Different types of rotary bits, such as abrasive, backing, and burr, can cause a grinder to catch on rough material edges or shift around. Understanding the characteristics of these rotary bits is crucial for effective and safe grinding operations.
Abrasive rotary bits can cause a grinder to catch on rough material edges or shift around due to their rough texture that can grab onto the material unevenly. This can lead to sudden movements of the grinder, making it challenging to handle.
Backing provides support to the abrasive material and helps in maintaining stability during grinding. Without proper backing, the abrasive bit may not perform effectively and could potentially cause the grinder to catch or shift.
Burr rotary bits, especially if not properly sharpened or maintained, can create uneven cutting edges, leading to the grinder catching or moving irregularly on the material.
