SMART CUT® Rubber Bond Abrasive Cut-Off Blades are expertly designed for metallography and sample preparation, blending advanced rubber bonding technology with high-grade abrasive materials. These blades are exceptionally well-suited for processing a range of materials, from ferrous and non-ferrous metals to delicate and brittle materials that demand meticulous handling to preserve their structural integrity.
Featuring an innovative rubber bond, these SMART CUT® Rubber Bond Abrasive Cut-Off Blades significantly enhance flexibility and shock absorption, which substantially reduces both vibration and noise during operation. This contributes to smoother operations and extends the blade’s lifespan by minimizing the risks of cracks or breaks under stress. The cutting performance of the rubber bond is distinguished by its ability to make clean, precise cuts with minimal heat generation, thereby maintaining the unaltered metallurgical properties of the sample for precise analysis.
Crafted from sheets of natural rubber using the traditional calendered method, SMART CUT® Rubber Bond Abrasive Cut-Off Blades blades possess a unique composition that renders them ideal for high-quality, cool, burn-free sectioning on metallographic samples. We offer sample wheels tailored to meet your specific sectioning applications for evaluation.
Custom specifications are available upon request, often requiring only small order quantities and featuring very fast lead times. We offer sample wheels tailored to meet your specific sectioning applications for evaluation.

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. |
