These abrasive tools are composed of aluminum oxide, a naturally occurring mineral also known as corundum. Their high hardness and durability make them suitable for various applications, including cutting, grinding, and drilling hard materials like stone, metal, and concrete. The bits themselves are manufactured in diverse shapes and sizes depending on the intended use, ranging from small points for delicate work to larger, more robust forms for heavy-duty applications. Examples include those used in rotary tools for precise shaping or larger ones employed in drilling machinery.
The exceptional hardness of these implements contributes to significant improvements in efficiency and longevity compared to other abrasive materials. This translates to reduced operational costs and downtime. Their consistent performance across numerous applications has led to widespread adoption across various industries, from construction and mining to manufacturing and precision engineering. Historically, the use of naturally occurring corundum predates modern manufacturing techniques, highlighting the material’s enduring value as an abrasive.
Subsequent sections will detail the manufacturing processes involved, explore the various applications in greater depth, and discuss the selection criteria for optimal performance based on material properties and intended use.
