4.125" (105mm)：Cylinder Hone, 240 Grit Silicon Carbide, 4-1/8" (105mm) Diameter for Hole Diameters 3.751"-4.125", Ball Hone for Mild Steel, Stainless Steel, Cast Iron

This cylinder hone is made of high-quality 240 grit silicon carbide, which has excellent cutting performance and wear resistance. The ball-shaped abrasive structure can fully contact the inner wall of the cylinder, effectively removing burrs, rust, carbon deposits and surface defects, improving the surface finish of the cylinder bore. It is suitable for processing mild steel, stainless steel, cast iron and other ferrous materials, and is widely used in engine maintenance, mechanical processing, pipeline finishing and other fields. We provide multiple size options to meet different bore diameter requirements, which is convenient for you to choose according to actual needs.
