A reamer is used to finish machine a previously formed hole to an exact diameter with a smooth finish. It should not be used to significantly enlarge a hole (max. 5% – depending on material and hardness). Carbide tipped reamers are especially appropriate for close tolerance reaming. Because carbide is very highly resistant to wear, the reamer will produce accurate hole size and a smooth finish far longer than high speed steel or cobalt. The reamer is an end cutting tool, cutting only on the chamfer’s edge at the outside diameter of the preformed hole. The standard 45° chamfer angle provides effective cutting action for most materials.
