Our gold tooling is machined turned right here in the USA and engineered to not only handle a wide variety of material types and hardnesses but it is also manufactured to a specific tolerance to ensure the most accurate and trouble-free drilling today. That is why we call it tooling, the same high quality used in high-speed machine shop operations. As a technician, we know your time is valuable, so we designed our bits to punch through quickly and accurately to deliver the predictable results you expect.
