Attempt to index nil with 'Hit'?

This is my script:

local Tool = script.Parent
local cool = false -- Debounce
local mouse = game:GetService("Players").LocalPlayer:GetMouse()
Tool.Activated:Connect(function(mouse)
	if cool == false then
		cool = true
		local pos = mouse.Hit.Position  -- Error here
		Tool.RemoteEvent:FireServer(pos)
		wait(1)
		cool = false
	end
end)

This is a local script and I put this in a tool. I'm trying to get the player's mouse position and send it to the script that activates when the remote event is fired. This error stopped all of my script. How can I fix this?
