E-Z Drill, Still Water, Okla., has introduced the model 240B SRA combo drill system. Combining the standard features of the model 210B SRA with the capability of converting to a pneumatic core drill the model 240B SRA caters to both rock drilling and core drilling application. The core drill uses a three-speed motor (400, 900 and 1,600 rpm) and requires a minimum of 77 cfm for operation. The unit can core and drill holes from 5/8-inch diameter up to 2 ½ inches, and drill up to 18 inches deep. The 240B SRA’s compact frame design allows the unit to operate in a 4-foot patch while drilling to within 6 inches of a corner. The core drill does not need to be anchored to the concrete. The core drill configuration comes standard with a water connection. For added versatility, the 240B SRA can drill vertically with either the rock drill or core drill configuration after a few adjustments.
