projects, you’ll want a larger general-purpose set like the DeWalt DW1361. But for punching clean holes through stubborn materials with a single, reliable bit, these Diablo carbides are hard to beat.
