If you’ve ever wandered a trade show, a makerspace, or a small custom metal shop, you’ve probably spotted one of our metal lathes humming softly in a corner, spinning chunks of aluminum, brass, or steel at just the right speed to turn rough stock into precise, usable parts. Over the years, the most common question I get from first-time buyers is not about large industrial projects or custom machinery parts—it’s this: “Can I actually use a metal lathe to make something as small, simple, and, well, casual as keychains?” Metal Lathe
The short answer is: Absolutely. But the longer, more interesting answer is that making keychains on a metal lathe isn’t just a novelty hobby trick—it’s a practical, cost-effective way for small businesses, side hustlers, and even educational programs to create high-quality, long-lasting products that stand out from the mass-produced plastic keychains at big box stores. Let’s break this down, from why metal lathes work so well for keychain production, to the steps to pull it off, to why our lathes are built just right for this kind of work.
First, let’s talk about why metal is a better base for custom keychains than plastic, resin, or even wood. Plastic keychains melt, crack, and fade after a few months of being tossed in a bag, left in a hot car, or banged around with a set of keys. Resin ones chip easily if they’re knocked against a hard surface, and wood can splinter if not sealed properly. Metal keychains, though? They’re durable. An aluminum or brass keychain will outlast multiple sets of keys, hold engraving or embossing that won’t wear off, and even develop a nice patina over time if that’s the look you’re going for.
Now, you might be thinking: “A lathe is for making things like engine parts or furniture spindles—how do you make a keychain on something that’s designed for precision, not small trinkets?” The truth is, metal lathes are incredibly versatile, and modern benchtop models (the kind most small shops and hobbyists use) are built to handle tiny, detailed work just as well as large industrial jobs. Our lathes, for example, have adjustable spindle speeds that range from 50 RPM up to 2,500 RPM, which means you can slow things way down for cutting thick metal or speed up just enough for finishing small, delicate features like keychain loops or custom shapes.
Let’s walk through the actual process of making a keychain on a metal lathe, so you can see how straightforward it is. First, you start with a blank keychain “slug”—a small piece of metal, usually aluminum or brass, cut to a standard size (maybe 1 inch wide, 2 inches tall, and 1/8 of an inch thick) depending on the keychain design. You mount this blank onto the lathe’s chuck, which is the part that spins the workpiece. For small blanks, a 3-jaw self-centering chuck works perfectly; it grips the metal evenly so it doesn’t slip while you’re cutting.
Next, you shape the keychain. If you want a simple, classic round keychain, you can use a turning tool to cut the edges of the blank into a smooth circle. If you want something more custom—like a shape of a favorite animal, a logo, or a monogram—you can use a combination of turning, facing, and even knurling tools to create details. Knurling, for example, is a process where you roll a pattern into the metal to create texture, which is perfect for making a keychain’s finger loop easier to grip, or adding a decorative pattern along the edges.
Once the shape is cut, you drill the keyhole—the loop that will hold the key ring. On a metal lathe, you can mount a drill bit into the tailstock (the movable part on the opposite end of the chuck) and drill a precise, centered hole for the loop. This is a big plus over drilling by hand, because the hole will be perfectly straight and aligned, so the keychain doesn’t wobble when you attach the ring. After drilling, you can deburr the edges with a sanding stick or a file to get rid of any sharp metal bits, then polish the surface for a smooth finish.
The final step is adding custom details: engraving, painting, or even adding text. If you’re using our lathes, many models can work with small engraving tools, or you can send the cut keychain blanks to a local engraver, but some makers even do light engraving right on the lathe. For small businesses, this is where you can add that personal touch that makes your keychains sell—engraving a name, a wedding date, a team logo, or a custom phrase. Unlike plastic keychains, the engraving on a metal keychain won’t fade or rub off over time, which means your customers will keep your product for years, and word-of-mouth will spread fast.
Now, you might be wondering about scale. Can a metal lathe actually produce keychains in enough quantity to turn a profit? Let’s do the math. A small benchtop lathe (like many of the models we supply) can make one custom keychain in about 5 to 10 minutes, once you’re familiar with the process. If you work 4 hours a day, that’s roughly 24 to 48 keychains per day—more than enough for a side hustle selling at farmers markets, Etsy, or local craft fairs. If you need to produce more, a slightly larger semi-automatic lathe can crank out 100 or more keychains per day, which is enough for small local orders or online bulk sales.
The biggest advantage of using a metal lathe for keychains, though, is customization. Mass-produced keychains are limited to the designs big manufacturers can make with injection molding, which requires expensive molds that cost thousands of dollars to create. With a metal lathe, you can make a custom keychain for one person, or 1,000 identical keychains for a wedding party or a company swag order, all without paying for costly molds. If a customer wants a keychain shaped like their dog, their favorite book, or their business logo, you can make it on a lathe in a matter of hours, not weeks.
I’ve seen this first-hand with some of our customers. Last year, a customer named Jake, who runs a small woodworking shop, bought a benchtop lathe from us and started making custom keychains as a side project. He told me that within six months, his keychain side hustle was making more money than his woodworking projects for individual clients, because people were willing to pay $15 to $25 for a custom metal keychain, compared to the $5 he spent on materials to make it. Another customer, a local high school, bought a lathe for their engineering class, and now students make keychains for the school’s sports teams as fundraising projects.
But to get good results, you need the right lathe for the job. Not all metal lathes are created equal, and a heavy-duty industrial lathe designed for making car parts is overkill for small keychain production. That’s why we design our lathes to be accessible for both hobbyists and small businesses: they’re compact enough to fit in a small garage or a 10×10 foot workshop, they’re easy to operate even for people who are new to metalworking, and they have the precision to make small, detailed parts like keychains without breaking the bank.
One common mistake new makers make when using a metal lathe for keychains is choosing the wrong material. Aluminum is the most popular choice for keychains because it’s lightweight, easy to cut, and affordable. Brass is a step up, with a nice gold tone that looks more premium, and it’s still easy to work with. Steel is more durable but heavier, so it’s better for keychains that will be used for heavy purposes, like tool keychains for construction workers. We always recommend starting with aluminum for beginners, because it’s less likely to cause tool wear, and it’s cheaper to experiment with.
Safety is another thing to keep in mind, but it’s no different than using any other power tool. When working with a metal lathe, you need to wear safety glasses, tie back long hair, remove any loose jewelry, and keep your tools and work area clean. Our lathes come with safety guards and detailed operating manuals that walk you through every step, from setting up the lathe for keychain production to finishing the part. We also offer free training calls for all our customers, so if you’re new to lathe work, we can help you get started.
So, to circle back to the original question: Can a metal lathe be used for making keychains? The answer is a resounding yes. It’s not only possible—it’s a smart, profitable way to start a side hustle, add a custom product to your small business, or teach hands-on metalworking skills to students. Metal keychains are durable, customizable, and in high demand, and a good metal lathe makes the process fast, easy, and cost-effective.
