For parting off at high feed rates, Horn has introduced the new EH geometry, a development based on the manufacturer's S100 grooving system. The single-edged insert is available in widths of 3mm and 4mm. The stable cutting edge enables feed rates in the range f = 0.25 to 0.4 mm/rev during grooving and parting, leading to fast cycle times. Reliable swarf control and evacuation are ensured by special formation of the chips.
