The MachEl Spring-Loaded Tapping Center is crafted from precision-hardened alloy steel, with a hardened point rated at 50-55 HRC for exceptional durability. Featuring a 12 mm (1/2") shank and an overall length of 85 mm, this tool is designed for universal tapping applications. To use, grip the center's body in a drill chuck or collet, and insert the hardened point into the middle of the tapping handle. The spring-loaded mechanism ensures the stroke of the center follows the tap, maintaining alignment for straight and accurate hand-tapped threads. This versatile tool is perfect for ensuring precision in any tapping task.
