DeWalt 4.5" angle grinder--- too hot to touch?

Just a simple question. Does the 90 aluminum housing on the end of your DeWalt grinder get way too hot to touch? As in, "use it for a steady 5-10 minutes, and it will burn your hand if you touch it for more than a second" hot?

The temp of the handle is fine, but sometimes I want to get a little more leverage holding the grinder with both hands without blocking the airflow to the motor.

Wondering if mine needs to be serviced, or if this is just the nature of the beast. Didn't seem to get THAT hot a couple years ago when it was new.

Yeah, even the plastic body on mine gets really hot after 5-10 min. Like to the point it's uncomfortable even wearing gloves.

This is the fix to running hot on the dewalt grinders. Its rather easy to pop the gear box cover off. I had to replace my brushes and greased the gear box while doing that.

Thanks guys! Answered my question.

Looks like I'll tear it down and pack everything with some new high-temp disc brake grease.

The other thing to be careful of when using the grinder without the handle is make sure not to cover the fan with your hand.

Dewalt recommends using a polyurea grease NLGI Grade 2 in the gear box.

Also if it's getting too too hot your not letting the tool do the work I went through my first angle grinder by feeding it to hard and it burned up got really hot then cought fire both electrically and mechanically speaking. Just ease the grinder around don't push it too hard.
