Hyper Tough 20V Max Brushless 4.5-inch Cordless Angle Grinder with 4.0Ah Lithium-Ion Battery and Charger

American company. I have several other Hyper Tough tools and therefore have plenty of batteries. Tool is light weight and I like that it does not spin as fast as the corded grinder, different brand. This means the gyroscopic forces are not as great. This is a benefit for more detailed use.

Overall for the money and some really it doesn't stay running keeps. I'll be cutting. And it just shuts off, and I have to shut it up, turn it back on with the power switch and start cutting the chefs back off again. I would never, ever buy this product again

This angle grinder works exactly as expected. The power is robust and sustained. I used this grinder for cutting (with a seperately bought cutting disk) 3/8" allthread and 1/8" welding steel which took about 20 minutes, and then later to dress a cast steel anvil's edges which took about 15 minutes, and with full charges to start both jobs the 4.0Ah battery was more than sufficient for each task. With that performance, I can't see any future job being outside the capability of this tool.

Great piece of equipment. Finally able to sharpen brush cutter blades while attached to tractor. Battery interchanges with other hyper-tough tools. Get it.

This grinder is really great for being cordless. Comes with a 4Ah battery. I use it for cutting steel and rebar, and it's powerful enough to cut through it like butter. 5/5

i literally charged the battery cut it and with in 3 mins it burnt up smelt like the gears are cooked

Works great easy to use if you are purchasing for use around the shop it is perfect for that. I enjoy using the tool.

Works great has plenty of power for grinding. Would recommend for small jobs not needing a lot of electric power

this product is built with great material lightweight easy to handle and the battery is long lasting

so far I like the angle grinder it works pretty well I just wish the battery expectancy of life would last longer
