Another similar process to shot peening is called ‘Shot blasting ‘, which create a very similar result as shot peening, but shot blasting use a high RPM spinning wheel creating a centrifugal acceleration to ‘throw' the media onto the workpiece's surface. It is used in larger workpieces which requires more aggressive forces to make a stronger surface. However, for complicated shape, sometimes it leaves some ‘dead corner' not blasted.

As shot blasting and shot peening could cause much harder collateral damage than sandblasting, stronger and better containment is required. Sandblasting is often operated by labors while shot blasting and shot peening often run automatically or semi-automatically.
