SMART CUT® Rubber Bond Abrasive Cut Off Blades (Aluminum Oxide & Silicon Carbide)

SMART CUT® Rubber Bond Abrasive Cut Off Blades are solid core wafering blades designed for controlled, low-heat sectioning in metallography and materials sample preparation.

SMART CUT®  blades are manufactured using a continuous rubber bond matrix, where the abrasive is uniformly distributed throughout the entire blade thickness. The rubber bond provides a compliant cutting action that reduces heat generation, minimizes vibration, and delivers a smooth and stable cut. This construction helps preserve microstructure and prevent thermal damage, making these blades well suited for sensitive or critical samples.

Used on: All Low  & High Speed Wafering Saws & Sectioning Saws such as: BUEHLER, STRUERSL, LECO & many others

Selecting Right Abrasive Type for your Application

Aluminum Oxide Rubber Bond Ultra Thin Abrasive Cut Off Wheels

Silicon Carbide Rubber Bond Ultra Thin Abrasive Cut Off Wheels

Aluminum oxide rubber bond cut off wheels are intended for metallographic sectioning of ferrous materials on precision sectioning saws and low speed saws. The rubber bond minimizes heat generation and mechanical stress, helping maintain surface integrity and microstructural accuracy.

Typical applications include carbon steel, alloy steel, stainless steel, tool steel, and cast iron. These wheels provide stable cutting behavior, smooth cut surfaces, and reliable performance for routine metallographic sample preparation.

Silicon carbide rubber bond cut off wheels are designed for metallographic sectioning of non ferrous and non metallic materials on precision sectioning saws and low speed laboratory saws. The rubber bond provides cool, controlled cutting with reduced vibration and minimal sample deformation.

These wheels are well suited for aluminum, copper, brass, nickel alloys, ceramics, glass, composites, and similar materials. They produce clean sections with preserved microstructure and consistent performance at an economical cost.

SMART CUT® Rubber Bond
Aluminum Oxide Abrasive Cut Off Blades

SMART CUT® Rubber Bond Aluminum Oxide Abrasive Cut-Off Blades are solid core wafering blades designed for controlled metallographic sectioning of ferrous materials.

These blades use a continuous rubber bond matrix that provides a compliant cutting action, helping reduce vibration, control cutting forces, and limit heat generation at the cut interface. This makes them well suited for applications where sample integrity and surface quality are critical.

Aluminum oxide rubber bond blades are recommended for ferrous metals and super alloys, including carbon steel, alloy steel, and stainless steel. The compliant bond helps reduce smearing and deformation on ductile metals during sectioning. Compared to resin bond blades, rubber bond aluminum oxide blades are optimized for high spindle speed with light feed pressure, such as on non-gravity-fed metallographic saws. Resin bond blades remain the preferred choice for high-load and high-throughput cutting, while rubber bond blades are used when cooler cutting and improved control are required.

SMART CUT® Rubber Bond Aluminum Oxide Abrasive Cut-Off Blades are available with standard 1/2 inch (12.7 mm) arbors and are compatible with most metallographic sectioning machines.

SMART CUT® Rubber Bond
SILICON CARBIDE Abrasive Cut Off Blades

SMART CUT® Rubber Bond Silicon Carbide Abrasive Cut-Off Blades are solid core wafering blades designed for controlled metallographic sectioning of non-ferrous and non-metallic materials.

These blades are manufactured with a continuous rubber bond matrix that delivers a compliant, low-force cutting action, helping reduce vibration and limit heat generation at the cut interface. This makes them well suited for applications where thermal control and surface integrity are critical.

Silicon carbide rubber bond blades are recommended for non-ferrous metals and softer materials, including aluminum, copper, nickel, and their alloys. The sharp silicon carbide abrasive combined with the rubber bond helps reduce blade loading and smearing when sectioning ductile or gummy materials.

Compared to resin bond silicon carbide blades, rubber bond blades are optimized for high spindle speed with light feed pressure, such as on non-gravity-fed or precision metallographic sectioning saws. Resin bond blades remain the preferred choice for higher cutting loads and faster material removal, while rubber bond blades are selected when cooler cutting and improved control are required.

SMART CUT® Rubber Bond Silicon Carbide Abrasive Cut-Off Blades are available with standard 1/2 inch (12.7 mm) arbors and are compatible with most metallographic sectioning machines used in laboratory and quality control environments.
