Setup, Compatibility & Care
To begin your repair, ensure you have a firm workbench setup and appropriate lubrication for the tapping process. This kit is strictly designed for M12 x 1.5 thread specifications; attempting to use these components on different thread pitches will result in failure. Always ensure the drill bit is perpendicular to the surface before starting to prevent off-center holes. Post-installation, keep the remaining kit in a dry, organized tool box to prevent corrosion on the carbon steel taps and drill bits. If the kit remains idle for long periods, consider applying a light coat of machine oil to the taps to prevent surface rust.
