The reamer is used to finish machine a previously formed hole to an exact diameter with a smooth finish
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
Geometry and carbide grade appropriate for material being machined
Higher feeds and speeds due to heat resistant cutting edge - reduces machine cycle time per part
Consistent quality - maintains hole size and surface finish far longer
Longer tool life - reduces down time for tool changes
Superior performance over high speed steel and cobalt - good in a wide variety of materials
Polished flutes for easy chip flow
Precision ground cutting edges
The standard 45 deg chamfer angle provides effective cutting action for most materials
