FAQs

What materials can I use this set on?

The set is suitable for use on a variety of materials, including mild steel, aluminum, and some plastics.

What is the difference between taper, secondary, and bottoming taps?

Taper taps start the thread, secondary taps are for general use, and bottoming taps cut threads to the bottom of a blind hole.

How do I choose the correct drill size for the tap?

The drill size is indicated on the tap package or in a reference chart. Always use the correct size to ensure the thread fits properly.

What should I do if a tap gets stuck?

Try to remove the tap by turning it backward, applying penetrating oil may help. If it breaks, use an extractor tool or seek professional assistance.

How should I store the tap and drill set?

Store the set in its case in a dry environment to prevent rust and damage.

Can this set be used for creating threads in stainless steel?

While it can be used on stainless steel, it is recommended to use cutting fluid specifically designed for stainless steel to prolong the life of the taps and drills.

Troubleshooting

Tap breaks during threading

Ensure the drill hole is the correct size. Apply sufficient cutting fluid. Avoid excessive force and turn the tap slowly. Use the correct tap for the task, starting with the taper tap.

Drill bit breaks

Apply even pressure and avoid excessive speed when drilling. Ensure the drill bit is sharp and in good condition. Use the correct speed and feed rate for the material being drilled.
