Diamond Blades & Core Bits for Tile & Stone

Diamond Blades & Core Bits provide cutting and drilling solutions for compatible ceramic, porcelain, glass, natural stone, and other hard materials. Used with appropriate tile saws, grinders, drills, and other power tools, diamond blades support cutting, trimming, and compatible grinding applications, while core bits create circular openings for pipes, fixtures, anchors, and other installation penetrations.

Types of Diamond Cutting & Drilling Tools

Wet & Dry Diamond Blades

Wet diamond blades are designed for compatible equipment that supplies water to the cutting area to help manage blade heat and airborne dust. Dry diamond blades operate without water and provide an option for compatible tools and applications where wet cutting is not practical. Blade diameter, arbor, rim design, material compatibility, and permitted cutting method vary by product.

Cutting & Grinding Diamond Blades

Some diamond blades are designed to support both cutting and compatible grinding or shaping applications. These blades can provide additional versatility for edge work and material removal, but permitted uses depend on the individual blade and power tool specifications.

Diamond Core Bits

Diamond core bits create circular openings in compatible tile, porcelain, stone, glass, and other hard materials. Available diameters and wet or dry configurations accommodate different hole sizes and drilling applications, while shank or connection types vary according to the compatible drilling equipment.

Diamond Tools for Different Materials

Porcelain, ceramic, glass, and natural stone have different cutting and drilling characteristics, making material compatibility an important consideration when selecting diamond tools. Blade or bit design, operating method, diameter, connection, and tool compatibility should be matched to both the material and intended application.

Choosing Diamond Blades & Core Bits

Choose diamond blades based on material compatibility, blade diameter, arbor, rim or segment design, wet or dry operation, and the cutting or grinding work required. For core bits, compare hole diameter, shank or connection type, wet or dry drilling requirements, material compatibility, and the specifications of the power tool being used.

Frequently Asked Questions

What is the difference between a diamond blade and a diamond core bit?

A diamond blade uses its cutting edge to cut through or work along compatible tile and stone materials. A diamond core bit cuts around the perimeter of a circular opening to remove a core of material. Blades are primarily used for cutting and shaping, while core bits are designed for drilling holes.

What materials can diamond blades cut?

Diamond blades are available for ceramic tile, porcelain tile, natural stone, glass, and other compatible hard materials. Exact capabilities depend on the blade design and specifications. Match the blade to the material, power tool, blade diameter, arbor, operating speed, and required wet or dry cutting method.

What is the difference between wet and dry diamond blades?

Wet diamond blades are designed for compatible cutting systems that deliver water to the blade and cutting area, while dry blades are designed for approved cutting without a water supply. Blade construction and permitted applications vary, so always follow the blade and tool manufacturer's requirements for wet or dry operation.

What type of diamond blade should I use for porcelain tile?

Choose a diamond blade specifically compatible with porcelain and the power tool being used. Porcelain is dense and can be demanding to cut, so consider the blade's material rating, diameter, arbor, rim design, wet or dry cutting requirements, and recommended operating specifications rather than selecting a blade by appearance alone.

What are cutting and grinding diamond blades used for?

Cutting and grinding diamond blades are designed for compatible applications that may involve cutting along with edge shaping, beveling, or material removal. Capabilities vary significantly between blade designs, so verify the manufacturer's permitted uses, material compatibility, mounting requirements, and operating specifications before using a blade for grinding or shaping.

What are diamond core bits used for?

Diamond core bits create circular openings through compatible tile, porcelain, stone, glass, and other hard materials. During tile installation, different bit diameters can be used to create openings for plumbing pipes, valves, fixtures, anchors, and other penetrations. Material and tool compatibility should be verified before drilling.

Should I use a wet or dry diamond core bit?

Use the drilling method specified for the particular diamond core bit. Wet core bits require or are designed for water during drilling, while dry core bits are engineered for approved use without a water supply. Some products may support additional operating methods, so follow the bit manufacturer's specifications rather than assuming interchangeability.

How do I choose the right size diamond core bit?

Select the core bit diameter according to the required finished opening and the component that must pass through it. Then verify that the bit's material rating, connection or shank, wet or dry drilling method, and recommended operating specifications are compatible with the material and drilling equipment being used.
