Diamond Blades & Core Bits for Tile, Porcelain & Stone

Diamond blades and core bits are cutting and drilling tools designed for use with saws, grinders, and drilling equipment to process tile and stone materials during installation. These tools utilize industrial diamond segments or diamond-coated cutting surfaces to cut, grind, and drill through hard materials commonly encountered in tile and stone work, including ceramic, porcelain, and natural stone.

This collection includes diamond blades for straight cutting, specialty cutting, and material shaping, along with core bits used to drill clean, circular openings through tile and stone surfaces. Diamond blades and core bits play a critical role in accurate layout, fixture installation, and material preparation for both residential and commercial projects.

Types of Diamond Blades for Tile & Stone

  • Continuous Rim Blades: Designed for smooth, clean cuts in porcelain, ceramic, and stone
  • Turbo Rim Blades: Provide faster cutting with controlled edge quality
  • Segmented Blades: Used for aggressive cutting and material removal
  • Wet & Dry Blades: Available for wet cutting, dry cutting, or dual-use applications

Types of Diamond Core Bits

  • Wet Core Bits: Designed for use with water to control heat and extend tool life
  • Dry Core Bits: Used without water for fast drilling in tile and stone
  • Vacuum-Brazed Core Bits: Provide rapid drilling and multi-material capability

How to Choose

  • Material Type: Match the diamond blade or core bit to ceramic, porcelain, stone, or glass
  • Wet or Dry Use: Confirm whether water is required, optional, or not recommended
  • Cut Quality vs. Speed: Continuous rims favor clean cuts, segmented styles favor faster material removal
  • Tool Compatibility: Verify arbor size, shank type, and recommended RPM ratings

Common Applications

Diamond blades and core bits are used for floor and wall tile installations, backsplashes, showers, countertops, and general stone fabrication. Core bits are commonly used to drill openings for plumbing pipes, valves, anchors, and electrical penetrations. These tools support accurate cutting and drilling that helps installers achieve proper fit, clean edges, and professional installation results.
