Tag: drill

A drill is a tool fitted with a cutting tool attachment or driving tool attachment, usually a drill bit or driver bit, used for boring holes in various materials or fastening various materials together with the use of fasteners. The attachment is gripped by a chuck at one end of the drill and rotated while pressed against the target material. The tip, and sometimes edges, of the cutting tool does the work of cutting into the target material. This may be slicing off thin shavings (twist drills or auger bits), grinding off small particles (oil drilling), crushing and removing pieces of the workpiece (SDS masonry drill), countersinking, counterboring, or other operations.

Project Profile: Site Sampling Tools

Geophysical surveys can be the bedrock (pardon the pun) of today’s environmental projects, from locating abandoned underground storage tanks (USTs) and utilities, to complex mapping of geology in remedial investigations, to finding landfill boundaries and other buried unknown problems. In the past few decades, a variety of non-destructive testing methods

Perhaps the slopes are too steep. Perhaps the current is too strong. Perhaps both, and maybe some other challenging site conditions exist as well. Some projects along bodies of water require extra-strong measures to stop erosion. One of those projects is in Idaho.

The Vermeer T1255III SEM with single-sided direct drive attachment allows the operator to cut an 80-degree high wall and produces less noise, dust and vibration – helping mines to increase production by excavating reserves they couldn’t otherwise get due to drill and blast restrictions, air quality regulations or urban encroachment.

The Costs and Benefits of Anaerobic Digesters

The Costs and Benefits of Anaerobic Digesters

Anaerobic digesters are a mature, proven technology. They take sludge, manure, and other organic waste materials and produce methane (natural gas) fuel. Nobody questions their technological capabilities. However, the question remains as to their economic benefits. In terms of dollars and cents, how much economic sense do anaerobic digesters make?

Air, Water, and Soil

Air, Water, and Soil

A good piece of vacuum excavation equipment in the fleet can make jobs easier, safer, faster, and more efficient. It can help a company cast a wider net for project opportunities.

A Cosmic Well

A Cosmic Well

Carl Sagan’s book Pale Blue Dot was inspired by a photograph (below) taken as the Voyager 1 spacecraft left for the edge of the solar system on February 14, 1990. The portrait of our world—taken from 4 billion miles away—reveals the vastness of the cosmos relative to Earth’s pixel-sized fleck of blue.

Preventing Erosion with Riprap and Gabion Walls

Preventing Erosion with Riprap and Gabion Walls

Rocks probably were humans’ first construction materials, and they still may be one of our most important.

Loose, as riprap, or contained in gabion walls, they’re ideal for preventing erosion along water channels, ­rivers, creeks, lakes, and oceans.
