The typical cordless drill operates on battery electric power. But in the hands of builder TimWelds, this everyday tool runs on nitromethane, methanol, and oil. Tim took one of Toyan’s working miniature V8 engines and retrofitted it to drive drill bits. The result is the loudest and most satisfying power drill we’ve seen.
Awesome Power Tools
This alligator-jawed power garden tool makes quick work of cutting branches and logs, while minimizing the safety risks of working with a chainsaw. The LP1000 is a 4.5-amp corded version, while the LLP120 is a cordless version that runs on a 20V MAX rechargeable battery. Both can saw through branches up to 4″ in diameter.
This motorized rotary tool is better than scissors, especially when it comes to cutting materials like plastics, leather, carpeting, cardboard, and vinyl up to 1/4″ thick. It features a self-sharpening blade and ensures a clean, smooth cut in straight lines or curves. Aproca makes a custom-fit carrying case as an accessory.
This small but powerful leaf blower has a 20V, 4.0Ah battery pack for longer runtimes than other cordless models. Its turbine fan can push out air at speeds up to 125 mph, and a variable air control nozzle lets you choose between high-volume or high-speed air. Includes a standard Worx Power Share battery and charger.
Medical professionals use a special power saw to cut through casts when it’s time to remove them. While the high-speed saw blade slices effortlessly through a hardened cast, it does nothing to your body if it makes contact with your skin. Steve Mould investigates the physics that allows this ingenious device to work without causing bodily harm.
By moving its battery to an outside dock, this portable rotary is slimmer than other units. It offers variable speed control, with a top speed of 35,000 RPM. Plus, its 20-volt Power Share base station can be used to power a variety of other tools, including a woodburner/soldering iron, an airbrush, a heat gun, and an angle grinder.
While he could have just bought a cheap jigsaw, Hassan Abu-Izmero enjoys a challenge, so he got to building himself a fully-functional jigsaw that’s driven by the rotating action of a power drill. It took a simple yet clever bit of engineering to convert the drill’s circular motion into the saw’s longitudinal motion.
Bosch’s FlexiClick cordless 12V Drill/Driver System is compact yet incredibly versatile, thanks to its modular design. It has two speed settings, a built-in LED light, and comes with a keyless chuck, a locking bit holder, a right angle attachment, and an offset angle attachment.
When Serengy Technology came across a micromotor from a camera, he thought it would be perfect for driving a miniature power tool. He made his mini drill from a hunk of acrylic, which he painstakingly cut and shaped, then outfitted it with the motor, wiring, hearing aid batteries, and a tiny switch.
This compact CNC machine from Samurai Machine Tools changes tools in as little as 2.3 seconds with its pair of rotating tool carousels and quick-change heads. Its spinning head remains stationary while its pedestal moves the part it’s milling. Watch it in action machining a piece of aluminum. Prices for the machine start at £4990, or about $6345 USD.
Has playing on your old foosball table gotten boring? These guys figured out how to breathe fresh life into the game by attaching a bunch of Ryobi cordless power drills to its spinners. It makes it a lot harder to follow the action, though, and there’s a much better chance of the ball flying off the table and into the neighbor’s yard.
It’s possible to make circular saw blades out of paper, wood, or plastic, but the glass saw blade the Waterjet Channel made could be the worst idea yet. Sure, glass is harder than those other materials, but it’s also more fragile, and the flying shards of glass coming off a spinning disc could cause serious injury. But hey, it’s the internet, so here you go.
“What happens when you try to cut a saw blade with a saw blade?” The Hydraulic Press Channel rigged up a pair of angle grinders with circular saw blades, then pushed them into each other while spinning to see how they would hold up. Under no circumstance should you try anything like this at home.
If you’ve ever had to hammer a nail in a tight space, you’ll appreciate Skil’s cordless power hammer. It can drive nails up to 3.5″ long with its percussive action. A magnet holds nails for one-handed driving, and its head adjusts between 0º, 45º, and 90º angles. Includes a 2.0Ah lithium battery and a quick charger. Demo video here.
Angle grinders can be quite dangerous if not used properly – and in the hands of the Beyond the Press channel, they’re far more likely to cause harm. For their series Grinder Discs That Shouldn’t Exist , they wanted to see what would happen if they attached a circular saw blade to an angle grinder. Then they leveled things up 4x.
Using a Dremel rotary tool to power an R/C helicopter seems like a really stupid idea. But Peter Sripol is the guy who built an airplane out of an angle grinder, and a gas-powered NERF blaster, so if anyone can pull it off, it’s him. But there’s much more to engineering a helicopter than just slapping a rotor onto the Dremel.
Maker and tinkerer Peter Sripol noticed a similarity between the reciprocating motion of a Sawzall and the drivetrain of a steam-powered locomotive. Perhaps jealous of William Osman’s power tool races, he got to work rigging up a reciprocating saw to drive a G Scale locomotive. It works surprisingly well.
The Backyard Scientist continues his trend of playing with stupidly dangerous things. After getting his hands on a 2000-watt industrial laser, he put it through its paces to set things on fire, weld metal, clean rusty surfaces, and cut down a tree like a laser chainsaw. At least he had the good sense to wear eye protection.
This cordless rotary tool is an inexpensive addition to any toolkit. It offers five speeds from 5000 to 15000 RPM for sanding, carving, grinding, polishing, and cutting. Its rechargeable 3.7V battery can spin its motor for up to 200 minutes. The 55-piece kit includes tool bits, cutting discs, grinders, polishers, and sanding bands.
Attaching three sets of hedge trimmers to the motor from an angle grinder seems like a recipe for disaster. But that didn’t stop YouTuber Turnah81 from trying the idea. Frustrated by the inability of electric hedge trimmers to cut through larger leaves, he built this nightmarish power tool that makes the most terrifying sound.
Shadow Foam previously showed us how their thick foam could be used to make a tool organizer wall. Now they’ve teamed up with inventor Colin Furze to help outfit his awesome new workshop with an foam wall for storing his massive haul of Milwaukee power tools. We love this idea for getting big tools like saws up off the shelf.
After hearing about a now-defunct competition where players modded power tools into race vehicles, William Osman gathered up some of YouTube’s most popular makers and content creators to put on their own version of the dangerous drag races. Needless to say, don’t attempt to replicate any of this at home.
