Mighty Mole Horizontal Boring Equipment

Mighty Mole Horizontal Boring for skid steers, mini skid steers, and mini excavators

McLaughlin’s (a Vermeer Co.) “Mighty Mole” Hydraulic Horizontal Boring Attachments are powered by hydraulics, capable of producing bores up to 4-1/2″ diameter using the dry compaction boring method of drilling. Speeds of 8′ per minute and distances of 100′ are possible depending on soil conditions. Wet boring allows diameters up to 10″.

McLaughlin’s Mighty Mole Horizontal Boring Attachment is available in four distinct models: skid steer, mini skid steer, mini-excavator, and weld-on (not listed, please call). When ordering, you additionally order a Moleing Package which provides the most-common setup of 60′ of drill rod and a basic moleing head (1/34″). Add additional heads for progressively reaming larger diameters.

Various Models Available – Even a Pit Boring Version

The original M-4500 Weld-On Unit is attached to the skid steer bucket with a weld-on bracket and boring attachment can quickly be installed and removed with a pin connection.

The M4500SS Skid Steer Model is a Hydraulic Boring Attachment for full-size skid steer and includes a Quick attach plate. Includes manual and T-Handle guide, Drill Rods to 60′ and a Moling head to bore a 1 3/4″ hole, a reamer to increase your bore to 2.5″… or to 3.5″ or 4.5″ with additional reamers. The M4500SS comes with a quick attach backplate and has (3) different pin-in-place boring positions for the moleing attachment to allow for center, left, and right attachment positions for working close to buildings or existing structures.

The M4500MS Mini Skid Steer Boring Attachment includes a quick-attach backplate and a center-mounted moleing attachment with a quick-detach pin kit.

The M4500ME Mini Excavator Boring Attachment works with any mini-excavator bucket and is a wedge design that attaches to the bucket blade and is strapped in place.

– Bore Diameter: 1-1/4″ to 4-1/2″ (3.2 cm – 11.4 cm)
– Motor: Hydraulic with forward/reverse

Here’s how it works: You bore 1 3/4″. From the far pit, you attach the 2.5″ reamer with the “Chinese finger” and pull the reamer and the pipe back to you. If you want a 3.5″ bore you send the rod again to the far pit, attach the 3.5″ reamer and pull back. Do the same with the 4.5″ reamer, which requires a 3.5″ bore first.
