A hammer drill may be sufficient for drilling small-diameter holes in soft masonry, some metals and other materials too hard for conventional drills, but when tackling harder materials, such as concrete or cement blocks and brick, a rotary hammer is the most efficient.
The hole saw is a ubiquitously necessary tool. You would be hard-pressed to find an electrician who does not have at least one in his or her toolbox, or an electrical contractor without a hole saw kit or two back at the shop.
This year marks the 100th anniversary of the portable electric drill’s invention. A century ago, the Black + Decker Manufacturing Co. (now Stanley Black + Decker) developed and filed a patent application for a ½-inch portable drill that one person could operate.
Power hand tools have advanced rapidly over the last few years, becoming more powerful, productive, lighter and easier to use. Along with other useful convenience features, most of today’s cordless drills have light-emitting diodes (LEDs) to illuminate the work area.
Construction in most trades uses saws to cut off and cut through various materials, and electrical work is no exception. Cordless saws continue to capture a growing share of the market, though there still are applications where corded saws are preferred.
Installers of alarm, surveillance and control systems use special tools designed for low-voltage copper and fiber work, but they also often need conventional tools used by electricians and other trades.
A rotary hammer is the tool of choice for most electricians who must make holes in concrete, block and brick. Small rotary hammers are used primarily for drilling holes to install anchors for hanging Unistruts for electrical conduit.
The electric demolition hammer is not a standard item found in most electricians’ tool boxes. Indeed, even the most compact and lightweight demo hammer is too big and heavy to carry with the tools routinely used on most jobs.
Your employees work with an abundance of hand and power tools. You can help keep them safe by ensuring they are well-versed in common-sense tool safety. Although we all should know the following 10 safety tips, a review never hurts.
Construction workers face numerous and varied job-site dangers, depending on the type of work they do. In addition to risks common to most construction jobs, electricians face the hazard of electric shock and other dangers associated with live power.
The evolution of Basic tool types occurs slowly (think screwdrivers and measuring tapes). Then there are times when a new tool technology (or the advancement of an old approach) rapidly changes a market segment (e.g., lithium-ion batteries for professional hand tools).
Most successful companies today—including those that manufacture the tools used by electricians—say they are market-driven. That means while sales are essential, the products or services a company offers must be driven by need.
Horizontal directional drilling (HDD) is an innovative “trenchless” construction procedure. It has been in use for a dozen years to make trenchless installations of cable, conduit and duct in areas where surface improvements or crowded utility easements make excavation impractical or impossible.
