A shrink-fit holder gives the slimmest profile and the highest runout accuracy, and it needs a shrink machine. A hydraulic holder clamps with a hex key, damps vibration and is the practical choice for reaming and finishing. A mechanical high-precision holder is the cheapest per station and the most tolerant of shop conditions. Send the operation and the machine and Mongtec will say which one is worth the money.
