Autojack Metric Tap & Die Set - 40 Piece

Cutting oil reduces friction, helps remove metal shavings, and improves the finish of the threads.

This set is suitable for use on a variety of materials, including steel, aluminum, and plastics. Always ensure the correct tap and die size is used.

Refer to the markings on the tools and match them to the required thread size for your project. Consult a thread chart if necessary.

Use a wire brush and solvent to remove metal shavings after each use. Make sure the tools are dry before storing them.

Carefully try to remove the broken tap using a tap extractor. If this fails, you may need to drill out the tap and re-tap the hole with a larger size.

Insert the tap into the T-Bar Wrench and tighten. Align the tap with the hole, apply even pressure, and turn the wrench clockwise to cut the threads. Reverse direction occasionally to break chips.

Store the set in its metal carry case in a dry place to prevent rust and corrosion.

Ensure you are using the correct size, applying even pressure, and using cutting oil. If necessary, switch to a lower cutting speed.

Ensure the tap or die is started straight and aligned with the hole or rod. If repairing a thread, use a thread chaser or the next size up tap or die.

Apply more cutting oil. Check for any obstructions or debris. Make sure the tap or die is the correct size for the application.
