The Insize ISR-CS2 Surface Roughness Specimen Set is a practical reference tool designed for checking, identifying, and comparing surface roughness by visual and tactile inspection. It enables machinists, inspectors, and engineers to quickly verify surface finish standards across a range of machining processes. Manufactured from durable carbon steel, each specimen is precisely finished to represent specific roughness values (Ra and Rz). This set is ideal for workshop use, training, quality control, and inspection environments where quick surface finish comparison is required without the need for electronic instruments. Key Features & Benefits Used for checking, identifying, and specifying surface roughness by comparison Covers multiple machining methods including milling, turning, and grinding Includes a wide range of Ra and Rz roughness values Made from durable carbon steel for long service life Ideal for workshop, inspection, and training applications Compact set supplied in protective case for easy storage Technical Specifications Part Number: ISR-CS2 Product Type: Surface Roughness Specimen Set Material: Carbon Steel Machining Methods Included: Horizontal Milling Vertical Milling Turning Plain Grinding Flat Lapping External Grinding Roughness (Ra): Milling & Turning: 0.4, 0.8, 1.6, 3.2, 6.3, 12.5µm Plain Grinding: 0.05, 0.1, 0.2, 0.4, 0.8, 1.6µm Flat Lapping: 0.05, 0.1µm External Grinding: 0.2, 0.4, 0.8, 1.6µm Roughness (Rz): Milling & Turning: 1.6, 3.2, 6.3, 12.5, 25, 50µm Plain Grinding: 0.2, 0.4, 0.8, 1.6, 3.2, 6.3µm Flat Lapping: 0.2, 0.4µm External Grinding: 0.8, 1.6, 3.2, 6.3µm Quantity: Horizontal Milling: 6 pcs Vertical Milling: 6 pcs Turning: 6 pcs Plain Grinding: 6 pcs Flat Lapping: 2 pcs External Grinding: 4 pcs Insize is a globally recognised manufacturer of precision measuring tools, offering reliable and high-quality inspection solutions trusted across engineering, machining, and industrial environments worldwide.
