Use Instructions – VEVOR 116PC Tap and Die Set

1. Choose the Correct Tap or Die:

   • Identify the required thread size and pitch using the screw pitch gauges provided.

   • You can select from 51 taper taps, 51 plug taps, or matching dies (including metric and SAE sizes).

2. Prepare the Material:

   • Secure the workpiece using a vise.

   • For internal threads, drill the correct pilot hole size (refer to a tapping chart).

   • For external threads, clean and slightly chamfer the rod end.

3. Mount the Tool:

   • Insert the selected tap into a tap wrench (choose M3–M12 or M6–M20).

   • Place the die into the die wrench (25mm or 38mm, as needed).

   • Use the T-type tap wrench for better control in tight spaces or smaller taps.

4. Threading Operation:

   • Apply cutting fluid or lubricating oil to minimize friction and extend tool life.

   • For tapping: turn clockwise with even pressure; after every full turn, reverse a half-turn to clear chips.

   • For dies: align carefully and turn gently to start the thread. Continue with the same forward/reverse method.

5. Post-Threading:

   • Back the tool out slowly.

   • Clean threads with a wire brush or cloth.

   • Wipe down and oil the tap/die before returning it to the case.

6. Use Additional Tools:

   • Screwdriver: This is used to adjust die tension or perform tool maintenance.

   • Screw Extractors: Remove broken bolts or damaged threads by drilling a pilot hole and turning counterclockwise.

Precautions

• Lubricate before use to reduce wear and avoid overheating.

• Do not force the tool—this can cause breakage, especially in hard or stainless steel.

• Always align properly to prevent cross-threading.

• Avoid using hardened materials beyond the alloy steel taps and dies rating.

• Clear chips frequently to ensure smooth operation.

• Clean and oil tools after use to prevent rust and prolong life.

• Secure workpieces firmly—slippage can damage both the tool and the material.

• Store the tap and die set in the original case to keep the 116 pieces organized and protected.
