High speed machines and faster throughput demands a close tolerance highly accurate tool. For this reason, H3D Tool Corp. performed extensive research on heads and tools manufactured by US companies as well as foreign suppliers. Some of the tools were acceptable, but by far, repeatability appeared to be the main issue from tool to tool even from the same manufacturer. This is where H3D Tool Corp. makes a difference. Through tough machining standards, very low tolerance zones, and tight machinery calibration, our tools are consistently manufactured resulting in no surprises when you install the tool on your machine.
