Dormer End mill S521 Nominal Ø 16 mm Radius 3 mm Total length 90 HM TiSiN 45 ° Number of cutting edges 4

The S521 end mill from Dormer is a high-precision tool specifically designed for demanding milling applications in hardened materials. With a nominal diameter of 16 mm and a corner radius of 3 mm, this cutter offers an optimal combination of stability and flexibility. The total length of 90 mm and a cutting length of 17 mm allow for effective machining in various milling techniques, including shoulder milling, plunge milling, and ramp milling. The TiSiN coating provides enhanced wear resistance and extends the tool's lifespan. The cutter is equipped with four flutes that ensure uniform material removal and increase efficiency during milling. The 45° helix angle and -10° cutting angle are ideally suited to the requirements of milling carbide, resulting in high precision and surface quality.

• TiSiN coating for increased wear resistance
• Optimized for milling in hardened materials
• Suitable for various milling techniques such as plunge milling and ramp milling
• Shaft tolerance of h6 for precise fit accuracy
• 45° helix angle for improved chip removal.
