TIR of 3/8" holders is about 0.002". However, the smaller the OD (and the longer the cutting tool) the trickier to obtain a small runout. Large diameter cutting tools won't fit through a standard Sherline spindle. Thus, these holders need to be made longer and usually have larger TIR.

TIR of 3/8" holders is about 0.002". However, the smaller the OD the trickier to obtain a small runout. Thus, small diameter pieces may have larger TIR. Similarly the longer the cutting tool the larger the TIR.
