Choosing The Right Carbide

The larger the volume of the Carbide, the more aggressive the Bit. The more aggressive Carbides assist movement of the chips away from the face as there is more room for airflow on the face of the Bit. These more aggressive Bits help to break out larger chips, which increases the penetration rate. The greater volume of Carbide can lead to longer Bit life.
