A rawhide mallet is an excellent example of a dead blow tool used for oil seal installation due to its design and material. Dead blow tools are characterized by their ability to deliver a controlled impact without bouncing back, which helps minimize the risk of damaging the workpiece. The rawhide mallet achieves this by allowing for a softer blow compared to harder metal tools, reducing the potential for marring or denting the surface of the oil seal or surrounding components. This feature is particularly important in delicate applications like oil seal installation, where precision and care are essential for ensuring a proper fit and seal.

In contrast, a rubber mallet, while also soft and effective for various applications, does not possess the same dead blow characteristics. It may still bounce back after impact, potentially making it less suitable for tasks that require controlled application of force. Meanwhile, a ball peen hammer and a claw hammer are both designed for more heavy-duty applications and can cause damage to softer materials, which makes them unsuitable for the specific task of oil seal installation.
