If you love tackling home projects, you've probably bent, dulled, or tossed a drill bit that stopped biting. Sharpening drill bits can save you money, improve accuracy, and keep your drills running cooler and longer. Think of a sharp bit like a sharp knife — it makes every cut cleaner and safer. In this guide I’ll walk you through the best types of drill bit sharpeners, which U.S. stores sell them, and how to pick the right accessories for your toolbox.
Sharpening a drill bit restores cutting edges so holes are cleaner and drilling takes less force. Instead of buying replacement bits by the box, you can extend the life of quality bits — especially cobalt, HSS, and carbide-tipped designs. For hobbyists and pros alike, this means fewer trips to the store and more time actually building. Plus, a sharp bit reduces heat buildup, which translates to fewer broken bits and less damage to materials.
Drill bit sharpeners come in a few flavors: bench grinders with jigs, dedicated electric sharpeners, and handheld manual systems. Bench grinders with a drill jig are cost-effective if you already own a bench grinder. Electric sharpeners automate angles and can handle a wide range of sizes, while manual sharpeners are compact and work well for touch-ups on smaller bits like 1/16" to 1/2".
These setups use a grinding wheel and a jig to maintain consistent angles. If you have workshop space and a bench grinder, this gives you flexibility to sharpen many bit types. Expect to learn a bit of technique — it’s like learning to ride a bike, but once you get it, you won't forget.
These plug-in units handle a wide range of bit diameters and often include adjustable angle settings. They’re fast and user-friendly — perfect if you want results in minutes rather than practice hours. They’re a great match for contractors who need repeatable results without fuss.
Portable and affordable, handheld sharpeners are ideal for occasional sharpening. They’re the Swiss Army knives of the drill-accessory world — not as powerful as an electric unit, but handy when you’re on a ladder or out in the yard and don’t want to haul a grinder.
When shopping for sharpeners and related drill accessories in the U.S., look for retailers that offer a wide selection, good return policies, and helpful customer reviews. Here are reliable options that stock sharpeners, jigs, and quality drill bits.
The Home Depot is a go-to for many DIYers. You’ll find electric sharpeners, drill jigs, and a big selection of drill bits from Bosch, DeWalt, and Irwin. They often carry entry-level and professional sharpeners and provide local pickup if you want to inspect the unit before taking it home.
Lowe’s mirrors many of Home Depot’s offerings and sometimes has different tool combo deals. They stock bench grinders, sharpening jigs, and tool brands like Metabo HPT and Milwaukee. If you prefer hands-on shopping, Lowe’s store staff can usually point you to compatible accessories based on the bits you own.
Harbor Freight is the value-oriented choice. You’ll find budget bench grinders, sharpening attachments, and occasional in-house brand sharpeners. While some units aren’t built for daily contractor use, they’re perfect for hobbyists or occasional projects and are easy on the wallet.
Ace Hardware stores are great for local support and quick pickups. They usually stock quality bits and small sharpeners suited to homeowners. If you want personalized help selecting a sharpener for a specific bit size like 1/8" or 1/4", Ace employees often provide hands-on advice.
Northern Tool is a good option for more heavy-duty or specialty sharpeners. If you need industrial-grade electric sharpeners or jigs that handle large-diameter bits up to 1/2" or more, they’re worth checking. Their tools are aimed at tradespeople who demand consistent durability.
Amazon and Walmart offer huge selections and user reviews that can help you compare models quickly. Amazon’s marketplace features brands like Drill Doctor and Dremel, while Walmart often lists affordable manual sharpeners and combo kits. When buying online, be sure to read reviews for real-world feedback on longevity and angle accuracy.
Prices vary widely depending on build quality and features. Manual sharpeners can be under $20, entry-level electric models often range from $50 to $150, and heavy-duty professional units can cost several hundred dollars. If budget is tight, start with a manual unit or a bench grinder jig — both are cost-effective ways to begin sharpening without breaking the bank.
Keep an eye out for holiday sales, tool events, and store coupons. The Home Depot and Lowe’s frequently have seasonal discounts, and Harbor Freight offers stacked coupons that can cut costs dramatically — sometimes bringing a $50 grinder down to a fraction of the price. Signing up for newsletters from these stores can reveal hidden deals.
