Tips and Tricks for using Taps & DIes

1. Always start threading slowly to ensure alignment and prevent cross-threading 
   
2. Use cutting oil generously to reduce friction and extend tool life 
   
3. Reverse the tap or die occasionally to break chips and prevent jamming 
   
4. Match metric or imperial threads carefully to avoid incompatibility 
   
5. Practice on scrap material before working on critical parts to gain confidence
