A hand grinder is a grinder generally powered by compressed air (although there are also electric ones), designed for abrasion, cutting or polishing tasks in small spaces or precision work, which can work with various accessories. It is a compact variant of traditional drills, with lower weight and dimensions, but with greater handling versatility.[1][2].
Description
The grinding wheel rotates at a relatively high speed to achieve sufficient tangential speed even with small-sized grinding wheels. The speed is controlled by the applied air pressure. Compared to electrical devices, compressed air devices are characterized by their lower power-to-weight ratio.
Electric models consist of a small motor (between 5000 and 30000 RPM), an ergonomic housing and a spindle with a type of chuck where the discs or interchangeable grinding wheels are assembled. Its power usually ranges between 50W and 500W, depending on its use: from DIY to industrial or dental applications.
Characteristics
Pneumatic grinders work with compressed air and stand out for:.
They are primarily used in industrial environments to deburr edges of metal parts, but accept multiple accessories (grinding wheels, burs, polishing discs, etc.). They can also be equipped with various accessories, such as discs or other cutting accessories.
Security
Like all grinders, they require protective glasses and a tight-fitting hose to prevent flying fragments. In some models, they incorporate anti-vibration protectors or electronic brakes for greater control.
Impact on health
Although hand-held power tools are useful, they also produce large amounts of noise, vibration[3] and particles, including ultrafine particles.[4] Airborne particles are a group 1 carcinogen.[5] atmospheric,[6] as they can penetrate deep into the lungs and brain from the bloodstream, causing health problems such as heart disease, lung disease and premature death.[7] There is no safe level of particles. A 2013 study concluded that "air pollution from suspended particles contributes to the incidence of lung cancer in Europe."[8] Worldwide, exposure to PM 2.5 contributed to 4.1 million deaths from heart disease, stroke, lung cancer, chronic lung diseases and respiratory infections in 2016.[9] Typically, suspended particles in the environment are.[10].

Impact on health
There are some industry standards for the size and amount of dust emitted by power tools,[11][12] although they do not appear to be widely known or used globally. Knowing that dust is generated throughout the construction process and can cause serious health risks,[13] manufacturers now market power tools equipped with dust collectors (e.g., HEPA vacuum cleaners) or integrated water delivery systems that remove dust after emission.[14][15] However, the use of these products is still not common in most locations. Starting in the first quarter of 2024, gasoline tools are prohibited in California.[16].
The use of power tools without hearing protection for an extended period of time can put a person at risk of hearing loss. The United States National Institute for Occupational Safety and Health (NIOSH) has recommended that people not be exposed to noise equal to or greater than 85 dB, for purposes of preventing hearing loss. some even exceed 100 dB.[18] NIOSH strongly recommends wearing hearing protection while using these types of power tools.[19].
