Printing tips
- Set the paper to A4 and the scale to 100% (“Actual size”). The menus, buttons and links are left off the printout automatically.
- Laminate the sheet or put it in a plastic wallet if it will live near coolant.
- You’re welcome to print and share copies for personal and workshop use. Please don’t sell them or republish them as your own.
For one size at a time, every tap drill size page also has its own print button.
