FAQs
What type of threads does this set work with?
This set is specifically designed for Whitworth Standard (BSW) threads. It is not suitable for metric or UNC/UNF threads.
What is the difference between taper and plug taps?
Taper taps have a gradual chamfer and are used to start a thread, especially in blind holes. Plug taps have a shorter chamfer and are used for finishing threads, often after a taper tap.
How do I maintain the taps and dies?
After each use, clean them thoroughly to remove any metal shavings or cutting fluid. Apply a light coating of oil to prevent rust, especially for storage. Store them in their case.
Can I use this set for both cutting new threads and cleaning existing ones?
Yes, this set is suitable for both cutting new threads and for cleaning or repairing existing threads.
What materials can I use these taps and dies on?
These taps and dies are made from alloy steel and are suitable for use on most common metals, including steel, aluminum, and brass. For harder metals, ensure you use appropriate cutting fluid and apply firm, steady pressure.
What is included in the set?
The set includes 1 tap wrench, 1 die handle, 14 taps (various plug and taper sizes from 1/8" to 1/2"), and 7 dies (various BSW sizes from 1/8" - 40 to 1/2" - 12), all housed in a metal storage case.
Troubleshooting
Tap breaks during use
Ensure you are using adequate lubrication (cutting fluid), not forcing the tap, and backing it out periodically to clear chips. Use the correct tap type (taper for starting, plug for finishing).
Die cuts incorrectly or binds
Verify the correct die size is being used. Ensure the die is held perfectly square to the workpiece and that cutting fluid is applied. Do not over-tighten the die handle.
Difficulty starting a thread
Use the taper tap first to create a pilot hole. Ensure the starting surface is clean and appropriately prepared. Apply cutting fluid.
Rust on taps or dies
Clean the affected area with a fine-grade steel wool and re-apply a light coat of oil for protection. Ensure proper storage in a dry environment.

Setup, Compatibility & Care
Setup:
Identify the correct tap or die size for the desired thread.
Insert the tap into the tap wrench or the die into the die handle, ensuring it is securely fastened.
For tapping, apply cutting fluid to the tap and the workpiece. Start by carefully aligning the tap perpendicular to the surface and turning the wrench clockwise, applying gentle pressure. Back off the tap periodically to clear chips.
For dieing, apply cutting fluid. Align the die with the bolt or stud and turn the die handle clockwise, taking care to keep it square.

Care:
Clean taps and dies thoroughly after each use to remove debris and cutting fluid.

Store components in their designated slots within the metal case to prevent damage and loss.
