Powerful and convenient but don’t love the head design. [This review was collected as part of a promotion.] This tool is a great size, much easier to use for fine grinding tasks than a dremel—much easier to get into hard to reach places, good one handed operation. The power is also good. Included bits are nice and versatile. The one thing I didn’t really like was the head design. Changing bits is not all that easy and it’s possible for the bits to back out while in operation and become less secure and even fall out while the motor is on, which was my biggest issue with the tool

A reliable and effective tool that is perfect for both DIY enthusiasts and more experienced users. [This review was collected as part of a promotion.] I recently tried out the Hyper Tough 12-volt 1/4 inch cordless die grinder, and I must say, it exceeded my expectations. The operation is straightforward, making it user-friendly even for those who might not have much experience with power tools. One feature that stood out to me is the safety lock on the trigger, which provides added peace of mind during use.
I used the die grinder for various tasks, and it performed consistently well. The textured grip ensures better handling and control, which is crucial for precision work. Whether I was sanding or grinding, the tool made the process smooth and efficient.

Good tool. [This review was collected as part of a promotion.] Started using this grinder right away. It is nice and light and easy to monster. The different speed settings are great for different applications. Seems to be built well and runs pretty quietly. Not to fond of the way you charge the battery.

Versatile and great for small jobs. [This review was collected as part of a promotion.] The Hyper Tough 12V Brushless Die Grinder is well made and Versatile. It has a safety lock on the trigger, four mode speed control, and comes with many helpful accessories. The wire wheel brush made grinding rust off tools, easy and smooth.

Cheap. [This review was collected as part of a promotion.] The Hyper Tough Brushless Die Grinder lacks the necessary power when you are looking to get the job done. It does clean up metal when you need to have a fresh weld, but automatically shuts off if the motor can’t take it. It is small and portable, so doing small tasks is an easy feat. It’s quiet enough to not wake neighbors if you’re trying to get the rust stains off of your 86 Chevy that your dad gave you because he lost his license while drinking and driving. It took the nasty stains off of my wife’s cast iron pan. Not great, but worth the money.

Tool only. Tool only option saves money and unwanted extras.

Perfect! Exactly the grinder my husband wanted for Christmas and considerably cheaper than Amazon. Quick delivery too!

It works, but not for long. It’s very handy the way the battery charge is an ideal. The battery life is horrible. But compared to $219 for the Milwaukee one this one will do the trick for today and tomorrow, but that’s about it then I’m gonna bite the bullet and just buy the good one from Milwaukee.

Simply awesome. These things for the money are the best bang for the buck you cannot go wrong.

Very Surprised!!! I needed a cutoff tool for a job in Denver that I was flying to and did not want to buy the $200 equivalent in the Red Brand. I also bought a 6Ah battery and a fast charger to make sure I had enough juice. This tool performed flawlessly and cut through probably 27 feet of Unistrut, a bunch of chain and all-thread. The brushless line of Hyper-Tough 12V is well worth the money and takes the abuse. I highly suggest trying the tools.

Quality. Best die grinder I’ve ever owned

Fantastic die grinder at a great price. For the price, this compact die grinder can’t be beat. The closest in size comparison I would say is the Milwaukee, but it will set you back $250-300. You won’t regret picking this one up to add to your tool cart. USB charging is great and all of the attachments are inexpensive.
