Made to the same dimensions as No.150A drills, these tools are designed specially for drilling Aluminium and
other light alloys where long strings of swarf tend to be formed. They have also been found to be effective in some
free-machining stainless steels. The flute geometry is designed to evacuate stringy swarf and reduce chip-welding.
