# 4.6.2 Entering the oval inputs (step-by-step)

This page is the step-by-step companion to 4.6.1. The four oval inputs — **starting bit, oval width, oval degree, and taper** — are defined in 4.6.1, and the calculation that turns them into drilling movements is covered in 4.6.3 and the **Oval Calculator (Book 05)**.

1. Set the thumb shape to **Oval** (4.5.1).
2. Enter the **starting bit** diameter.
3. Enter the **oval width** (finished width, including clearance).
4. Enter the **oval degree** (orientation of the width axis).
5. Enter the **taper**.
6. Confirm all four values, then review the calculated oval cut (4.6.3) before drilling.

**Tip:** Print or display the spec sheet at the press before you start — having the four inputs and the calculated output visible throughout the cut prevents errors from misremembering a value mid-drill.
