Hand reamers have a square on the end of the shank which allows placement into a wrench which the user rotates by h&. Used for opening out & finishing existing holes to H7 tolerance in most ferrous & non-ferrous metals. Flute Geometry
- 7° Helix Left hand spiral. 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 & will result in loss of diameter. It is equally important for performance not to leave too much stock in the hole.
