When tapping by hand or machine, how should you apply pressure at the start?

• A. A firm downward pressure until started
• B. A quick tap with light pressure
• C. Upward pressure to seat the tap
• D. No pressure until engagement

Answer: (A)

When tapping, the cutting action begins only after the tap’s edges bite into the material. Apply a steady, firm downward pressure at the start so the tap stays aligned and can begin cutting the first threads. This initial bite is what establishes the proper engagement; if you use only a light tap or lift upward, the tap won’t start or will wander out of alignment, and nothing will be cut yet. Maintain that steady pressure as you feed the tap, and use proper lubrication to help the cutting action continue smoothly.
