Munce Discovery Burs feature round carbide heads on 31mm (Shallow Trougher) and 34 mm (Deep Trougher) non-flexible shafts that facilitate positive troughing control for locating separated instruments and uncovering hidden canals.

Along with the newly released diamond-tipped TruGrit Trough Refiner, these longer-than-standard-length burs draw the handpiece head away from tooth structure, creating the favorable geometry that opens a functional view corridor to the deep target area.

In contrast to standard 2.35 mm shaft diameters, the narrow shafts of Munce Discovery Burs — 0.7 mm on the three smallest head sizes and 1 mm on all other head sizes — prevent shaft impingement on deep access cavity walls, significantly reducing ledging and perforation risk while preserving the shaft stiffness required for troughing-type procedures.

In addition, the 0.7 mm shaft diameter on the smallest head sizes allows parallel cement-line dissection around posts and post core-out procedures and offers visibility of the tiny heads in such operations as exploring for calcified canals deep within root structure where visibility would otherwise be blocked by standard-diameter shafts.

Also now available is a new bur block designed to hold the full complement of Munce Discovery Burs, including the TruGrit Trough Refiner.
