Cursor change help

i need help. I’m currently making a game where your a doctor of robots and fix them but i have run into a snag. I need to have something where you have buttons on the screen (I can do that) but where when you click them it changes the cursor and that has its own properties so like the hand can move things around but then you click on the cutter and that can cut the metal skin.

HELP ME!

Don’t think your help wont be unoticed as you WILL be included in the credits when the game gets put onto the internet.
