If you need an extension cord, make sure it's of sufficient diameter to transmit the required voltage safely.Īlthough you should try to work with the jackhammer in a nearly vertical position, that's not always possible. Metal casings give more protection than plastic ones.Ī long cord is useful. Jackhammers tend to get pretty rough treatment. If all other things are equal, then a stronger motor is arguably more durable. The power of the electric motor might seem like an important aspect, but most of these tools are over 11 amps, which is plenty.
As a result, powerful impacts can make the jackhammer more difficult to control. While bigger impact forces result in more demolishing power, those impacts are felt through the handles. Ranges vary from 45 to 60 joules, or 33 to 44 ft. Impact force is an area where inexpensive jackhammers sometimes deliver figures as high as the pricier ones. However, because that's an infrequently used unit of measurement, many manufacturers quote foot pounds (ft. With jackhammers, impact force has traditionally been rated in joules. With a swift hammer blow an impact style force is supplied via the leverage bar directly to the socket drive allowing removal or re - tightening.The impact force is the actual amount of energy transmitted with each blow. This tool is a must in any mechanics tool arsenal this unit allows access to tight spaces and difficult areas where impact force is required to remove or replace tight fasteners.
