6PCS HSS Circular Saw Blades Mandrel Rotary Tool Set Fits Dremel Drills Rotary Cutting Blade

Features: Process features: After the air hammer repeated forging, so that the organizational structure of the grain (carbide) refinement, so as to achieve its super metal hardness and wear resistance of the effect. In high speed to play high-speed steel super fatigue resistance fracture performance. Thereby extending its life, and ultimately to save customers time and save energy for the purpose of saving. Processing technology features: the use of CNC machine tools on the blade repeatedly surface rough grinding processing, so that the surface finish to achieve high standards. At the same time also use imported micro-digital control machine blade on the blade (triangular edge and arc edge), the product reached the same level of domestic leading level. Heat treatment process: high-speed steel saw blade: generally in the 1205 ~ 1215 ℃ salt bath quenching, quenching organization metallographic level of 10 to 11, and then class isothermal, hot folder, tempering 4 times, tempering process is not allowed to overheat, the final Tissue hardness 64 ~ 66.5HRC. Use Note: When installed, saw the pole to install the electric mill must be inserted in the end, because the electric grinding speed is high, saw blade is large, the clip will lead to less pole off. At the same time to meet the requirements of the use of the case as far as possible the use of small diameter saw blade. Speed ??must not exceed 10,000 rpm. Package include: 1 X HSS Saw Blade(7/8 ” /22 mm) 1 X HSS Saw Blade(1″ /25 mm) 1 X HSS Saw Blade(1 1/4 ” /32 mm) 1 X HSS Saw Blade(1 1/2 ” /35 mm) 1 X HSS Saw Blade(1 3/4 ” /44 mm) 1 X Extension Rod：1/8 ” /3.2mm
