The Trocar HB and HBX both feature 0.035-inch-thick surgically sharp stainless steel mechanical blades that stay tucked in tight to the solid-steel ferrule in flight, but they deploy reliably with a 1 5/8” expandable cutting diameter. The fixed blades are also 0.035-inch thick and have a cutting diameter of 1”. They have an offset for increased accuracy and stability. The total cutting diameter of the HB and HBX is 2 5/8”. The Trocar HB and HBX feature a bone-crushing chisel tip.
