These three models are the next size up from the above listed BT/2 drill guards. These guards are constructed from special aluminum extrusions with front clear polycarbonate windows for viewing.
The guard clamps to the bottom of the quill (Section that moves up and down but doesn’t rotate). Most drilling machines of this belt drive type have a round boss or section at the bottom of the quill suitable for fixing the drill guard to. A length of about 12mm is required. Clamping sizes range from 41mm to 100mm diameter. This guard can accommodate drill chucks with an outside diameter of up to 70mm. Note that sometimes the depth stop lower casting (generally pear shaped) is located right at the bottom of the quill but this casing can generally be unpinned or unclamped and relocated 12mm higher up the quill providing a guard clamping position below the casting.
