You are mistaken. Liquid Resins does assemble their own drills and repairs them when necessary. In glass repair, high speed drills are not necessarily better. The more speed, the more heat generated! The Liquid Resins drill has a keyless chuck and a momentary switch so the drill bit can be slowly "burped in". This helps make your bits last longer and helps keep from scorching the inside of the drill hole or the plastic inter layer.
