The Fiberglass Pole Bits / Composite Pole Bits / are for hollow core composite or fiberglass poles and are generally preferred when creating holes in hollow core poles, cross arms, supports, and braces.  The amount of debris created when drilling hollow core product is minimal thus a less fluting is required.  The Fiberglass Pole Bits for hollow core poles are not recommended for solid core poles and structures - debris created when drilling solid core poles and structures is greater and require greater fluting.  B & A Fiberglass Pole Bits are designed to eliminate bit whipping in the air gap of the hollow core structure and preventing distortion of the initial hole and allows proper in field exit hole alignment. 

For Solid Core Composite Structures, poles, braces, cross arms, and supports - B & A recommends the FGS Series.
