A retainer plate is located at the upper end portion of the carousel to receive and retain the drilling devices in a generally vertical orientation when the drill tower and the carousel are raised to a generally vertical orientation for operative drilling. A primary breaker plate is provided for individually receiving and engaging each drilling device at the lower end portion of the carousel. A secondary breaker plate is located above the primary breaker plate for individually receiving the four drilling devices.
