The RT1 point geometry features a 140° split point for self-centering entry, reduced thrust, and excellent chip evacuation, with a cylindrical shank sized for standard ER collet chucks and precision drill chucks. DIN 6537L specifies an extra-long flute length relative to diameter, extending reach for deeper-hole applications typical in stainless steel fabrication, medical device manufacturing, and aerospace component drilling. The TiAlN-NANO multilayer PVD coating delivers elevated hot hardness and oxidation resistance above 900 °C, enabling higher cutting speeds and longer tool life compared to standard TiAlN mono-layer coatings.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid #85c94f;padding-bottom:6px;\"\u003eProduct
