This is our most popular drill guard and suits most smaller pedestal and bench belt drive drilling machines. 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 40mm to 70mm diameter. This guard can accommodate drill chucks with an outside diameter of up to 55mm. 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.

The guard concertinas upon contact with the work piece and the lower sections depth can be set by adjustable stops. The guard pivots up with over centre springs to hold the guard open for access to the chuck.
