Abstract
A cluster drill includes a first plate portion and a second plate portion. The first plate portion extends parallel to the second plate portion and is rigidly affixed to the second plate portion. At least one first and second plate aperture is formed in the first and second plate, respectively. At least one modular retainer unit, to be mounted within the first and second plate apertures, retains a first and second portion of a rock drill apparatus. A cannister affixes the first plate portion relative to the second plate portion. The cannister may be either cylindrical or contain protuberances to accommodate the modular retainer unit. A drill bit lock restricts motion between the a drill bit and the second plate when desired.
