The use of a 1" grinding stone to bevel bolt holes is prohibited because it can lead to uneven surfaces and inadequate preparation of the holes. Proper beveling is essential for ensuring that the bolts fit snugly and securely, thus maintaining structural integrity. Using a tool that is not suited for this task, such as a grinding stone, can compromise the effectiveness of the welding process and potentially lead to failure in the joint. In most welding practices, standard procedures and tools are specified to ensure safety and the quality of the weldments. Dedicated beveling tools or techniques are recommended to achieve the necessary precision and finish.
