Mobile equipment technician, I use a die grinder almost a daily. Often I can't get an air source anywhere near the job. This and other M18 tools have essentially replaced my air tools.

Super sweet tool!
I needed a grinder to remover any sharp edges made from my router while installing radiant tubing for heated flooring. It gives you the ability to work in tight spaces and grind at multiple angles. This is all I have used it for as of now, but Can’t wait to take advantage of this tools versatility.

Always wanted a die grinder battery powered of course. The brushless design is what sold me as it's the latest technology.

Can I use this tool with a cut-off wheel? If so, can I easily find cutting wheels to fit?
Jerry on Jun 18, 2017
BEST ANSWER: This is a die grinder not a cut off tool in order to use as a cutoff tool you would have to buy Arbor adapter
Is it a variable speed ?
A shopper on Oct 23, 2018
BEST ANSWER: Model 2784-20 is not a variable speed unit.
Is there a gard for a cutting wheel ?
A shopper on Sep 8, 2018
BEST ANSWER: No guard, you maybe better off with an angle grinder.
Can this tool also be used to Tap steel with a “Tap”(whichever thread count needed)?
A shopper on Jul 18, 2018
BEST ANSWER: No - it’s rpms are too high. If it’s thinner metal, it would be better to use a Milwaukee drill with a self drilling tap (combo tap).
What RPM does it run at ?
A shopper on Jan 8, 2018
BEST ANSWER: 20,000 - it really zings, and has plenty of power!
