Concrete drill

The Model 65B on-grade concrete drill from E-Z Drill operates on a minimum of 20 cfm. The machine drills holes from 1/2- to 7/8-inch in diameter and can be adjusted to center on slabs as thick as 2 feet. It can drill to 8 inches deep in a 2-foot patch and to a depth of 12 inches in a 30-inch area. The E-Z Drill 65B weighs 65 pounds, allowing it to be loaded, unloaded and repositioned by a single operator. An optional vertical conversion kit increases the unit's versatility, allowing it to switch from horizontal to vertical drilling after a 20-minute installation.
