A tubular radial pin tumbler lock is described. The radial pin tumbler lock has an outer shell, an inner shell housed in the outer shell, and a spindle housed in the inner shell. The spindle has a spindle head with an uneven number of irregular sides. A plurality of radial locking pins are arranged radially from the spindle. A crown on the spindle encases the locking pins. An anti-drill feature is included on the spindle head. An annular space between the inner shell and the spindle head allows access to the radial locking pins for operating the radial pin tumbler lock.
