Hand reamers
Hand reamers
The difference between a hand reamer and a machine reamer is that its cutting surface is shorter. When working with hand reamers, a special holder is used. The diameter of hand reamers may range from 3 to 50 mm. Hand reamers are used for cavities processing with the 2nd and 3rd accuracy grade. The holder is put onto the square part of the reamer, then rotational movements are implemented.
