The S523 end mill from Dormer is a high-precision tool specifically designed for demanding milling applications in hardened materials. With a nominal diameter of 12 mm and a corner radius of 2 mm, this cutter offers an optimal combination of stability and flexibility. The TiSiN coating enhances wear resistance and extends the tool's lifespan. The cutter features four cutting edges that enable efficient chip removal and reduce machining time. With an overall length of 75 mm and a cutting length of 25 mm, the S523 is ideal for various milling processes, including shoulder milling, plunge milling, and ramp milling. The special geometry with a 40° helix angle and a -6° rake angle ensures excellent chip evacuation and high surface quality.
