*Shanks are designed to fit plain collets as thread crests are below shank diameter, as well as Clarkson and
similar threaded collets. A metric standard, DIN1835 Type D, has been used to describe the shanks.

NOTE RELATING TO 623 series mills— 3-Flute cutters stand between 2-flute slot drills and multiflute end mills. Continental
suppliers generally default to the shorter DIN327 (Slot Drill) lengths, whereas British makers have usually followed the longer End Mill
data for threaded shank 3-Flute. This leads to some terminological confusion. Large stocks exist of cutters made to DIN327 long series,
but with combination (Flatted+Threaded) shanks. They are of very similar length to DIN623L above, and may be offered in place of
623L where the definitive item is not available. The combi shank tools are available only while stocks last, and then become special.
