<human>: Is a sandblasting machine better than a sander?
<bot>: No, Sandblasting is not necessarily better than using a sander. Sandblasting uses a stream of abrasive material to blast away surface material and can cause damage to the underlying material if used improperly. A sander will use a rotating abrasive disk or belt to remove material from a workpiece. The result is generally smoother and more even surfaces with less risk of damaging the underlying material.
