The combination of powder-metallurgical HSS-E and a 45° helix provides efficient chip evacuation and sharp, stable cuts across tough materials. The bright finish helps resist built-up edge, while the Weldon 6 mm shank ensures secure seating and reduced runout for precise, repeatable milling. Ideal for high-precision shoulder, slot, and ramping operations, this end mill supports cleaner finishes, longer tool life, and fewer tool changes in demanding production environments.
