<![CDATA[In an era where science and technology are rapidly developing, in the era of globalization it opens a wide door for every individual to embrace change. Human resources, being the pulse that pumps industrial life, must be proficient in mastering science and technology, being able to apply it in every step of the industry, and steel has become an important milestone in various sectors, from building construction to machine components. However, behind the glitter of this civilization, technical processes such as turning the HSS M42 chisel face its own challenges. At certain rpm cycles, the tool experiences an erratic level of wear, as evidenced by the difference between the initial and final weights as well as the difference in the initial and final lengths. In the HSS M42 tool turning attempt, the HSS M42 1200 type tool with a size of 3/8x3/8x4" and a rotation speed of 700, 900, and 1200 rpm, with a cutting depth of 1 mm and a feed rate of 0.09, almost encountered a weakness. Tools that wear out quickly, especially at 900 rpm, make turning results less satisfactory. However, there was a light at the end of the hallway. In the same process, the use of HSS tools with HSS M42 1200 type, dimensions of 3/8x3/8x4", was able to answer the challenge with more promising success. At 900 rpm rotation, the wear that occurs is more controlled, resulting in a workpiece with a satisfactory level of fineness, reaching N6 in the measurement of surface roughness. As if to be a symbol of struggle, HSS chisels are able to cut finer traces in the ocean of HSS M42 chisels]]>
