Solid drill bit A620

for stainless steel

A620 is ideally suited for drilling stainless steels and temperature resistant alloys. A key feature of the A620 is its point geometry. This has been specifically developed to enhance all aspects of hole quality and positional accuracy. It is also particularly advantageous when drilling materials that resist cutting and generate high temperatures, such as stainless steel. In addition, the base material is a Cobalt-based HSS-E (M35), a premium grade of high speed tool steel which has been heat treated to retain hardness at increased temperatures.
