Precision Brush - Face of Inside Coil Brush

Sizing the Face or "Length" of inside coil brushes can be tricky. Sometime the critical dimension would be the maximum number of loops in a compressed state, sometime it is considered the natural relaxed state of the brush and sometime the brush is stretched out to a certain number of loops, similar to an "Open Wound Coil brush". The number of loops within a given face length can also depend on how much bunching of filaments occur at the ID. It may be impossible to make the channel of each loop touch each other.
