Designed to deliver clean slots and stable tool life in challenging materials, this tool’s extra-short geometry minimizes deflection in tight pockets while the 3-flute configuration supports effective chip evacuation and steady cutting. The combination of powder-metallurgical HSS-E and Alcrona coating reduces wear and friction, helping maintain precise slot widths and smooth finishes across multiple passes. With a Weldon 12 mm shank, it fits standard milling holders for dependable clamping and alignment, making it a practical choice for professional workshops tackling precision milling tasks in ferrous and non-ferrous metals.
