Usage guidance

1. Drill the appropriate pilot hole or clearance hole for M4x0.7 tapping according to standard tapping guidelines.
2. Secure the workpiece and apply a suitable cutting fluid to reduce friction and heat buildup.
3. Align the tap perpendicular to the workpiece and begin turning with a tapping wrench or suitable machine tool.
4. Turn slowly, maintaining steady pressure; back off occasionally to break chips and re-clearing the hole.
5. Test fit a corresponding fastener and clean the threaded hole after tapping.

Care and maintenance

After use, clean away chips and oil, wipe dry, and store in a dry location. Inspect the tap for any signs of wear or misalignment before the next job, and use the correct tapping tool to avoid putting undue stress on the cutting edges.
