Little Beaver’s two horizontal boring attachments turn versatile Little Beaver Mechanical Earth Drills into precise, timesaving horizontal machines for a variety of applications including conduit, pipe, and irrigation installments.
Little Beaver’s Horizontal Boring Kits are easier than physically forcing a pipe through soil by hand, and more cost effective than purchasing or renting expensive hydraulic and pneumatic moles, especially for those who already have a Little Beaver Mechanical Earth Drill.
Coupled with a Little Beaver Mechanical Earth Drill, the Dry Auger Kit can efficiently create small bores up to 5 feet long. The kit includes a 5-foot auger with a 3-inch diameter bit, a horizontal drill key, and 5-foot extension with a universal wiggle joint. With the extension connected to the auger by the wiggle joint, users are able to stand while boring. The earth drill provides the torque necessary to drill smoothly through the soil from one side of the sidewalk to the other.
Due to the low drilling load, torque tubes are unnecessary with horizontal boring. Instead, users attach a horizontal drill key to the torque tube connector on the power unit to engage the safety interlock and bypass the engine kill switch.
The Wet Drilling Kit is ideal for jobs that require horizontal boring to lengths up to 50 feet, such as those under driveways and streets. The kit includes a choice of a 2-, 3- or 4-inch water drill bit, plus a swivel adapter, the swivel assembly and horizontal drill key. Users will need a garden hose or pump and enough 3/4-inch Schedule 80 water pipe and 3/4 -inch pipe couplings to complete the job. The water swivel assembly connects between the swivel adapter on the drill handle and the 3/4-inch water pipe. The garden hose attaches to the swivel adapter and the water drill bit is screwed on the leading end of the water pipe.
Boring may begin once the user has assembled the kit’s pieces and dug a starter trench. Users should have as much water pipe as necessary for the job plus an additional 15 feet to create a bow between the water pipe in the starter trench and the drill. For example, a 45-foot long bore will be made with 60 feet of water pipe. The bow provides users with a direct angle to smoothly drive the drill through the soil while standing, similar to the wiggle joint extension in the sidewalk auger kit. Water runs from the garden hose or pump to the Wet Drilling Kit, starting with the water swivel and the water pipe, and then out the end of the drill bit. The action of the flowing water flushes the cuttings from the hole to make a complete bore parallel to the pavement above.
