Some of the most commonly used tools for do-it-yourselfers are slide hammers, impact hammers and impact wrenches. In fact, the hammer has been used to deliver impact on objects since as early as 2,600,000 BCE. Today, it is used mainly to drive in nails, whereas the impact wrench is the evergreen tool used to drive them out.

Slide Hammer

The slide hammer is essential for those who like to tinker with cars. The user needs to hold the handle of this tool and screw or hook the end into a dent. When the weight installed on the slide hammer is whipped towards the handle, the resultant force exerted pulls out the dent easily.

While the slide hammer is a very useful tool for dent repair, it is imperative that the user exercises caution and control to avoid further damage to the automobile.

Impact Hammer

This tool finds its utility in learning the response of a system or component to impacts of varying amplitude and duration while conducting structural and modal analysis.

A single accelerometer yields transfer and transactional characteristics of the structure. Integrating the responses from several of these devices mounted at various strategic points facilitates modal analysis.

The most critical specifications for impact hammers are force and pulse duration, rated by minimums and maximums. Another common specification is the highest frequency for which the response will be tested, which may be changed by using accessory tips.

These striking tips are available in a range, differing in material composition and hardness. By their very nature, harder tips deform less and have shorter pulse duration than softer ones. Consequently, harder tips are used to measure the highest frequencies.

Impact Wrench

An impact wrench stores energy in a rotating mass. This stored energy may be compared to a hammer. When the trigger is pulled, a motor accelerates this energy and causes it to connect suddenly to the output shaft, an anvil of sorts. The sudden force releases very high torque with minimal effort at the user end. Thus, just like how a user applies relatively little force to a hammer but generates a great impact, so it is with the impact wrench.

Perhaps the most important benefit of these tools is that they are available in a formidable range of sizes and compositions, therefore facilitating users across industries ranging from product assembly to heavy construction.
