The double round edge mill file is a hand tool used for cutting and grinding applications. It is made from T12 high-carbon tool steel with a carbon content of 1.15%–1.25% (equivalent to 1095, Cr06, or 130Cr2). The product hardness ranges from HRC60 to HRC65. It is suitable for sharpening blades, repairing metal workpieces, and correcting flat surfaces. The product is manufactured in accordance with GB 5803–5815, GB/T 806, U.S. Standard GGG-F-325b, and European Standard DIN 6261–7285.Production processes include hot forging, grinding, tooth cutting, quenching, and surface sandblasting.
