STILLWATER, Okla. — E-Z Drill introduces the Model 240B “combo” drill system, a versatile machine designed for straight-line drilling on a level subgrade. Similar to the Model 210B, but with the added capability of converting to a core drill, the Model 240B caters to both rock drilling and core drilling applications — eliminating the need for separate drilling systems. The conversion process requires just a few simple tools and can be quickly conducted while on the jobsite.

Featuring totally pneumatic operation, the core drill utilizes a three-speed motor (400, 900 and 1,600 rpm) and requires a minimum of 77 CFM for operation, whereas the standard rock drill configuration requires 100 CFM. The unit can core and drill holes from 5/8-inch diameter up to 2-1/2 inches, and drill up to 18 inches deep.

The compact frame of the 240B allows it to operate in a 4-foot patch while drilling within 6 inches of a corner. Since the unit is operated from the subgrade, it provides an ideal choice when there is insufficient room to operate from the top of a slab, and the machine and user are kept out of traffic lanes. An optional vertical conversion kit enhances the machine’s versatility, allowing it to switch from a horizontal drill to a vertical drill.

When the core drill system is utilized, the unit does not need to be anchored to the concrete, virtually eliminating any set-up time. The operator simply needs to roll the unit to the coring location and begin drilling. The core drill configuration comes standard with a water connection.

The 240B includes numerous features to increase production and help prevent downtime. These include a quick-release bit guide for fast, simple bit replacement and vertical height adjustment for drilling on center with slabs between 6 inches and 24 inches thick. E-Z Drill’s patented roller bearing feed system eliminates friction while drilling, increasing speed and productivity. Drill carriages are easily replaced with basic tools, and quick coupler air fittings further simplify maintenance. Dual-purpose guide wheels on the 240B help with positioning the drill during operation and provide easy jobsite transport.

The drill also features components to protect the machine and the operator. Carriage locks secure the drill and bit in place when the air supply is off or disconnected, and auto-lock couplers automatically secure the air supply hose onto the drill coupling, eliminating the need for manual pinning. Furthermore, the machine includes a lubrication system for extended motor life.

Established in 1987 after creating a solution to slow, handheld rock drills, E-Z Drill now manufactures lines of slab rider drills, on-grade models and equipment-mounted drills, as well as vertical utility models and concrete drilling accessories, such as dust collection systems and cure sprayer trailers. E-Z Drill also can custom design and build automatic drill systems for customers’ specific jobs.