Used sharpeners or bench grinders can be found on marketplace sites and local classifieds. Used tools can be bargains, but inspect the grinding wheel for cracks and check for wobble. A well-cared-for used unit can serve you for years, but avoid anything that looks excessively worn or damaged.
Brand reputation matters when you want predictable angles and durable construction. Drill Doctor is a well-known brand for compact electric sharpeners. Dremel offers multi-tool attachments useful for touch-ups. For grinders and jigs, Irwin and Drill Hog make solid jigs, while established power tool brands like DeWalt, Bosch, and Makita offer reliable bits that are worth sharpening.
High-speed steel (HSS) and cobalt bits sharpen very well on grinders and electric sharpeners. Carbide-tipped bits are harder and often require diamond abrasives or special equipment. If most of your bits are carbide, look for a sharpener specified for carbide use or consider replacing cheap carbide bits instead of investing in expensive sharpening gear.
Different materials require different point angles. For example, wood typically works well with a 118-degree point, while harder metals often benefit from a 135-degree split point to reduce walking and improve cutting. Many electric sharpeners let you set the angle to match the material you drill most often.
A few accessories make a big difference: drill bit sets (organized by diameter), magnetic bit holders, depth stops, and countersinks. Protective gear like safety glasses and gloves is essential when using grinders. Also consider a drill index to keep bits organized by size — that cutdown on drilling the wrong hole by mistake.
Magnetic bit holders speed up switching driver bits during projects. Quick-change chucks let you swap bits in seconds, which pairs well with sharpened bits because you’ll likely be changing between sizes more often. These little conveniences save time and keep momentum on the job.
Organized storage extends bit life. A good case protects the cutting edges from knocks, and labels help you grab the correct size — from tiny 1/16" bits to larger 1/2" bits — without guesswork. Treat your bits like fine tools; a small investment in storage pays big dividends.
Ask yourself: how often do I drill, what materials do I work with, and how precise do I need cuts to be? If you’re a weekend warrior drilling wood and drywall, a manual sharpener or budget electric model will likely do the trick. If you run a small shop or regularly drill metal, invest in a robust electric sharpener or a grinder with a precision jig.
Look for compatibility with bit diameters you own, adjustable angle settings, ease of use, and warranty coverage. If the sharpener handles 1/16" up to 1/2" bits, it covers most home and professional tasks. Also factor in the availability of replacement grinding wheels or diamond stones — maintenance matters.
Noise, dust, and workshop space matter. Bench grinders produce sparks and dust, so consider a dust collection system if you sharpen indoors. Electric sharpeners are less messy but can still kick up fine particles — safety glasses are non-negotiable.
Start by cleaning the bit and checking for major damage. Set the angle according to material — 118 degrees for general-purpose, 135 for harder metals — and take light passes until the cutting lips are even. Keep the bit cool by dipping it in water periodically; overheating can ruin temper and reduce hardness.
1) Clamp or hold the bit securely. 2) Match the angle on your sharpener/jig. 3) Make light, even passes. 4) Check symmetry frequently. 5) Cool the bit if it heats above a warm touch. Practice on a cheap bit before trying your favorite pricey cobalt bits.
Replace grinding wheels on a schedule and keep the sharpener clean from metal dust. Inspect power cords and bearings for wear. Always wear eye protection and avoid loose clothing around spinning wheels. A steady hand and respect for the tool reduce accidents and extend the life of both the sharpener and your bits.
If a bit has deep chipping on the flute, a severely rounded tip, or a large notch, sharpening may not restore it. For safety and consistent results, retire bits with major structural damage and recycle them if possible. Sometimes buying a new, precision-ground bit is more economical than spending hours on imperfect restoration.
Drill bit sharpeners are smart investments for anyone who uses drills regularly. Whether you choose a handheld sharpener, an electric unit, or a bench grinder with a jig, the right tool keeps your bits cutting cleanly and extends their life. Big-box stores like The Home Depot and Lowe’s, value outlets like Harbor Freight, specialty sellers like Northern Tool, and online marketplaces such as Amazon and Walmart all offer options for every budget. Pair your sharpener with proper accessories and storage, and you’ll be surprised how much smoother your projects go — like turning a rocky trail into a paved road.
