Many tools and manufacturing accessories fall into this category. For instance, handheld drills, sanders, grinders, welders and planers are available as small portable models which can be conveniently transported between work sites. Hammers, spanners, screwdrivers and hand Saws
also fall into this bracket, as do specialist metalworking plates and tables. Supplementary work aids, such as air conditioners, fan heaters and dehumidifiers, are also included, as although they generally do not complete a specific part of the manufacturing process, they are an essential addition to the workplace. Small portable tools are especially relied upon in the construction industry, as their portability and versatility make them an invaluable asset when moving rapidly between sites. Specialist work surfaces, such as welding tables, face angle plates and large-scale surface plates, are not always portable but still provide a versatile and effective solution for niche requirements.
