Manufacturers in this sector employ advanced technologies, such as CNC machines and heat treatment processes, to create button bits with precise dimensions and strength. The production begins with the selection of high-grade raw materials, followed by forging, heat treatment, threading, and finally, the insertion of the tungsten carbide buttons. Quality control is rigorous at every stage, with each batch undergoing stringent tests for hardness, toughness, and resistance to wear and impact.

The hardness of limestone can vary greatly, from relatively soft to extremely hard, depending on factors such as its mineral content and degree of compaction. Soft limestones can be easily drilled using standard drilling equipment, but harder varieties often necessitate more robust machinery and specialized bits. Carbide-tipped drill bits, for instance, are commonly employed due to their durability and ability to withstand the abrasive nature of limestone.
