Product Description

Reamers are precise cutting tools used to enlarge existing holes smoothly and accurately by removing a small amount of metal. Reamer geometry varies widely, which is four or more flutes, spiral or straight, left or right hand cut.

Applications: Reamers are used to rough or finish ream predrilled, punched, or die-cast cavities for improved size, roundness, straightness, and surface finish. Though straight flute reamers are still popular, there are many advantages to spiral flute construction. Particularly in smaller sizes, spiral flute reamers can be manufactured more accurately and result in a considerable cost savings.
