Best Multi-Saw Blades for Stone Cutting


Multi-tool blades come in every shape and size. For any project and for every task, your multi-tool will slice the work in half. It can even see you through projects that seem too tough for a multi-tool. Cutting through cement, brick or stone can be made to look easy and your multi-saw will shine like a star when you use the best blades. However, for the toughest materials like rock, stone, and grout, the best tool to use is a diamond blade saw.

Diamond blades cut through hard, abrasive materials. Instead of cutting like an ATB table saw does with wood, these blades use a harder substance than the one being cut, in order to grind through the material with diamonds. These blades have diamond crystals embedded throughout segments of rectangular teeth. Diamond blades are strong enough for cutting stone concrete, asphalt, bricks, and glass because of the way in which the diamonds are embedded into the saw blade. The manufacturing method is typically one of three variations. Each variation has a different bonding, which enables it to be used for individual materials.

  • Bond

The bond of a diamond blade refers to how soft or hard the metal powder is which holds the diamonds in place. This mixture of diamonds and metal powder are eventually made into saw segments. The rate at which the blade wears—to the point of exposing a new layer of diamonds on a segment—is what the bond controls. When a segment wears down to a new layer of diamonds, a clean, sharp edge is presented and ready for grinding. The softer the bond, the harder the material it is meant to cut.

  • Electroplating

Electroplating involves embedding diamonds into a metal coating made of nickel. Then they go through an electroplating process which involves combining the substance mixture over an electric current to bind them. This results in blades that can be made exceptionally thin for fine precision cuts.

  • Vacuum Brazing

If a diamond saw is vacuum brazed, it basically means that diamond particles were welded onto the edge of a circle saw blade. This typically involves a vacuum brazing furnace and does not result in a chemical bond between the two materials.

  • Sintering

Sintered diamond blades consist of a steel core and segments of diamond. Sintering is the most common technique for creating diamond blades. The process involves combining synthetic diamond crystals with metal powder by pressing the materials together under extremely high pressure. This bonds the materials together, without melting them.

  • Wet and Dry Saws

Most diamond blades want to be used wet. This means that water is poured onto the material while being cut by the diamond blade. There are several reasons for wetting the blade while it is cutting. The main purpose of this is to keep the blade from overheating, which it otherwise would do easily. The harder the material, the more energy is released as heat when the particles are split from the material. The harder the bond, the more heat the cut will make. Water will also greatly reduce the amount of harmful dust created by cutting and remove the slurry from the cut. When running the blade dry, many diamond blades are unable to withstand the higher levels of heat involved in cutting ceramic and abrasive materials. Water will greatly extend the life of the blade.

If water cannot be used during your cut, safety measures should be taken. If you are using an electric saw or any multi-tool that will not tolerate wet blades, breathing protection must be worn, in order to avoid inhaling the fine dust created by diamond blades. This dust is known as a possible cause of the dangerous lung disease, silicosis. Also, allow the blade to cool off every minute or so. Running the blade outside of the cut zone will speed up the cool-down period.

  • Diamond Blade Types

The three types of diamond blades best for cutting stone with a multi-saw are segmented blades, continuous rim blades and turbo blades.

  • Segmented Blades

Often designed with medium to hard bonds, segmented diamond blades are great for many cutting applications. They are useful for both wet and dry cuts and will most certainly last for a long time. These durable blades cut with a medium smoothness and high speed. These stone blades are used for cutting marble and granite slabs, concrete, asphalt, brick, block, and other building materials.

  • Continuous Rim Blades

These blades are designed specifically to tackle hard materials. Continuous rim blades have softer bonds and diamonds are exposed more quickly through the blades life for an ultra-sharp cut. They cut materials that are easily chipped, such as tile, porcelain, granite, stone, glass, and others. These blades feature one segment without breaks and are mostly used for wet cutting.

  • Turbo Blades

Turbo blades are meant for a wide range of general and specific purposes. They are made with a soft to medium bond and typically feature a serrated edge on a single, continuous segment. A turbo blade has the best features from both other types of blade. The continuous, serrated edge makes for fast cutting while remaining smooth and clean. They are mostly used to cut a variety of materials, such as tile, stone, marble, granite, masonry, and many other building materials. Many turbo blades are made for both wet and dry cutting applications.

  • Best Stone Cutting Blades

Stone cutting blades are designed to cut solid rock in half so that it is easier to move. Your blade isn't very useful if you can't get your saw to the material, so get one of the best stone cutting blades for your multi-tool saw, and get mobile. If the rock won't come to you, you got to go to the rock.
