FAQs
What is the purpose of the taper and plug taps?
The taper tap is used to start the thread, while the plug tap is used for finishing and threading through holes.
What kind of cutting oil should I use?
Use a high-quality cutting oil specifically designed for metalworking. This will improve thread quality and extend the life of your tools.
How do I choose the right tap or die size?
Refer to a BSW thread chart to determine the correct size for your bolt or hole. The set includes a thread gauge to help with identification.
What should I do if a tap gets stuck?
Try reversing the tap slightly to break the chip, apply more cutting oil, and gently work the tap back and forth. If necessary, use a tap extractor.
How should I store the tap and die set?
Always store the set in its original case to protect the tools from damage and ensure they remain organized.
Can I use this set on stainless steel?
While the set can be used on some steels, it's generally best suited for softer metals. Stainless steel may require specialized tools.
What if the thread is still not accurate after using the tools?
Make sure your workpiece is correctly aligned. The issue may be with the workpiece rather than the tool, or it may be because you are using the wrong tool for the job. Please refer to thread standards.
Troubleshooting
Tap or die breaks during use.
Reduce cutting speed, apply more cutting oil, or ensure the workpiece is securely held. Also, make sure you are using the correct size and type of tap or die.
Threads are cross-threaded or inaccurate.
Ensure the tap or die is started straight. Use the self-centering die holder for improved accuracy. Check that you've selected the correct size.
Die holder won't hold the die securely.
Check the die holder's mechanism and make sure it is clean and functioning correctly. Replace the holder if damaged.
