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.
