Achieve greater efficiency with the 110B single-gang, on-grade drill that’s equipped with dual-purpose guide wheels to quickly transition from riding along the face of the slab to moving around the jobsite. The drill operates on the subgrade and fits in a 3-foot patch. A minimum of 50 cfm is required to run the totally pneumatic system, which can drill holes as deep as 12 inches in diameters of 5/8 of an inch to 2 inches. Users can install the optional hole spacing guide, which clearly indicates where to place the 170-pound drill, for even greater accuracy and efficiency when repositioning.
