With the new 240B SRA “combo” drill system, E-Z Drill is touting “a new concept in concrete drills.” The 240B SRA combines the standard features of the established 210B SRA model with the ability to convert to a pneumatic core drill, thus catering to both rock drilling and core drilling applications, and eliminating the need for separate systems. The core drill utilizes a three-speed motor and requires a minimum of 77 cubic feet per minute of air for operation.
