A bucket assembly and a method for forming the bucket assembly are disclosed. The bucket assembly includes a platform, an airfoil, and a lower body portion. The platform defines a platform cooling circuit configured to flow cooling medium therethrough. The airfoil extends radially outward from the platform. The lower body portion extends radially inward from the platform. The lower body portion defines a root and a cooling passage extending from the root. The cooling passage is configured to flow cooling medium therethrough. The platform and lower body portion further include a ligament between the cooling passage and the platform cooling circuit. The ligament defines a bore hole extending through the ligament between the cooling passage and the platform cooling circuit. |
