E-Z Drill’s Model 210 equipment-mounted concrete drill attachment series consists of three models: the three-gang Model 210-3 EQ MT, four-gang Model 210-4 EQ MT and five-gang Model 210-5 EQ MT. The series is compatible with most models of backhoes and excavators. The pneumatic drills offer specially designed features for maximum productivity and reduced maintenance, making them practical for full-depth road repair and patching projects, according to the manufacturer.
A user-friendly, easily accessible control panel is mounted on the drill to provide convenient operation from the ground. The units are capable of drilling 5/8- to 2 ½-in. (1.6 to 6.3 cm) diameter holes, at a depth of 18 in. (45.7 cm). Each individual drill motor requires a minimum of 100 cfm (2.8 cu m/min) for operation, with a minimum of 300 cfm (8.4 cu m/min) required to power the smallest unit in the series, the three-gang Model 210-3 EQ MT. To reduce air compressor requirements, an optional 120-gal. air tank is available.
Designed for quick, precise drill positioning, the 210 EQ MT drills feature a side-shift control. In contrast to similar equipment-mounted drills, the carrier operator is not required to position the unit in the exact drilling location. The drill must simply be placed in close proximity to the specified drilling area, then can be quickly and easily adjusted to the target location with a toggle switch found on the control panel.
The side-shift feature further enhances productivity by allowing a second set of holes to be drilled without the need to move the drill, backhoe or excavator, provided holes are specified on 12-in. (30.5 cm) centers. Simply set the drill spacing at 24-in. (61 cm), drill one set of holes, and engage the side-shift. The unit will quickly and precisely move 12-in. to drill the second set, all without repositioning the drill or carrier. Drill spacing is adjustable up to 24-in., and the drills offer lateral travel up to 14-in. (35.5 cm).
To reduce operator effort and increase hole-drilling speed, the drills feature a “floating” bucket curl pin. By providing the pin with a small range of motion, the drill automatically levels itself, eliminating the tedious and time-consuming process of manually leveling and positioning the drill with each movement.
For added convenience and productivity, the 210 EQ MT drills feature 360-degree rotation, which allows quick repositioning for drilling within the same patch. To enhance operator safety, the rotating feature includes a safety swivel lock. With the simple flip of a switch, the lock is activated and the drill is secured into place, ensuring safe transport and preventing potential harm to the operator.
A number of features have been incorporated into the 210 EQ MT drills to enhance durability and extend service life. Multi-point oil injection allows each drill to be lubricated individually from a single reservoir, ensuring each drill always has the proper amount of oil. This reduces wear on the motor and is more effective than a central oiling system, which doesn’t offer individual lubrication points. An automatic drill shut-off further extends individual drill life by preventing dry-firing.
The 210 EQ MT drills offer extra height adjustment, providing access to the center of a slab, even in extreme asphalt overlay conditions. To offer a complete system, a full line of drill bits and drill steel is available.
