A three gallon (M-12) manually pressurized water pump can is available. It includes an 8 ft. hose and one 10 ft. extension fitted with quick-release connectors.

The drill includes a 1 3/4″ steel service  wrench, but this can be upgraded, at additional cost, to a long-handled 1 3/4″  aluminum wrench for ease of use.  These wrenches are necessary to hold the drive shaft steady for breaking loose and removing drill bits. 

The bits have diamond crowns with 1/8″ wide kerf.   Internal diameters of bits are therefore 1/4″ less than listed O.D.’s.

Bits have an overall length of 17″ and a cutting depth of 14″.
