Many Proxxon tools such as 28440, 28481, 28485, 28500, 28510, 28620 are designed for collets, held and clamped by a collet nut. These tools do not have a sufficiently long threaded spindle to accept the Proxxon MICROMOT chuck 28941 and allow it to close fully.
For this reason we also offer the Relativity 3.2mm chuck, which has a smaller body diameter which fits inside the nose shroud of 28440, 28481, 28485, 28620, 28500, 28510.
Specify which Proxxon tool you have, so we can supply the correct Long version or Short version of the 3.2mm chuck.
