- Reposition and secure the sheet if necessary before drilling.
Adjusting The Rotational Speed Of The Drill
When drilling holes in plexiglass, setting the rotational speed of the drill properly is crucial. The rotational speed should be adjusted based on the diameter of the hole and the thickness of the material. Starting with a low rotational speed is recommended to minimize the risk of cracking or melting the plexiglass.
Here are some key points to keep in mind:
- Larger holes and thicker materials generally require lower rotational speeds.
- It is important to experiment with different speeds and observe the performance to determine the optimal rotational speed for your specific drilling operation.
- Adjusting the rotational speed allows for better control, reducing the chance of damaging the plexiglass and ensuring clean and precise holes.
