To obtain the best results when using reamers it is essential to make them work. It is a common fault to prepare holes for reaming with too little stock left in. If insufficient stock is left in the hole before reaming then the reamer will rub quickly; show wear and will result in loss of diameter. It is equally important for performance not to leave too much stock in the hole.
