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. Premium Carbide Material：Made from carbide, this end mill delivers exceptional hardness and wear resistance for long-lasting performance. It maintains sharp cutting edges even under high-speed machining conditions., Manufacturer: SUPKOUMKBG
