This type of reamer is made of a single piece of hard alloy and features high hardness, high strength and excellent wear resistance. Machine reaming cutters can achieve high-precision and high-efficiency reaming processing for various metal materials, such as steel, cast iron, and aluminum alloys. Premium HSS Material for Superior Performance：Crafted from high-speed steel (HSS), this reamer offers exceptional hardness and heat tolerance. Adjustable Range for Versatile Hole Sizing：Featuring an adjustable design, this reamer allows to customize the diameter within a specific range. It adapts to various hole sizes, reducing the need for multiple tools and enhancing work efficiency and cost-effectiveness. Wide Material Compatibility for Diverse Applications：Suitable for A3 steel, alloy steel, cast iron, cast steel, aluminum, and other metal materials. Precision Reaming for Smooth, Accurate Holes：Designed for finishing drilled or pre-reamed holes, this tool removes a thin layer of metal from the hole surface. It improves dimensional accuracy and reduces surface roughness, making it ideal for semi-finishing and finishing operations., Manufacturer: SUPKOUMKBG
