9 Best Hss Drill Bits in 2026

The 135-degree split point is the star here. It bites immediately, so you don’t waste time chasing the bit across a curved surface or hardened metal. That feature, combined with the parabolic flutes for clearing chips, makes this set a reliable workhorse for the shop. It covers the most common sizes from 1/16-inch to 1/2-inch in metal, wood, and plastic. For the DIYer or pro needing a dependable, general-purpose set that just works drill after drill, this DeWalt collection hits the mark.

You trade some specialty size coverage for that focused reliability. Compared to a 29-piece set like the Irwin 3018005, you miss a few of the larger or less common fractional sizes. And while the black oxide coating adds durability, this is high-speed steel, not cobalt. For that brutal, all-day metalwork, you’d want a dedicated cobalt set. For everything else, this DeWalt set is the foundation your drill index needs.

A 29-piece set in 1/64-inch increments means you have the exact size for any standard bolt or tap, eliminating guesswork. That metal index case is the key here, keeping every bit securely in place and instantly identifiable, which saves time and frustration when you’re deep into a project. This set is built for the organized workshop where having the right drill bit on hand and protected matters more than fitting it in a pocket.

The trade-off is bulk. That sturdy metal case adds significant size and weight compared to a compact plastic index. For a portable kit, the DEWALT DWA1181 is a far slimmer profile. But if your bits live on a shelf or in a stationary toolbox, the IRWIN’s case offers superior protection and accessibility, making it a solid, mid-range foundation set for general metal and wood drilling.

Champion states the Brute Platinum drills three times longer than competitors, which suggests extended tool life under ideal conditions. Its premium high-speed steel is designed to flex where cobalt bits might chip or snap, a potential advantage in hard materials like stainless steel or titanium alloys. The self-centering 135-degree split point helps prevent walking on curved surfaces, and the flatted shanks provide a solid grip in keyless chucks for faster bit changes.

The mechanics length and reduced overall length are engineered for added strength and rigidity when drilling hard metals. This design inherently limits maximum drilling depth compared to longer bit styles. The 29-piece set in its water-resistant index case weighs 2.1 pounds, giving it a dense, substantial feel for a compact organizer.

Its Titanium Nitride coating fights heat and friction, which can extend the cutting edge life up to six times longer than standard high-speed steel. This makes the set a solid choice for anyone regularly drilling metal or hard materials who wants to reduce how often they replace bits. The pro-grade 135-degree split-point tip bites in immediately, so you spend less time chasing a wandering bit and more time making holes. It’s built for users who value longevity and precision in a straightforward, durable package.

Its size range is more focused. With 15 pieces, it covers common tasks but can’t match the breadth of a larger set like the 29-piece IRWIN 3018005. The case, while well-organized and tough, isn’t the most space-efficient on a crowded shelf. For a home workshop tackling frequent metalwork or a contractor who burns through standard bits, the titanium coating’s durability justifies the focused selection. If your projects demand a specialized bit size every other week, however, a more comprehensive kit might save you a separate trip to the store.

A 29-piece set in 1/64″ increments gives you a drill bit for nearly any fractional hole you’ll need in common materials. The heavy-duty HSS with a corrosion-resistant finish is built for shop and job site wear, and the self-centering 135-degree split point bites into metal without walking. This is the set you grab when you need a reliable bit in a common size and don’t want to hunt through a disorganized drawer. It’s built for the tradesman or serious DIYer who drills into steel, wood, and plastic regularly.

This is a set of fractional jobber bits. As noted in expert round-ups, it won’t cover the letter, number, or metric sizes a machinist requires. Compared to a more compact set like the DEWALT DWA1181, the Drill America comes in a larger round case, which organizes well on a bench but takes up more space in a packed tool bag.

Covering sizes from 1/16″ to 1/2″, this 29-piece set handles nearly any common hole size for home repairs and DIY projects. The high-speed steel construction with a black and gold oxide finish offers heat resistance and durability, which helps the bits stay sharp through repeated use. A 135-degree split point tip prevents walking for more precise starts, making it easier to drill cleaner holes in soft metals, wood, and plastic.

These bits are not recommended for hardened steel or stainless steel, so they have a clear limit on tougher metals. Drilling plastic requires lower speeds to prevent melting, a necessary technique for that material. While other sets in the category may offer different case sizes or weights, the Yougfin set provides a wide size range focused on general-purpose tasks for DIYers and homeowners.

The 5% cobalt content in this M35 steel is the key spec for anyone regularly facing hardened steel or stainless. That alloy makes the bits significantly harder and more heat-resistant than standard HSS, so they stay sharp longer when the going gets tough. This set is built for the specific, demanding task of metal fabrication, not as a catch-all for the workshop. Its split-point design provides better automatic centering and prevents walking on hard surfaces, keeping your holes precisely where you mark them.

This set offers focus over flexibility. You get 15 bits, but they’re all the same 1/4-inch diameter. That’s perfect for a production task or prepping for a specific tap size, but you’ll need another set for stepped drilling or varied hole sizes. Other sets in the guide contain more pieces, which often indicates a wider diameter range. But when your project list is dominated by steel, the RCINDUS M35’s specialized composition is the pragmatic choice for getting through it without constant bit changes.

The TiAlN coating’s ability to handle temperatures up to 1472°F is the defining feature here. It directly translates to less heat-related wear, so these bits stay sharper longer when you’re pushing through stainless steel or titanium. This set is for the metalworker who regularly encounters hardened materials and needs a bit that won’t soften or degrade under sustained, high-friction drilling. The M35 cobalt core and the aggressive chip clearance from the triple-flute design support that core heat-resistance claim perfectly.

That advanced geometry does come with a practical limitation. The manufacturer specifies the triple-flute design is recommended for standard depth of cut applications, meaning it might not be the best choice for extremely deep-hole drilling in a single pass. For a more conventional and versatile approach to general metal and wood, the DEWALT DWA1181 set is a reliable benchmark with its self-starting tip. The Crosstar set trades that universal flexibility for focused endurance in the toughest metals.

A 3-flats shank is the standout feature here, giving you a serious grip in the chuck that reduces spin-out on sizes larger than 3/16-inch. That means more power gets to the cutting edge and less gets wasted as frustrating slippage. The self-centering 135-degree tip helps reduce walking, so the bit starts biting quickly. A black and gold coating helps prevent rust and wear, and the bits are made from high-speed steel for use in plastic, wood, and metal.

You trade off a broad selection of sizes for that superior chuck grip. With 14 pieces, you have a solid working range, but a set like the 29-piece IRWIN 3018005 will cover more incremental sizes. The tapered web design is for extreme durability and resisting breakage. Size markings on the drill bit shank allow for identifying sizes quickly during a project.
