New chipbreaker geometry end mills

The new VQ-CS range of chipbreaker end mills includes medium and long cut length types named VQJCS and VQLCS. They have been designed for specialised roughing applications on heat resistant super alloys. The main features of these new end mills are the special flutes that have notches to provide an effective chip breaking function. The 5 flutes used on each diameter features a rigid cross-sectional geometry to provide excellent chip evacuation, this makes the VQCS end mills ideal for trochoidal machining.
