Description

The Dormer M Machine Tap is engineered for high-performance metric threading in a variety of industrial applications. Built with a premium HSS-E-PM powder metal substrate, this tap provides superior abrasion resistance and edge strength for demanding tasks. The straight flute design and bright finish are optimized to prevent built-up edge when working with sticky materials, making it ideal for both blind and through holes up to 1.5xD. Designed primarily for use on CNC machines, this tool delivers consistent results across diverse materials including steel under 1200 N/mm2, cast iron, copper, brass, aluminum alloys, composites, and thermosetting plastics.
