Darex brands include Darex industrial bit sharpeners, Drill Doctor professional and DIY drill bit sharpeners, and Work Sharp knife and tool sharpeners. Darex began in 1973 in Beecher, Illinois. We design, engineer, and assemble our sharpening machines all under one roof - also shared by our in-house customer service, sales, and admin teams. We source as many components from North American manufacturers as we can, and insist our over-sea suppliers meet stringent quality control metrics and share in our practice of creating a great work place for their employees
