Printable Shop Reference Sheets
A hub for clean print views of drill, tap, clearance, and pilot-hole charts.
What belongs on a printed shop sheet
A good printed sheet should include the values that are needed at the bench: drill size, decimal equivalent, metric equivalent, tap size, and a short caution about assumptions. Long explanations are better kept on the screen.
Print one workflow per sheet
Keep tap drill charts, clearance holes, screw pilot holes, and NPT references separate enough that the user can find the right table quickly. Combining everything into one dense page makes lookup slower.
Keep the web page as the maintained source
Printed charts drift out of date. The printable pages should link back to the canonical chart pages so corrections and source notes remain traceable.
