Install AutoHotKey, right-click your desktop and create a new AHK script. It'll open a blank text document, from there copy and paste this...
then save it. Double-click the AHK script you just made on the desktop and now when you press the Right Alt key, it'll be the space bar. You can change it to whatever, I was just using the Right Alt as an example.
Just change the part here ----> ___::Space to whatever key you like.
Here's a list of keys. https://autohotkey.com/docs/KeyList.htm
Shane has gotten to the point where if it isn't a Festool, it's a harbor freight special.
I personally like Makita for my drills, however if I was replacing and my 2 choices were Milwaukee or Dewalt I would go with Milwaukee.
