The Y-Cutter (3-blade, 120°) is the geometry behind Heller's Trijet Ultimate — one line spanning SDS-Plus (Ø5–30) and SDS-Max (Ø12–50), with single-piece carbide at small diameters and multi-piece brazed carbide at large ones. How the Y-Cutter differs from the multi-segment head (Bosch SDS max-7 / ZHMAX-7), why it needs YG11C, and how to specify the right construction for OEM.
