Review on Precision Made Simple: PROTRAC06 6 Inch Marking Protractor for Accurate Measurements by Kevin Griffin

Amazing little protractor. I also use it as a makeshift center finder. This protractor comes with an official 0.5mm mechanical pencil. It's a little tight but definitely doesn't sag so it creates the perfect line. I need to find a pen or permanent marker with a very fine tip for plastics and metals that don't hold a pencil well. Overall, this is a very accurate and well-built measuring and marking tool. If you want to mark right the first time, use Incra. Everyone should have one of their tool kits along with the 6 inch Incra-T rule.
