115pc Tap and Die Set - Neilsen - CT2139

Screw extractors are used to remove broken screws or bolts.

Use a cutting oil specifically designed for metalworking. This will help reduce friction and prevent damage to the tools and workpiece.

This set can be used on a variety of materials, including mild steel, aluminum, and certain plastics.

Select the tap or die size that matches the thread size of the bolt or hole you are working with. Use the screw pitch gauges included in the set to determine the thread pitch.

Ensure the tap or die is perfectly perpendicular to the surface. Start the tap or die slowly, checking frequently to ensure it's aligned correctly. Use cutting oil.

Store the set in a dry place to prevent rust. Clean and oil the tools after each use.

Apply more cutting oil and try to carefully reverse the tap or die. If it remains stuck, try using a tap wrench for additional leverage. If all fails, you may need a specialized removal tool or professional assistance.

Ensure the correct size and type of tap or die is used for the material. Apply cutting oil and do not force the tool. If it breaks, use a screw extractor to remove the broken piece.

Make sure the tap or die is aligned correctly with the workpiece. Use cutting oil to reduce friction. If damage occurs, try using a thread restorer die.

Apply more cutting oil. Ensure the tap or die is the correct size. Check for any obstructions or damage to the threads.
