Types of Hole Cutting Tools
6mm multipurpose drill bit
A 6mm multipurpose drill bit is a tool for drilling into a wide variety of materials, including wood, tile, glass, brick, concrete, and some metals like cast iron and stainless steel. It's designed to handle tough jobs and is a versatile option because it can often drill through materials that would typically require different, specialized bits.
Diamond hole cutter for tiles
A diamond hole cutter for tiles, also known as a diamond hole saw or diamond core bit, is a specialized cutting tool with a diamond-grit-coated edge used to create clean and precise holes in hard materials like porcelain, ceramic, glass, granite, and marble. Unlike standard bits, these tools cut by grinding away the material, requiring water as a coolant and a specific drilling technique starting at a 45-degree angle to prevent damage and extend the tool's life.

Application of Hole Cutting Tools
