An upsurge in the use of small automatic lathes often referred to as Swiss Autos" and generally associated with high volume machining of small precision components in high quality materials has created a demand for a range of reliable easy to turning tools. The heart of any reliable turning tool correctly set and programmed is the insert and how well the cutting edge performs. AC530U is a newly developed tough grade which features our ultra hard Super ZX coat and is particularly suitable for high precision machining of stainless steel and small components using tools like our mini toolholder range promising outstanding reliability at the cutting edge for trouble free machining, high feed rates and long tool life.
