I use this grinder when installing door hardware. Used for cutting steel and alum. parts. Works great. It spins slower then my electric units but seems to make the blades last longer anyway. well balanced using the 5 amp hour battery.

How long can be used before recharge in production no stop ?
Edwin on Apr 19, 2016
BEST ANSWER: That is a very difficult question to answer, runtime depends on many variables. Without knowing whats being done with the grinder, continous runtime could be anywhere from 30 minutes to a couple hours with the 4Ah battery. Keep in mind, charge time is relatively short, with a couple of batteries you can get alot accomplished with little
downtime.
The description states "Tool-free accessory changes," but a reviewer said that he needed a tool to remove the flange nut. The downloadable manual also states that a spanner wrench is required to tighten and loosen the flange nut. Also, if accessories can be changed without a tool/wrench, why is one included? Can wheels/accessories be installed and removed without a tool or not?
A shopper on Nov 25, 2017
BEST ANSWER: In almost all cases, you can swap blades without a tool. If the blade is the face, on the back of the head is a lever which unclamps the spindle. It is not enough to flip this lever up; you must flip it all the way forward. When you do, the spindle/arbor tension is released and you can unscrew the spindle-cap/arbor-nut with your fingers. If you don't understand how this works, you will probably overtighten the cap/nut and then need a wrench to get it off again.

So, wheels/accessories CAN be installed without a tool, if you don't go out of your way to make it more difficult than necessary.
Can you interchange the types of Milwaukee batteries with chargers and tools?

BEST ANSWER: All Milwaukee 18 volt lithium ion tools and batteries are compatible,so yes everything is interchangeable.
