Reamers

Chips ahead and behind of reamers are commonly used to obtain very tight ID bore sizes. Drilling an initial hole that is .015″ – .030″ under the desired finished diameter yields the preferable amount of material to be removed with this type of tool. The result is a hole size to .0002″ in diameter and finishes to 16 RMS or better in a single pass, usually eliminating the need for honing.

Solid carbide tip reamers are available in most diameters and lengths to produce close tolerances, eliminating the need for honing.
