20pc Tap and Die Set - M3-M12

The set is suitable for a variety of metals including mild steel, aluminum, brass, and copper. For harder metals like hardened steel or stainless steel, extra care, lubrication, and potentially specialized tooling may be required.

No, this is a 20-piece tap and die set. Tap wrenches and die stocks are typically sold separately and are required for operation.

The correct pilot hole size is crucial for proper threading. Generally, it's the desired thread's major diameter minus the thread's pitch. Consult a tap drill chart for precise recommendations based on the specific tap size.

This set is designed for standard right-hand threads. It does not include components for cutting left-hand threads.

After use, clean each tap and die thoroughly to remove debris. Apply a light coat of oil or a rust inhibitor before storing in a dry place to prevent corrosion and maintain cutting edge sharpness.

Please refer to the manufacturer's warranty information provided with your purchase for specific details on coverage and duration.

Yes, this set is ideal for cleaning up and repairing damaged or corroded threads on bolts, screws, and pipes. Ensure you use appropriate lubrication and steady pressure.

This often occurs from forcing the tap, not using lubrication, or turning backward too often. Ensure you are using cutting fluid and only turning clockwise. If it breaks flush, specialized broken tap extractors may be needed.

Ensure the die is sharp and properly seated in the die stock. Use adequate lubrication and apply consistent, even pressure. Make sure you are using the correct die size for the material.

Ensure the pilot hole is the correct size for the tap. Start the tap by hand with gentle pressure, ensuring it is perfectly straight before applying force with the wrench. Use lubrication.

This can be due to lack of lubrication, the material being too hard, or dull cutting edges. Increase lubrication, ensure the correct pilot hole size, and check if the tool needs sharpening or replacement.
