I have a signage company. I broke a piece of acrylic at a construction site trying to use a good quality standard bat (the sign cost me $250 to replace). But even worse, when a well-gagged acrylic plate hits the grooves of a standard racquet, the plate spins, pinning you to your foot. This is the right tool for the job. It cuts through acrylic without cracking or pinching. I don't know if this is any better than other custom acrylic bits, but it worked for me.
