What to Look For in a Farm-Tough Drill Bit Set
The material of the bit tells you what it’s made for. Basic High-Speed Steel (HSS) is fine for wood, but for the mix of materials on a farm, you want more. A black oxide coating helps resist rust and heat, while a titanium coating adds serious durability for drilling into mild steel and other metals. For the really tough jobs, like drilling through a tractor frame or hardened steel, nothing beats a cobalt bit.
Pay close attention to the tip. A standard 118-degree point will do the job, but it has a tendency to "walk" or wander when you start a hole. Look for a 135-degree split point tip. This design bites into the material immediately, preventing walking and eliminating the need to use a center punch every time.
Finally, don’t underestimate the case. A flimsy plastic case that shatters on the first drop, spilling two dozen tiny bits into the dirt, is a special kind of frustration. A durable, well-organized case that clearly marks the bit sizes saves you time and keeps your investment protected. You need to be able to grab the right bit quickly, not spend ten minutes hunting for it.
DeWalt DW1354 Titanium: The All-Around Workhorse
If you could only have one drill bit set in your workshop, this would be a top contender. The DeWalt titanium set is the definition of a reliable workhorse. It strikes the perfect balance between cost, durability, and performance for the vast majority of farm tasks.
The titanium nitride coating helps these bits last significantly longer than standard HSS bits, especially when you’re drilling through the angle iron on a gate or the steel frame of a workbench. They handle wood and plastics without breaking a sweat. The pilot point tip is DeWalt’s version of a split point, and it does a fantastic job of starting holes cleanly without wandering, which is a huge help when you’re in an awkward position under a piece of equipment.
This set comes in a classic tough case that can handle being tossed in the back of a truck. For general repairs, from fixing fence posts to mounting hardware on a barn door, the DeWalt set has the right combination of sizes and strength to get it done without fuss. It’s the set you’ll reach for 90% of the time.
Milwaukee Red Helix Cobalt for Tough Metal Drilling
Sometimes, you hit a piece of metal that just laughs at a regular drill bit. This is where you stop what you’re doing and grab the cobalt bits. The Milwaukee Red Helix Cobalt set is specifically designed for drilling into hard, abrasive metals like stainless steel, cast iron, and hardened bolts.
Unlike titanium bits which are just coated, cobalt bits have the cobalt alloy mixed right into the steel. This means they can withstand extreme heat without losing their sharp edge. When you’re drilling thick steel, heat is the enemy, and these bits are built to win that fight. The "Red Helix" design is more than just marketing; the aggressive shape helps pull metal chips out of the hole efficiently, which keeps the bit cooler and drilling faster.
Let’s be clear: this is a specialized tool. Using these on wood is like using a sledgehammer to crack a nut—total overkill and a waste of a premium bit. But when you need to drill out a broken exhaust manifold bolt or modify a heavy-duty trailer hitch, having a cobalt set is the difference between a thirty-minute job and an all-day nightmare.
Irwin Hanson Set: A Classic for Wood and Steel
There’s a reason you see well-worn Irwin bit indexes in old farm shops. They’re a classic for a reason: they just work. The Irwin Hanson sets are no-nonsense tools that have been trusted for generations to handle a mix of wood and common steel applications without complaint.
These bits typically feature a 135-degree split point, so they start clean and drill true. They are ground from HSS and perform reliably for tasks like drilling pilot holes in hardwood posts, running bolts through a wagon bed, or general metal fabrication with mild steel. They may not have the high-tech coatings of newer sets, but they are manufactured to solid standards.
Think of the Irwin set as the trusty old pickup truck of drill bits. It’s not the fastest or the fanciest, but you know it will start every time and get you where you need to go. It’s a great choice for a primary set that can handle a wide variety of materials without breaking the bank.
Norseman Magnum Super Premium for Lasting Quality
When you’re ready to invest in a set of bits that you can pass down, you look at Norseman. These are premium, American-made bits designed for machinists and serious fabricators, and that quality is exactly what you want when a critical repair is on the line. They cost more upfront, but their longevity makes them a sound investment.
Norseman bits are made from a special "Moly" tool steel and heat-treated for maximum hardness, meaning they hold an edge for an incredibly long time. A key feature is the three flats ground onto the shank of the larger bits. This simple design element prevents the bit from slipping in the drill’s chuck under high torque—a common and dangerous problem when drilling heavy steel.
These bits are made to be resharpened over and over again. While other bits are disposable, a Norseman set is a long-term tool. For someone who does a lot of metalwork and values tools that are built to last, this is the set to own.
Ryobi Black Oxide Set: Best Value for Many Sizes
Not every job requires a premium, expensive drill bit. Sometimes, you just need a specific size for a one-off task, and having a wide selection is more important than ultimate durability. This is where the Ryobi Black Oxide sets shine, offering an incredible number of bits for a very low price.
The black oxide coating provides a basic level of corrosion and heat resistance, making them a step up from uncoated bits. They work perfectly well for wood, PVC, and occasional drilling in thin, soft metal. Having a full index of 20+ bits means you’ll almost always have the exact size you need for a pilot hole or clearance hole.
You have to be realistic about their limitations. These are not the bits you want to use to drill through a half-inch steel plate; they will dull quickly under that kind of abuse. But for the price, you can’t beat the value of having a comprehensive set on hand for all the light-duty tasks that pop up around the farm every single day.
Neiko Step Drill Bits for Sheet Metal and Tanks
A standard twist drill bit is the wrong tool for drilling holes in thin material. It will catch, tear the metal, and create a jagged, ugly hole. For sheet metal, electrical boxes, or plastic water tanks, a step drill bit is an absolute game-changer.
A single step bit can drill a dozen different hole sizes. As you push the cone-shaped bit through the material, each "step" drills the hole to a larger diameter, creating a perfectly round, clean hole every time. It even deburrs the edge as it goes. This is the only way to get a professional-looking hole for installing a bulkhead fitting in a water tank or running wiring through a metal panel.
You don’t need a whole set of them, but having at least one or two step bits in your toolbox is non-negotiable. They solve a specific but common problem with an elegance and efficiency that no twist bit can match. It turns a frustrating task into a simple, two-minute job.
Keeping Your Drill Bits Sharp and Ready for Work
The best drill bit in the world is useless if it’s dull. A dull bit doesn’t cut; it scrapes and pushes. This generates a massive amount of heat, which ruins the bit’s temper, makes the job take forever, and is downright dangerous.
The two most important rules are to use the right speed and to use lubrication. Slower speeds are better for harder materials, and a drop of cutting fluid, 3-in-1 oil, or even motor oil when drilling metal will dramatically extend the life of your bit. The oil cools the bit and helps flush away metal chips.
Eventually, every bit will get dull. You can learn to sharpen them by hand on a bench grinder—it’s a skill worth learning. Alternatively, an affordable sharpener like a Drill Doctor can pay for itself quickly by reviving your old bits instead of forcing you to buy new ones. A sharp bit is a safe bit, and it makes the work go faster.
Ultimately, the best drill bit set is the one that fits the work you do most often. A solid all-around titanium set will handle most repairs, but supplementing it with a few cobalt bits for tough metal and a step bit for thin materials will prepare you for virtually any repair the farm can throw at you. Don’t cheap out on your bits; they are the sharp end of your most versatile tool.
