- Item Features
- 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
- Exceptional performance and tool life using material specific reamer technology and coolant fed capabilities - maximizes feeds and speeds
- Carbide tip brazed to tough hardened alloy steel body
- Polished flutes for easy chip flow
- Precision ground cutting edges
- Flute coolant outlets for reaming through holes as chips are flushed forward through the hole being reamed
- Improves hole finish and permits higher feeds and speeds with longer tool life
- 2-1/4 in L carbide
- The standard 45 deg chamfer angle provides effective cutting action for most materials
- -0.001 in shank diameter tolerance
- 0.0003 in tool diameter tolerance
