Every Bantam Tools Desktop CNC Milling Machine ships with a pre-installed Bantam Tools Desktop T-slot Bed. But it's always a good idea to have a few T-slot beds as a backup, so that you have the ability to keep prototyping aluminum parts no matter what happens. Combined with our toe clamps and L-bracket, this fixturing accessory offers quick, easy, and reliable workholding solutions for a variety of jobs.
