    • Manage your expectations
I am an industrial mechanic (think oil rigs, oil refineries, power plants, etc), it is a fast paced, heavy duty environment. The idea of a cordless die grinder has always been alluring to me given the sometimes remote areas I work in. This is an excellent product. The RPMs (0 - 21,000) are governable depending on how much you squeeze the trigger, which is nice for carbide burr bits, and the tool is light weight and easy to manipulate. I saw in previous reviews that people are having difficulty inserting quarter inch accessories into the collet. This is typical with new die grinders and gets easier over time. Unscrewing the collet just a little more will allow the bit to be inserted. I also saw that some people were having trouble removing a bit, that is the point of what is quite frankly a dangerous tool. Smacking the collet with the provided wrench after loosening it, releases the bit. This is true for every die grinder. All this said. This is not a heavy duty tool, however, DIYers or hobbyists would love it. If you're imagining a pneumatic die grinder that you've used in the past, you will be disappointed. Under heavy duty loads (cutting through greater than 1/16 inch metal with a cut off wheel, pressing firmly into a work piece with a carbide burr) the tool does bog down and sometimes stall. This tool is for light applications, if you're OK with that, this tool will serve you well and you'll enjoy using it. ... show more

    • you will not believe me!
You wil not BELIEVE, what this did for me. I'm a perfessional yet still intermediate mechanic of two years. This tool i purchased to clean wheel hubs and it had a wire wheel on it when i went to work today. I just bought this straight grinder after buying a milwaukee angle die grinder from cornwell last week. i ordered a 1/8 burr on accident then ordered a 1/4 carbide burr set for this grinder from amazon too. i go to work today and turns out i have to drill out a broken exhaust bolt on a 2011-ish honda accord. i cant fit my milwaukee drill in their or my 90 degree air drill. i remembered my old blue point air drill and i started drilling and learning a lesson on pilot holes and sizing up to cut rather than just picking a bit and going with that.. anyways i was using hypersteps. it was slow drilling with the small bit bits, sizing up ut then i grab with die straight die grinder, put in a pointy carbid bit and opened up the hole i was slowing frilling into.. the small hyper step sizes dont have the step parts.. so after i used this die grinder and a carbide burr to open and even center the hole, i moved up about three to four drill sizes into the drill sizes that have hyper steps and they absolutely DESTROYED this rusted out fastener and cut all the way through. i then chose the die grinder and the carbide burr option again at max 21,000 rpm to open up the hole and the tool THROWS the old bolt OUT revealing threads!! the threads only need a chaser to work out and the exhaust will be repaired. AMAZING!!! YOU HAVE NO IDEA, just how cool that really is. ... show more

    • Excellent tool, brand name price.
Excellent quality die grinder. Perfect for detailed work in small spaces. But you pay the brand name price.

    • Important info/step to use.
Haven’t used it yet, but tried to test it and couldn’t get a 1/4” mandrel to fit. I fought with it awhile and was getting frustrated and didn’t look at the instructions. I went to YouTube and found a review video that explained my issue. If the cylinder clamp and nut are two separate pieces (as mine were) it will not work. Remove the cylinder clamp and push it up into the nut until it clicks and stays. Once I did this, my 1/4” mandrel fit like it should. Having three separate dedicated/set rpm settings should come in handy compared to my Ingersol Rand air powered units. ... show more

    • Great for grinding engine parts
Great for modifying cast aluminum supercharger housing. When it came, part of the collet was stuck and the Milwaukee box seemed damaged but the tool itself worked fine after I pulled the collet out with pliers and applied some grease to it.
