About TEENO
TEENO started in 2020 with a cordless drill and an electric screwdriver. The idea was simple: tools that do real work around a house, a garage and a small shop, at a price you do not have to think twice about. The range grew from there, one tool at a time, each one first tried on our own bench.

Today the TEENO lineup counts ten tools, from the 3″ Mini Angle Grinder to a 20 V combo kit with nine heads. Most of them run on batteries, and each cordless kit leaves the box ready to work: batteries, a charger and the discs, bits or blades the job needs.
Our grinders are where most people meet TEENO. The 3″ Mini Angle Grinder spins a 3 in disc at 19,500 RPM, and you can run it with one hand. It is the tool you grab for the bolt that rusted on, the threaded rod that runs long, the tile edge that needs trimming. When the job gets bigger, the 5″ Brushless Angle Grinder takes standard 4-1/2 and 5 in discs and gives you three speeds, from slow polishing to 8,500 RPM for cutting.
For wood, the 1.25 HP Palm Router is the one we hand to a new woodworker. It is corded, so you will not run out of battery halfway along a tabletop edge, and you get 15 carbide bits to start with. The 20V Oscillating Tool picks up the jobs a router cannot reach: trimming a door casing for new flooring, cutting a square hole in drywall, sanding into a corner.
The 20V Combo Kit is for the person setting up a first tool shelf. One brushless handle drives a drill, an impact wrench, saws and a sander, and everything packs into one hard case. If you already own a battery platform from another brand you like, a kit like this will not join it, so count that before you buy.
At TEENO we are plain about what each tool is for. The 3″ Mini Angle Grinder is not a replacement for a full-size grinder on heavy welds. The 3″ Mini Circular Saw stops at 1/2 in, which is great for drywall and wrong for 2x4s. The 1.25 HP Palm Router takes 1/4 in and 6 mm bits, not 1/2 in. If a tool does not suit your job, another TEENO tool probably does.
A few TEENO products live outside the workshop. The Electric Scissors break down shipping boxes and cut fabric up to 1/4 in. The Hydraulic Crimping Tool presses copper fittings for 1/2, 3/4 and 1 in pipe. And yes, there is a Portable Charcoal Grill, because the people who use our tools also cook out on the weekend.
A word on batteries. Our mini grinders run on 16.8 V or 21 V packs, while the multi-tool and the combo kits use 20 V packs, and every cordless kit includes the charger that fits. Several kits come with two packs, so one charges while you work. Keep a spare in the case between jobs, and you will rarely wait on a charger halfway through a cut.
TEENO tools are sold through our retail partner, so checkout, shipping and returns happen there. The TEENO range starts at $14.99 for the electric scissors and tops out at $197.98 for the 9-in-1 kit. Pick a tool, check the speed, the disc size and the batteries in the box, and read what other buyers say, the three-star reviews too.

Buyer reviews
Five stars, four stars and the odd three: how TEENO tools hold up in real garages.
Perfect for small projects
This is a brilliant small grinder! The batteries last a while and I love that it comes with two of them. It also comes with lots of different blade options and has made my small handyman project super easy to do! I finished my chicken run metal roof using this grinder and it worked perfectly. I highly recommend!

Solid Little Tool for the Price
Bought this to get through a few odd jobs around the house and it has handled everything I have thrown at it so far. Setup was quick, the blade change is tool free which I did not expect at this price, and it came with enough attachments that I have not needed to buy anything extra yet. Battery life is fine for short bursts of cutting and sanding. Packaging was tight and everything showed up undamaged. No complaints so far.

This is a nice set for the$$$$ it seems to be the same quality as my more expensive yellow set. Has good power. Only setback there is only 1 battery.

Works great for my needs! No regrets
Nice feel in your hands, we'll built, I make golf clubs and use this for cutting shafts to length. Works great and I like the vacuum attachment to collect the nasty graphite dust.

Battery life
I really liked this cordless grinder because it has good power, it feels comfortable to handle it and is very practical for performing different cutting, grinding and polishing jobs. I think it's excellent that it includes two batteries because that way you can continue working while the other battery is charging. It also comes with several discs, charger, auxiliary handle, protector and a sturdy case to store and transport everything in an organized way. The design looks robust and the materials seem to be of good quality. Another advantage is that, being wireless, it allows you to work with more freedom, the package comes quite complete and is very convenient for work at home, in the workshop or for metal projects.
