Ød Part Ød Part Collet shank sizes
shank number shank number The ER collet series was designed to be
3mm NER4000030 1/2” NER4000127 compressible. Often marked with two sizes,
4mm NER4000040 13mm NER4000130 the larger dimension is the machined bore
5mm NER4000050 14mm NER4000140 size.
6mm NER4000060 16mm NER4000160 Cutter life and cutting performance are
1/4” NER4000063 18mm NER4000180 reduced when the collet size does not
8mm NER4000080 20mm NER4000200 exactly match the cutter shank. Therefore
3/8” NER4000095 22mm NER4000220 if a collet is marked, for example 6-5, it
10mm NER4000100 24mm NER4000240 should only be used for cutters of 6mm
12mm NER4000120 25mm NER4000250 shank and not any smaller.
