Equipment-Mounted Drills Offer
A Productive Solution For
Full-Depth Concrete Repair Projects

E-Z Drill introduces its Model 210 Equipment-Mounted concrete drill attachment series. Consisting 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 model of backhoes and excavators. The pneumatic drills offer specially-designed features for maximum productivity and reduced maintenance, making them ideal for full-depth road repair and patching projects.

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 16 to 63.5 mm (5/8- to 21/2’’) diameter holes, at a depth of 457 mm. Each individual drill motor requires a minimum of 2.8 m3/min (100 CFM) for operation, with a minimum of 8.4 m3/min (300 CFM) required to power the smallest unit in the series, the three-gang Model 210-3 EQ MT. To reduce air compressor requirements, an optional 450 l 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.

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 does not 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.
