boring machine, device for producing smooth and accurate holes in a workpiece by enlarging existing holes with a bore, which may bear a single cutting tip of steel, cemented carbide, or diamond or may be a small grinding wheel.
How do you reverse a grundomat?
You can easily reverse the Grundomat during the bore, by adjusting a lever on the lubricator control system. There is no need to turn the air hose or stop the moling tool.
What is a grundomat mole?
Grundomat Mole Soil displacement moles for installing underground services, able to bore up to 50m. The unique reciprocating action stepped-cone chisel head allows displacement of any obstructions. Available from 45mm up to 180mm diameter.
How does a pneumatic mole work?
It works as a pneumatic cylinder with pulsed compressed air causing the head of the mole to repeatedly hammer against the soil in front of the mole. Once the mole has passed through the earth the pipe can be pulled through the long horizontal hole.
How does a GRUNDOMAT work?
The reciprocating stepped-cone chisel head action of the Grundomat piercing tool is unique because it hammers away at solid obstacles. This two-stroke action means that the piston's impact is concentrated on the reciprocating tool head for optimum trenchless boring performance.

How does impact moling work?
Impact moling works best in compressible soils and comes in both steerable and non-steerable types. It works on the simple principle of displacing soil while installing the pipe. Once the borehole is completed, the product pipe is pulled in at the same time that the mole is extracted.24 Jun 2021
How does a pneumatic piercing tool work?
Pneumatic piercing tools are powered by an air compressor. The pneumatic power drives a striker inside the tool forward at a high velocity, and the striker impacts an anvil at the front of the tool, pushing it forward and displacing soil to create the hole for the product to be installed.18 Jul 2017
How does an impact mole work?
The impact mole consists of a steel tube powered by a compressor attached to a piston with a pneumatic hammer placed at the head of the casing. The impact mole is first positioned at the correct line and grade after which the compressor is activated, pushing the mole forward by the hammering action at the head.24 Jun 2021
How does a mole boring machine work?
Operating the Impact Mole The machine works with a hammering action. Each successive blow pushes the mole deeper into the ground, thus making the bore. The impact mole head assembly is conical with a pointed tip. This geometry allows the mole to penetrate the soil and break up small stones in its way.18 Mar 2021
How does a trenchless boring tool work?
Directional boring, sometimes called trenchless digging, is accomplished by piercing the ground with a drilling bit/head at a low angle. The bit is spun and pushed through the soil. Once the desired depth has been met the drilling tip levels out to maintain a horizontal bore.
What is a HammerHead tool?
These pneumatic-powered tools create a compact hole that allows contractors to install underground gas, water, cable, irrigation, fiber or electrical lines under yards, buildings or streets with minimal disruption. HammerHead Mole® piercing tools are some of the most reliable in the industry today.
