I have bought a few Carbide tool holders, my lathe has a center height of 12mm (i do not have an adjustable quick change tool post).
The straight, LH & RH holders are the correct height but the boring bar requires a 6.4mm packer to achieve center.
Is there a logical reason for this as I find it strange.
