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. 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. Advanced Coating：Features a specialized coating that enhances heat resistance and reduces friction during cutting operations. This protective layer significantly extends tool life and improves overall machining efficiency. Constructed from premium tungsten carbide alloy with a hardness of up to HRC 60°, this drill bit offers exceptional wear resistance and rigidity. It is specifically engineered to drill through hard metals, including stainless steel, cast iron, and hardened steel, without losing its edge., Manufacturer: SUPKOUMKBG
